#AtacamaLargeMillimeterSubmillimeterArray

Dr. Juande Santander-VelaA group led by Fujimoto-san et al have uncovered a primordial galaxy, just 930 million years after the Big Bang (z=6.072). The galaxy is composed of at least 15 dense, star-forming clumps embedded within a rotating disk like a "Cosmic Grape". These clumps, with sizes ranging from 10 to 60 parsecs, dominate 70% of the galaxy's UV light, and are reshaping our understanding of early galactic structure formation. More than 100 hours of joint ALMA and JWST observations were made, amplified by gravitational lensing, making this one of the most studies early galaxies.More information on <a href="https://www.almaobservatory.org/en/press-releases/alma-and-james-webb-space-telescope-shed-light-on-cosmic-grapes/" rel="nofollow noopener" translate="no" target="_blank">https://www.almaobservatory.org/en/press-releases/alma-and-james-webb-space-telescope-shed-light-on-cosmic-grapes/</a><a href="https://mathstodon.xyz/tags/ALMA" class="mention hashtag" rel="nofollow noopener" target="_blank">#ALMA</a> <a href="https://mathstodon.xyz/tags/AtacamaLargeMillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterArray</a> <a href="https://mathstodon.xyz/tags/AtacamaLargeMillimeterSubmillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterSubmillimeterArray</a> <a href="https://mathstodon.xyz/tags/JWST" class="mention hashtag" rel="nofollow noopener" target="_blank">#JWST</a> <a href="https://mathstodon.xyz/tags/GalaxyEvolution" class="mention hashtag" rel="nofollow noopener" target="_blank">#GalaxyEvolution</a> <a href="https://mathstodon.xyz/tags/OriginOfGalaxies" class="mention hashtag" rel="nofollow noopener" target="_blank">#OriginOfGalaxies</a> <a href="https://mathstodon.xyz/tags/EarlyUniverse" class="mention hashtag" rel="nofollow noopener" target="_blank">#EarlyUniverse</a> <a href="https://mathstodon.xyz/tags/PrimordialGalaxies" class="mention hashtag" rel="nofollow noopener" target="_blank">#PrimordialGalaxies</a> <a href="https://mathstodon.xyz/tags/GrapeLikeGalaxies" class="mention hashtag" rel="nofollow noopener" target="_blank">#GrapeLikeGalaxies</a>

mauricioaraya.com · Blog do Maurício ArayaPela primeira vez, astrônomos testemunham nascer de um novo sistema solarPesquisadores internacionais identificaram, pela primeira vez, o momento em que os planetas começaram a se formar em torno de uma estrela além do Sol. Usando o telescópio Atacama Large Millimeter/submillimeter Array (Alma), do qual o Observatório Europeu do Sul (ESO) é parceiro, e o telescópio espacial James Webb, eles observaram a criação das primeiras partículas de material formador de planetas — minerais quentes começando a se solidificar. Esta descoberta marca a primeira vez que um sistema planetário foi identificado em um estágio tão inicial de sua formação e abre uma janela para o passado do nosso próprio Sistema Solar.“Pela primeira vez, identificamos o primeiro momento em que a formação de planetas é iniciada em torno de uma estrela diferente do nosso Sol”, diz Melissa McClure, professora da Universidade de Leiden, na Holanda, e principal autora do novo estudo, publicado na revista Nature.A coautora Merel van ‘t Hoff, professora da Universidade Purdue, Estados Unidos, compara suas descobertas a ‘uma imagem do Sistema Solar bebê’, dizendo que “estamos vendo um sistema que se parece com o que nosso Sistema Solar parecia quando estava apenas começando a se formar”.Este sistema planetário recém-nascido está emergindo em torno de HOPS-315, uma ‘proto’ ou estrela-bebê que fica a cerca de 1,3 mil anos-luz de distância de nós e é um análogo do Sol nascente. Ao redor dessas estrelas bebês, os astrônomos frequentemente observam discos de gás e poeira conhecidos como ‘discos protoplanetários’, que são os locais de nascimento de novos planetas. Embora os astrônomos já tenham observado discos jovens que contêm planetas recém-nascidos, massivos e semelhantes a Júpiter, McClure afirma: “sempre soubemos que as primeiras partes sólidas dos planetas, ou ‘planetesimais’, devem se formar em estágios mais remotos, em estágios iniciais”.Em nosso Sistema Solar, o primeiro material sólido a se condensar próximo à localização atual da Terra ao redor do Sol é encontrado preso dentro de meteoritos antigos. Astrônomos datam essas rochas primordiais para determinar quando o relógio começou a contar a história da formação do nosso Sistema Solar. Esses meteoritos são repletos de minerais cristalinos que contêm monóxido de silício (SiO) e podem se condensar nas temperaturas extremamente altas presentes em discos planetários jovens. Com o tempo, esses sólidos recém-condensados se unem, semeando as sementes para a formação de planetas à medida que ganham tamanho e massa. Os primeiros planetesimais com quilômetros de extensão no Sistema Solar, que cresceram e se tornaram planetas como a Terra ou o núcleo de Júpiter, formaram-se logo após a condensação desses minerais cristalinos.Com a nova descoberta, os astrônomos encontraram evidências de que esses minerais quentes começam a se condensar no disco ao redor de HOPS-315. Seus resultados mostram que o SiO está presente ao redor da estrela bebê em seu estado gasoso, bem como dentro desses minerais cristalinos, sugerindo que ele está apenas começando a se solidificar. “Esse processo nunca foi observado antes em um disco protoplanetário — ou em qualquer lugar fora do nosso Sistema Solar”, afirma o coautor Edwin Bergin, professor da Universidade de Michigan, Estados Unidos.<a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://mauricioaraya.com/tag/alma/" target="_blank">#Alma</a> <a rel="nofollow noopener" class="hashtag u-tag u-category"

Dr. Juande Santander-VelaThis is my second migration on Mastodon, so I think an Introduction might be in order. I'm moving in to this account (that had lived independently, to test some of Mathstodon features) after astrodon.social is being sunset. Hope that Astrodon as a concept still lives!I currently work in Systems Engineering for radio telescopes (in particular, the ALMA radio interferometer). I’ve also worked in software development and management for the SKAO observatory, and for the archive department at ESO. Of course, I'm also very interested in math (specially that having to do with system theory), so I'll try to get a bit stronger there.Glad to see you all around!<a href="https://mathstodon.xyz/tags/Introduction" class="mention hashtag" rel="nofollow noopener" target="_blank">#Introduction</a> <a href="https://mathstodon.xyz/tags/SystemsEngineering" class="mention hashtag" rel="nofollow noopener" target="_blank">#SystemsEngineering</a> <a href="https://mathstodon.xyz/tags/SystemTheory" class="mention hashtag" rel="nofollow noopener" target="_blank">#SystemTheory</a> <a href="https://mathstodon.xyz/tags/RadioTelescopes" class="mention hashtag" rel="nofollow noopener" target="_blank">#RadioTelescopes</a> <a href="https://mathstodon.xyz/tags/ALMA" class="mention hashtag" rel="nofollow noopener" target="_blank">#ALMA</a> <a href="https://mathstodon.xyz/tags/AtacamaLargeMillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterArray</a> <a href="https://mathstodon.xyz/tags/AtacamaLargeMillimeterSubmillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterSubmillimeterArray</a> <a href="https://mathstodon.xyz/tags/SKAO" class="mention hashtag" rel="nofollow noopener" target="_blank">#SKAO</a> <a href="https://mathstodon.xyz/tags/SquareKilometreArrayObservatory" class="mention hashtag" rel="nofollow noopener" target="_blank">#SquareKilometreArrayObservatory</a> <a href="https://mathstodon.xyz/tags/ESO" class="mention hashtag" rel="nofollow noopener" target="_blank">#ESO</a> <a href="https://mathstodon.xyz/tags/EuropeanSouthernObservatory" class="mention hashtag" rel="nofollow noopener" target="_blank">#EuropeanSouthernObservatory</a> <a href="https://mathstodon.xyz/tags/Astrodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#Astrodon</a>

Dr. Juande Santander-VelaUsing data from ALMA and advanced simulations, a research team led by Santiago Orcajo from the Instituto de Astrofísica de La Plata in Argentina (CONICET and Universidad Nacional de La Plata) has presented a new model that traces the evolution of protoplanetary disks through five distinct stages. The results strongly support a planet-driven origin of these substructures and offer new insights into how planets interact with the disks in which they form.Stage I: Very young disks with shallow or no obvious substructures, corresponding to an epoch in which protoplanets are not massive enough to carve noticeable gaps in the disks.Stage II: Disks with relatively narrow, but clear gaps and rings, indicating the growth of protoplanetsStage III: A rapid widening of the gaps due to the sudden growth in the mass of some planets when they acquire their gaseous envelopes. This stage includes the rapid accumulation of dust at the outer edges of the gaps (the inner rims of the outer disks) due to the strong “pressure bumps” caused by the giant planets that recently formed, which stops the inward drift of dust.Stage IV: Dust filtration at the edges of the cavities, resulting in dust-depleted inner disks. The millimeter dust from the outer disks efficiently drifts in and accumulates at the edges of the gaps.Stage V: Eventually, the dusty inner disks drain completely onto the stars, and the outer disks become narrow rings (or collections of narrow rings).More info: <a href="https://www.almaobservatory.org/en/press-releases/alma-inspires-new-models-for-the-evolution-of-planet-forming-disks/" rel="nofollow noopener" translate="no" target="_blank">https://www.almaobservatory.org/en/press-releases/alma-inspires-new-models-for-the-evolution-of-planet-forming-disks/</a><a href="https://astrodon.social/tags/ALMA" class="mention hashtag" rel="nofollow noopener" target="_blank">#ALMA</a> <a href="https://astrodon.social/tags/AtacamaLargeMillimeterSubmillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterSubmillimeterArray</a> <a href="https://astrodon.social/tags/AtacamaLargeMillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterArray</a> <a href="https://astrodon.social/tags/ProtoplanetaryDisks" class="mention hashtag" rel="nofollow noopener" target="_blank">#ProtoplanetaryDisks</a> <a href="https://astrodon.social/tags/PlanetFormation" class="mention hashtag" rel="nofollow noopener" target="_blank">#PlanetFormation</a> <a href="https://astrodon.social/tags/YoungStars" class="mention hashtag" rel="nofollow noopener" target="_blank">#YoungStars</a> <a href="https://astrodon.social/tags/YoungSolarSystems" class="mention hashtag" rel="nofollow noopener" target="_blank">#YoungSolarSystems</a>

Dr. Juande Santander-VelaAn international collaboration called exoALMA is using our telescopes to s peer through the dusty disks where planets are born. Thanks to their newly developed advanced imaging techniques, exoALMA has revealed the most sharp images of young solar systems, as never seen before. This research project has just published 17 papers, with several more coming on the several months. The exoALMA collaboration is using ALMA to conduct a comprehensive planet hunting campaign in the sub-mm regime. They claim to be the first to focus on still-forming planets, instead of fully formed ones.Unlike traditional planet-hunting methods that look for a young planet's direct light, exoALMA looks for the effects planets have on their surroundings. This approach potentially allows to detect much younger planets than ever before. "It's like trying to spot a fish by looking for ripples in a pond, rather than [the] fish itself.”More information on the link below:<a href="https://www.almaobservatory.org/en/press-releases/exoalma-survey-reveals-incredible-images-of-structures-in-protoplanetary-disks/" rel="nofollow noopener" translate="no" target="_blank">https://www.almaobservatory.org/en/press-releases/exoalma-survey-reveals-incredible-images-of-structures-in-protoplanetary-disks/</a><a href="https://astrodon.social/tags/ALMA" class="mention hashtag" rel="nofollow noopener" target="_blank">#ALMA</a> <a href="https://astrodon.social/tags/AtacamaLargeMillimeterSubmillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterSubmillimeterArray</a> <a href="https://astrodon.social/tags/AtacamaLargeMillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterArray</a> <a href="https://astrodon.social/tags/exoALMA" class="mention hashtag" rel="nofollow noopener" target="_blank">#exoALMA</a> <a href="https://astrodon.social/tags/ExoPlanets" class="mention hashtag" rel="nofollow noopener" target="_blank">#ExoPlanets</a> <a href="https://astrodon.social/tags/YoungStars" class="mention hashtag" rel="nofollow noopener" target="_blank">#YoungStars</a> <a href="https://astrodon.social/tags/StarFormation" class="mention hashtag" rel="nofollow noopener" target="_blank">#StarFormation</a> <a href="https://astrodon.social/tags/PlanetFormation" class="mention hashtag" rel="nofollow noopener" target="_blank">#PlanetFormation</a> <a href="https://astrodon.social/tags/YoungPlanets" class="mention hashtag" rel="nofollow noopener" target="_blank">#YoungPlanets</a>

Dr. Juande Santander-VelaALMA Discovers “Space Tornadoes” Around the Milky Way’s Core!Although the galaxy’s central molecular zone (CMZ) has long been known to be filled with swirling dust and gas molecules cycling through formation and destruction, the mechanism that drives this process has remained elusive. Molecules serve as tracers for various processes in molecular clouds, with silicon monoxide (SiO) particularly useful in detecting the presence of shock waves.Using ALMA’s high resolution and sensitivity to map distinct spectral lines within the molecular clouds at the center of the Milky Way, the team led by Kai Yang (Shanghai Jiao Tong University) has delineated a new type of long, narrow filamentary structure at a significantly finer scale. The dynamic interaction between this turbulent environment and the slim filaments produced as shocks ripple through provides a more complete view of the cyclical processes within the CMZ. Yang’s team reports it remains unknown how these slim filaments initially arise, but shock processes emerge as a likely explanation.More info at <a href="https://www.almaobservatory.org/en/press-releases/alma-discovers-space-tornadoes-around-the-milky-ways-core/" rel="nofollow noopener" translate="no" target="_blank">https://www.almaobservatory.org/en/press-releases/alma-discovers-space-tornadoes-around-the-milky-ways-core/</a><a href="https://astrodon.social/tags/ALMA" class="mention hashtag" rel="nofollow noopener" target="_blank">#ALMA</a> <a href="https://astrodon.social/tags/AtacamaLargeMillimeterSubmillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterSubmillimeterArray</a> <a href="https://astrodon.social/tags/AtacamaLargeMillimeterArray" class="mention hashtag" rel="nofollow noopener" target="_blank">#AtacamaLargeMillimeterArray</a> <a href="https://astrodon.social/tags/MilkyWay" class="mention hashtag" rel="nofollow noopener" target="_blank">#MilkyWay</a> <a href="https://astrodon.social/tags/CMZ" class="mention hashtag" rel="nofollow noopener" target="_blank">#CMZ</a> <a href="https://astrodon.social/tags/CentralMolecularZone" class="mention hashtag" rel="nofollow noopener" target="_blank">#CentralMolecularZone</a> <a href="https://astrodon.social/tags/SgrA" class="mention hashtag" rel="nofollow noopener" target="_blank">#SgrA</a>* <a href="https://astrodon.social/tags/GalacticCenter" class="mention hashtag" rel="nofollow noopener" target="_blank">#GalacticCenter</a>

Dr. Juande Santander-VelaGalaxy clusters are the largest structures in the universe. Protoclusters like SPT2349-56 offer a unique window into this process, allowing astronomers to observe galaxies as they come together in a dense environment. By comparing ALMA's high-resolution configuration observations with lower-resolution data from ALMA's Compact Array (ACA), and APEX, the team found a significant amount of molecular gas "invisible" in the higher-resolution ALMA images. The ACA detected 75% more CO than the sum of individual sources detected in higher-resolution ALMA data. This missing gas isn't just a few faint, undetected galaxies. Instead, it appears to be a diffuse reservoir of gas spread throughout the protocluster. This hidden gas reservoir could be the key to understanding the intense star formation activity observed in SPT2349-56. The presence of so much extra gas extends the star formation fuel, meaning the overall depletion timescale will exceed 400 million years. SPT2349-56 is an extreme system, producing stars 10.000 times faster than our Milky Way, and these observations have pushed scientists' understanding of galaxy formation and evolution. No simulation or galaxy formation model had previously predicted this overdensity of gas. These findings also suggest that high-resolution ALMA observations, while excellent for studying individual galaxies, may miss a significant gas component in these early clusters. The missing gas may reside in the circum-galactic medium (CGM) or the pre-heated proto-intracluster medium (proto-ICM).
