#18giugno Giornata internazionale contro i discorsi d'odio

Massimo Palermo su #LCdM confronta l' #ingiuria in testi toscani medievali e in alcuni discorsi di #odio in #rete. Emergono da un lato differenze tra le ingiurie medievali e gli insulti sui #social #media, dovuti in primo luogo alle differenze di medium e di contesto comunicativo; dall’altro una certa stabilità degli ambiti semantici dell’offesa nel tempo.

Here is a new review paper that I am also part of on the tensions in cosmology:
arxiv.org/abs/2504.01669

As one of my dear collaborators phrased it: 500+ authors wrote 400+ pages on the issues with the cosmological concordance model. So can we still say that LCDM is fine?!
I also contributed because I think that the sum of all issues should make us rethink the 100-yo model.

arXiv.orgThe CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physicsThe standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades. This concordance model is constructed by a universal cosmological constant and supported by a matter sector described by the standard model of particle physics and a cold dark matter contribution, as well as very early-time inflationary physics, and underpinned by gravitation through general relativity. There have always been open questions about the soundness of the foundations of the standard model. However, recent years have shown that there may also be questions from the observational sector with the emergence of differences between certain cosmological probes. In this White Paper, we identify the key objectives that need to be addressed over the coming decade together with the core science projects that aim to meet these challenges. These discordances primarily rest on the divergence in the measurement of core cosmological parameters with varying levels of statistical confidence. These possible statistical tensions may be partially accounted for by systematics in various measurements or cosmological probes but there is also a growing indication of potential new physics beyond the standard model. After reviewing the principal probes used in the measurement of cosmological parameters, as well as potential systematics, we discuss the most promising array of potential new physics that may be observable in upcoming surveys. We also discuss the growing set of novel data analysis approaches that go beyond traditional methods to test physical models. [Abridged]

Tanto si parla in questi giorni di #Biancaneve, con l’uscita del discusso remake della #Disney, dove i sette #nani non solo sono scomparsi dal titolo, ma hanno anche perso la loro dimensione fisica.
Niente più attori nani in carne e ossa, bensì personaggi creati con la #AI.

Anche in questo articolo di #LCdM è protagonista la favola di Biancaneve, che, nella versione animata, ha visto evolversi il suo #linguaggio in uno stile più vicino ai ragazzi degli anni '80.

#17gennaio Giornata del #dialetto

"Travolta da un insolito destino: la lingua filmata nell'azzurro mare del cinema, oggi"

Con questo articolo #OpenAccess, #LCdM esamina i vari dialetti rappresentati nel #cinemaitaliano contemporaneo, come conseguenza della multispazialità e #plurilinguismo che caratterizzano la nostra produzione cinematografica dagli anni Novanta ad oggi.

Nella polemica sul #capodanno romano dovuta al ritiro dell'invito al #trapper #TonyEffe per i suoi testi misogini, colpisce la sua difesa da parte delle artiste donne.
Un articolo #OpenAccess di #LCdM sulla #musica #rap e #trap femminile esamina la posizione delle #cantanti sugli #stereotipi di #genere: le artiste si oppongono alla narrazione della #donna che si fa nella trap o la accolgono e la fanno propria?

Il #25Novembre si celebra la giornata internazionale per l'eliminazione della #violenza contro le #donne. Partecipiamo alla sensibilizzazione su questo tema purtroppo sempre più attuale, con un articolo della rivista #LCdM. Lo studio riflette sul ruolo del #linguaggio dei #media e su come questo si configuri quale strumento per la comprensione degli assunti ideologici che stanno dietro la narrazione della violenza di #genere e dei #femminicidi nella #stampa italiana⬇️

Congratulations Stacy McGaugh @DudeDarkmatter et al. for the paper in ApJ:
"Accelerated Structure Formation: The Early Emergence of Massive Galaxies and Clusters of Galaxies"
🔗iopscience.iop.org/article/10.

#MOND may be a phenomenological dinghy, but cosmologists would rather stay on the ΛCDM-Titanic because it is unsinkable!

Good thing I am not a cosmologist😉

It's going to take more than early dark energy to resolve the #Hubble tension.

Our best understanding of the #universe is rooted in a cosmological model known as #LCDM — the Lambda Cold Dark Matter model.

Although the LCDM model matches our observations incredibly well, it isn't perfect. And the more data we gather on the early universe, the less perfect it seems to be.

Last but not least, a new measurement of the Hubble Constant is obtained by analyzing the geometrical properties of Ho'oleilana: 76.9 (+8.2)(-4.8) km/s /Mpc

This value is consistent with other direct local probes, and further exacerbates the "Hubble tension" in the ΛCDM model.
