The Euclid mission's inaugural Quick Data Release (Q1) marks a significant milestone in our quest to understand the universe's structure and evolution. In this talk, I will present a broad overview of the Q1 science results, highlighting early achievements in galaxy evolution, large-scale structure, strong lensing and active galactic nuclei (AGN). These findings not only validate Euclid's...
Tra le molteplici domande affrontate dall'astrofisica, quelle che si interrogano sull'origine, la composizione e l'evoluzione dell'Universo sulle scale spaziali e temporali più grandi tendono a suscitare grande interesse da parte del pubblico, facendo della cosmologia uno degli argomenti più gettonati sulle pagine scientifiche di riviste e quotidiani. La missione Euclid dell'Agenzia Spaziale...
Nel talk presenterò una overview dei primi 3 anni di studio dei dati ottenuti con JWST (con particolare attenzione al ruolo di primo piano ricoperto da ricercatrici e ricercatori INAF), dati che hanno rivoluzionato l'astrofisica extragalattica consentendoci di scoprire molte caratteristiche sorprendenti dell'Universo primordiale e dei meccanismi di formazione delle prime galassie e strutture...
Robust distance estimates are crucial for interpreting observational results. They are necessary to map the Universe, constrain physical properties of galaxies, and can be used to test tensions in the Hubble constant. In the nearby Universe, where peculiar velocities dominate, there is a specific need for redshift-independent distances. Surface brightness fluctuations (SBF) can be used to...
"Early results from JWST have provided new challenges to our understanding of early galaxy formation. In particular, the abundance and inferred physical properties of $z\gtrsim7$ galaxies suggest potentially significant tensions with predictions from the standard ΛCDM cosmological model.
In my work (Cantarella et al., in preparation), we take advantage of the latest version of the GAEA galaxy...
Dark matter (DM), a large (~85%) non-baryonic and non-relativistic component of the matter density of the Universe, likely consists of one or several so-far undetected particles hypothesized in theories beyond the Standard Model (SM). One of the most promising approaches to shed light on the nature of DM particles is to search for signatures of their annihilation or decay into SM particles...
"The frontier of the new generation of all-sky surveys is to explore the Universe down to the low-surface brightness (LSB) regime, where highly diagnostic relics of the galaxy mass assembly across all environments reside. The primary objective is to map the mass assembly of galaxies in all environments, thereby constraining their formation and evolution within the Lambda-Cold Dark Matter...
