The extragalactic science of the KMOS VVVX-GalCen spectroscopic survey II: Discovery of a galaxy cluster at z = 0.089 behind the Galactic plane

E. O. Schmidt, C. Valotto, C. Villalon +33

The Zone of Avoidance (ZoA) continues to represent the most significant incompleteness in the extragalactic census of the Local Universe. It is evident that photometric surveys alo…

Probing the faint end of simulated galaxy counts at z>3

Flaminia Fortuni, Emiliano Merlin, Marco Castellano +2

Simulations and observations now probe comparable redshift regimes with unprecedented accuracy, enabling direct consistency tests through forward modeling. In a previous work, we i…

Picture an Astronomer: Best Practices for Retaining Talent in Astrophysics

Ava Polzin, Katherine E. Whitaker, C. Megan Urry +85

Women are consistently underrepresented in astrophysics yet are simultaneously subject to disproportionate attrition at every career stage. This disparity between demonstrated effi…

The Early Maturity of High-Redshift Galaxies: Insights from sSFR, M/L and SFHs at z~7-14

P. Santini, M. Castellano, A. Calabrò +23

The James Webb Space Telescope (JWST) has revealed an unexpected excess of UV-bright galaxies at z>10, unaccounted for by extrapolations from pre-JWST observations and theoretical…

Witnessing downsizing in the making: quiescent and breathing galaxies at the dawn of the Universe

Emiliano Merlin, Flaminia Fortuni, Antonello Calabrò +18

[Shortened for arXiv] We conduct a systematic search for quiescent galaxies at in six extragalactic deep fields observed with NIRCam, with t…

ASTRODEEP-JWST: NIRCam-HST multiband photometry and redshifts for half a million sources in six extragalactic deep fields

E. Merlin, P. Santini, D. Paris +52

We present a set of photometric catalogs primarily aimed at providing the community with a comprehensive database for the study of galaxy populations in the high redshift Universe.…

Cosmic Evolution Early Release Science (CEERS) survey: The colour evolution of galaxies in the distant Universe

Stephen M. Wilkins, Jack C. Turner, Micaela B. Bagley +20

The wavelength-coverage and sensitivity of JWST now enables us to probe the rest-frame UV - optical spectral energy distributions (SEDs) of galaxies at high-redshift (). From…

FORECAST: a flexible software to forward model cosmological hydrodynamical simulations mimicking real observations

Flaminia Fortuni, Emiliano Merlin, Adriano Fontana +7

We present FORECAST, a new flexible and adaptable software package that performs forward modeling of the output of any cosmological hydrodynamical simulations to create a wide rang…

Early Results from GLASS-JWST. XIX: A High Density of Bright Galaxies at in the Abell 2744 Region

Marco Castellano, Adriano Fontana, Tommaso Treu +38

We report the detection of a high density of redshift galaxies behind the foreground cluster Abell 2744, selected from imaging data obtained recently with NIRCam onbo…

First Light And Reionisation Epoch Simulations (FLARES) VIII. The Emergence of Passive Galaxies at

Christopher C. Lovell, Will Roper, Aswin P. Vijayan +9

Passive galaxies are ubiquitous in the local universe, and various physical channels have been proposed that lead to this passivity. To date, robust passive galaxy candidates have…

The Stellar Mass Function in CANDELS and Frontier Fields: the build-up of low mass passive galaxies since z~3

P. Santini, M. Castellano, A. Fontana +8

Despite significant efforts in the recent years, the physical processes responsible for the formation of passive galaxies through cosmic time remain unclear. The shape and evolutio…

The ASTRODEEP-GS43 catalogue: new photometry and redshifts for the CANDELS GOODS-South field

E. Merlin, M. Castellano, P. Santini +17

We present ASTRODEEP-GS43, a new multiwavelength photometric catalogue of the GOODS-South field, which builds and improves upon the previously released CANDELS catalogue. We provid…

The emergence of passive galaxies in the early Universe

P. Santini, M. Castellano, E. Merlin +10

The emergence of passive galaxies in the early Universe results from the interplay among the processes responsible for their rapid assembly and for the abrupt shut-down of their SF…

Constraints on Dynamical Dark Energy Models from the Abundance of Massive Galaxies at High Redshifts

N. Menci, A. Grazian, M. Castellano +9

We compare the maximal abundance of massive systems predicted in different dynamical dark energy (DDE) models at high redshifts z = 4-7 with the measured abundance of the most mass…

Red & Dead CANDELS: massive passive galaxies at the dawn of the Universe

E. Merlin, F. Fortuni, M. Torelli +7

We search the five CANDELS fields (COSMOS, EGS, GOODS-North, GOODS-South and UDS) for passively evolving a.k.a. "red and dead" massive galaxies in the first 2 Gyr after the Big Ban…
