Modeling the HI-Halo Connection: Evolution, Scatter, and a Halo-based Prescription for 21-cm Mock Catalogs
Mohd Kamran, Gabriella De Lucia, Marta Spinelli +3
The redshifted 21-cm line of neutral hydrogen (HI) is a powerful tracer of large-scale structure, and post-reionization HI intensity mapping is emerging as a competitive cosmologic…
Star formation powers optical line emission from the CGM

Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line…
Mechanisms Affecting Galaxies Nearby and Environmental Trends (MAGNET)
Benedetta Vulcani, Gabriella De Lucia, Daria Zakharova +28
[ABRIDGED] Galaxy evolution is shaped by internal and external mechanisms that regulate the baryon cycle and star formation activity. We present a theoretical framework based on th…
Characterizing the roles of transitory obscured phases and inner torus in shaping the fractions of obscured AGN at cosmic noon
Alba V. Alonso-Tetilla, Francesco Shankar, Fabio Fontanot +11
The origin of obscuration in Active Galactic Nuclei (AGN) is still a matter of contention. It is unclear whether obscured AGN are primarily due to line-of-sight effects, a transito…
The clustering of C IV and Si IV at the end of reionisation: A perspective from the E-XQR-30 survey
Louise Welsh, Valentina D'Odorico, Fabio Fontanot +14
We aim to study the clustering of metal absorption lines and the structures that they arise in as a function of cosmic time. We focus on C IV and Si IV absorption features that are…
The impact of ram pressure on cluster galaxies, insights from GAEA and TNG
Lizhi Xie, Gabriella De Lucia, Matteo Fossati +2

The Charting Cluster Construction with VUDS and ORELSE (C3VO) survey is an ongoing imaging and spectroscopic campaign aiming to map out the growth of structure up to and w…
The diverse star formation histories of early massive, quenched galaxies in modern galaxy formation simulations
Claudia del P. Lagos, Francesco Valentino, Ruby J. Wright +13
We present a comprehensive study of the star formation histories of massive-quenched galaxies at in 3 semi-analytic models (SHARK, GAEA, GALFORM) and 3 cosmological hydrodyna…
The formation of supermassive black holes from Population III.1 seeds. III. Galaxy evolution and black hole growth from semi-analytic modelling
Vieri Cammelli, Pierluigi Monaco, Jonathan C. Tan +5
We present an implementation of Pop III.1 seeding of supermassive black holes (SMBHs) in a theoretical model of galaxy formation and evolution to assess the growth the SMBH populat…
The first quenched galaxies, when and how?
Lizhi Xie, Gabriella De Lucia, Fabio Fontanot +11
Many quiescent galaxies discovered in the early Universe by \textit{JWST} raise fundamental questions on when and how these galaxies became and stayed quenched. Making use of the l…
Environmental effects on satellite galaxies from the perspective of cold gas
Hongxing Chen, Lizhi Xie, Jie Wang +4
Environment plays a pivotal role in shaping the evolution of satellite galaxies. Analyzing the properties related to the cold gas phase of satellites provides insights into unravel…

Daria Zakharova, Benedetta Vulcani, Gabriella De Lucia +3
Filaments are elongated structures that connect groups and clusters of galaxies and are visually the striking feature in cosmological maps. In the literature, typically filaments a…
