Fuelling the central region of galaxies with misaligned gas accretion
J. L. Tous, S. I. Raimundo, R. Riffel +3
Recent studies have shown that the accretion of kinematically misaligned gas fuels the central reservoir of galaxies, triggering nuclear activity and star formation. In this work,…
The role of black hole feedback on galaxy star formation and the degeneracy with halo quenching
Hao Fu, Francesco Shankar, Feng Yuan +9
The interplay between the accretion of supermassive black holes (SMBHs) and the stellar mass growth of the host galaxies is still a matter of hot debate. The accretion of the SMBHs…

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…
Shedding light on the star formation rate-halo accretion rate connection and halo quenching mechanism via DECODE, the Discrete statistical sEmi-empiriCal mODEl
Hao Fu, Lumen Boco, Francesco Shankar +9
Aims: The relative roles of the physical mechanisms involved in quenching galaxy star formation are still unclear. We tackle this fundamental problem with our cosmological semi-emp…
Semi-empirical Models of Galaxy Formation and Evolution

We provide a review on semi-empirical models of galaxy formation and evolution. We present a brief census of the three main modeling approaches to galaxy evolution, namely hydrodyn…
Investigating the effects of fresh gas on the Active Galactic Nuclei luminosity of early- and late-type galaxies
Martyna W. Winiarska, Sandra I. Raimundo, Timothy A. Davis +3
The main fuelling processes for Active Galactic Nuclei (AGN) are currently unknown. Previous work showed that galaxies with a large kinematic misalignment between their stellar and…
Unveiling the (in)consistencies among the galaxy stellar mass function, star formation histories, satellite abundances and intracluster light from a semi-empirical perspective
Hao Fu, Francesco Shankar, Mohammadreza Ayromlou +16
In a hierarchical, dark matter-dominated Universe, stellar mass functions (SMFs), galaxy merger rates, star formation histories (SFHs), satellite abundances, and intracluster light…
Non-Monotonic Relations of Galaxy Star Formation, Radius, and Structure at Fixed Stellar Mass
Jimena Stephenson, Aldo Rodriguez-Puebla, S. M. Faber +9
We investigate the relation between galaxy structure and star formation rate (SFR) in a sample of central galaxies with and axial ratios .…
Scrutinising evidence for the triggering of Active Galactic Nuclei in the outskirts of massive galaxy clusters at
Iván Muñoz Rodríguez, Antonis Georgakakis, Francesco Shankar +6
Environmental effects are believed to play an important yet poorly understood role in triggering accretion events onto the supermassive black holes (SMBHs) of galaxies (Active Gala…
Accretion properties of X-ray AGN: Evidence for radiation-regulated obscuration with redshift-dependent host galaxy contribution
Brivael Laloux, Antonis Georgakakis, David M. Alexander +12
We adopt a Bayesian X-ray spectral approach to investigate the accretion properties of unobscured () and obscured ($22< \log(N_{\rm H}/{\rm cm}^…
A post-merger enhancement only in star-forming Type 2 Seyfert galaxies: the deep learning view
M. S. Avirett-Mackenzie, C. Villforth, M. Huertas-Company +7
Supermassive black holes require a reservoir of cold gas at the centre of their host galaxy in order to accrete and shine as active galactic nuclei (AGN). Major mergers have the ab…
Probing the roles of orientation and multi-scale gas distributions in shaping the obscuration of Active Galactic Nuclei through cosmic time
Alba V. Alonso-Tetilla, Francesco Shankar, Fabio Fontanot +14
The origin of obscuration in Active Galactic Nuclei (AGN) is still an open debate. In particular, it is unclear what drives the relative contributions to the line-of-sight column d…
