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…

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…

Euclid. I. Overview of the Euclid mission

Euclid Collaboration, Y. Mellier, Abdurro'uf +1134

The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Eucl…

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}^…

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…

Obscuration beyond the nucleus: infrared quasars can be buried in extreme compact starbursts

Carolina Andonie, David M. Alexander, Claire Greenwell +14

In the standard quasar model, the accretion disk obscuration is due to the canonical dusty torus. Here, we argue that a substantial part of the quasar obscuration can come from the…
