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…
Optically thick winds of very massive stars suppress intermediate-mass black hole formation
Stefano Torniamenti, Michela Mapelli, Lumen Boco +3
Intermediate-mass black holes (IMBHs) are the link between stellar-mass and supermassive black holes. Gravitational waves have started unveiling a population of IMBHs in the $\sim…
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…
Cosmography via stellar archaeology of low-redshift early-type galaxies from SDSS
Carlos A. Álvarez, Marcos M. Cueli, Alessandro Bressan +5
Cosmic chronometers offer a model-independent way to trace the expansion history of the Universe via the dating of passively evolving objects. This enables testing the validity of…
Semi-empirical Framework of Supermassive Black Hole Evolution: Highlighting a possible tension between Demographics and Gravitational Wave Background
Andrea Lapi, Francesco Shankar, Michele Bosi +4
The evolution of the supermassive Black Hole (BH) population across cosmic times remains a central unresolved issue in modern astrophysics, due to the many noticeable uncertainties…
Metal-poor single Wolf-Rayet stars: The interplay of optically thick winds and rotation
Lumen Boco, Michela Mapelli, Andreas A. C. Sander +7
The Small Magellanic Cloud (SMC) hosts 12 known Wolf-Rayet (WR) stars, seven of which are apparently single. Their formation is a challenge for current stellar evolution models bec…
