How galaxies acquire their stellar mass at high redshift: High star formation efficiencies and the relative roles of dust and initial mass function

Hao Fu, Francesco Shankar, Fabio Fontanot +9

JWST has measured an unprecedented abundance of galaxies above , whose formation and evolution are still difficult to reconcile within traditional galaxy evolution mo…

Too many or too massive? Investigating the high- demography of active SMBHs from JWST

Daniel Roberts, Francesco Shankar, Vieri Cammelli +12

Recent JWST observations have unveiled a numerous population of low-luminosity active galactic nuclei (AGN) at , with space densities roughly an order of magnitude above p…

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…

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…

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…

Probing the co-evolution of SMBHs and their hosts from scaling relations pairwise residuals: dominance of stellar velocity dispersion and host halo mass

Francesco Shankar, Mariangela Bernardi, Daniel Roberts +17

The correlations between Supermassive Black Holes (SMBHs) and their host galaxies still defy our understanding from both the observational and theoretical perspectives. Here we per…
