Black hole merger rates for LISA and LGWA from semi-analytical modelling of light seeds
Jasbir Singh, Paola Severgnini, Vieri Cammelli +10
With the upcoming space- and Moon-based gravitational-wave detectors, LISA and LGWA respectively, a new era of GW astronomy will begin with the possibility of detections of the mer…
Glimmers in the Cosmic Dawn. III. On the Photometrically Determined Black Hole Mass to Stellar Mass Relation Across Cosmic Time
Alice R. Young, Matthew J. Hayes, Alberto Saldana-Lopez +7
We present the results from performing spectral energy distribution (SED) fitting on 121 variable active galactic nuclei (AGN) candidates in the Hubble Ultra Deep Field (HUDF) usin…
Glimmers in the Cosmic Dawn. II. A variability census of supermassive black holes across the Universe
Vieri Cammelli, Jonathan C. Tan, Alice R. Young +7
Understanding the origin and evolution of supermassive black holes (SMBH) stands as one of the most important challenges in astrophysics and cosmology, with little current theoreti…
The Emergence and Ionizing Feedback of Pop III.1 Stars as Progenitors for Supermassive Black Holes
Mahsa Sanati, Jonathan C. Tan, Julien Devriendt +9
Recent observations by JWST reveal an unexpectedly abundant population of rapidly growing supermassive black holes (SMBHs) in the early Universe, underscoring the need for improved…
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…
