The formation of supermassive black holes from Population III.1 seeds. IV. Self-regulated seeding from supermassive star ionizing feedback
Maya A. Petkova, Jonathan C. Tan, Jasbir Singh +5
Supermassive Population III.1 stars, i.e., formed from pristine, metal-free gas leading to conditions where dark matter annihilation heating is significant, have been proposed as t…
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…
The Origin of Supermassive Black Holes from Pop III.1 Seeds
Jonathan C. Tan, Jasbir Singh, Vieri Cammelli +4
The origin of supermassive black holes (SMBHs) is a key open question for contemporary astrophysics and cosmology. Here we review the features of a cosmological model of SMBH forma…
Glimmers in the Cosmic Dawn: A Census of the Youngest Supermassive Black Holes by Photometric Variability
Matthew J. Hayes, Jonathan C. Tan, Richard S. Ellis +10
We report first results from a deep near infrared campaign with the Hubble Space Telescope to obtain late-epoch images of the Hubble Ultra-Deep Field (HUDF), 10-15 years after the…
