The Clustering of Undetected High-redshift Black Holes and Their Signatures in Cosmic Backgrounds
Angelo Ricarte, Fabio Pacucci, Nico Cappelluti +1
There exist hitherto unexplained fluctuations in the Cosmic Infrared Background (CIB) on arcminute scales and larger. These have been shown to cross-correlate with the Cosmic X-ray…
Disentangling nature from nurture: tracing the origin of seed black holes
Priyamvada Natarajan, Angelo Ricarte, Vivienne Baldassare +16
The origin and properties of black hole seeds that grow to produce the detected population of supermassive black holes are unconstrained at present. Despite the existence of severa…
Tracing Black Hole and Galaxy Co-evolution in the Romulus Simulations
Angelo Ricarte, Michael Tremmel, Priyamvada Natarajan +1
We study the link between supermassive black hole growth and the stellar mass assembly of their host galaxies in the state-of-the-art Romulus suite of simulations. The cosmological…
Electromagnetic Window into the Dawn of Black Holes
Zoltán Haiman, William N. Brandt, Alexey Vikhlinin +28
Massive 10^6-10^10 Msun black holes (BHs) are ubiquitous in local galactic nuclei. They were common by the time the Universe is several Gyr old, and many of them were in place with…
