A vast population of wandering and merging IMBHs at cosmic noon
Tiziana Di Matteo, Yueying Ni, Nianyi Chen +5
Massive black holes in the centers of galaxies today must have grown by several orders of magnitude from seed black holes formed at early times. Detecting a population of intermedi…
Mocking Faint Black Holes during Reionization
Marius B. Eide, Benedetta Ciardi, Yu Feng +1
To investigate the potential abundance and impact of nuclear black holes (BHs) during reionization, we generate a neural network that estimates their masses and accretion rates by…
Large scale simulations of H and He reionization and heating driven by stars and more energetic sources
Marius B. Eide, Benedetta Ciardi, Luca Graziani +3
We present simulations of cosmic reionization and reheating from to , investigating the role of stars (emitting soft UV-photons), nuclear black holes (BHs, with power-l…
Group-scale intrinsic galaxy alignments in the Illustris-TNG and MassiveBlack-II simulations
Ananth Tenneti, Thomas D. Kitching, Benjamin Joachimi +1
We study the alignments of satellite galaxies, and their anisotropic distribution, with respect to location and orientation of their host central galaxy in MassiveBlack-II and Illu…
The host galaxies of z=7 quasars: predictions from the BlueTides simulation
Madeline A. Marshall, Yueying Ni, Tiziana Di Matteo +4
We examine the properties of the host galaxies of quasars using the large volume, cosmological hydrodynamical simulation BlueTides. We find that the 10 most massive black hol…
Cosmic variance of galaxies: Prediction from BlueTides
Aklant K. Bhowmick, Rachel S. Somerville, Tiziana DiMatteo +3
In the coming decade, a new generation of telescopes, including JWST and WFIRST, will probe the period of the formation of first galaxies and quasars, and open up the last frontier…
The early growth of supermassive black holes in cosmological hydrodynamic simulations with constrained Gaussian realizations
Kuan-Wei Huang, Yueying Ni, Yu Feng +1
The paper examines the early growth of supermassive black holes (SMBHs) in cosmological hydrodynamic simulations with different BH seeding scenarios. Employing the constrained Gaus…
The evolution of galaxy intrinsic alignments in the MassiveBlack II universe
Aklant K Bhowmick, Yingzhang Chen, Ananth Tenneti +2
We investigate the redshift evolution of the intrinsic alignments (IA) of galaxies in the \texttt{MassiveBlackII} (MBII) simulation. We select galaxy samples above fixed subhalo ma…
Multiplicity functions of quasars: Predictions from the MassiveBlackII simulation
Aklant K. Bhowmick, Tiziana Di Matteo, Adam D. Myers
We examine multiple AGN systems (triples and quadruples, in particular) in the \texttt{MassiveBlackII} simulation over a redshift range of . We identify…
A tiny host galaxy for the first giant black hole: quasar in BlueTides
Ananth Tenneti, Stephen M. Wilkins, Tiziana Di Matteo +2
The most distant known quasar recently discovered by Bañados et al. (2018) is at (690 Myr after the Big Bang), at the dawn of galaxy formation. We explore the host galaxy o…
Gas outflows from the z= 7.54 quasar : predictions from the BlueTides Simulation
Yueying Ni, Tiziana Di Matteo, Yu Feng +2
Many theoretical models predict that quasar driven outflows account for the observed quenching of star formation in massive galaxies. There is growing observational evidence for qu…
