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…
Super-resolution simulation of the Fuzzy Dark Matter cosmological model
Meris Sipp, Patrick LaChance, Rupert Croft +2
AI super-resolution, combining deep learning and N-body simulations has been shown to successfully reproduce the large scale structure and halo abundances in the Lambda Cold Dark M…
Orbital and Radiative Properties of Wandering Intermediate-Mass Black Holes in the ASTRID Simulation
Emma Jane Weller, Fabio Pacucci, Yueying Ni +4
Intermediate-Mass Black Holes (IMBHs) of are commonly found at the center of dwarf galaxies. Simulations and observations convincingly show that a sizable po…
Robust field-level inference with dark matter halos
Helen Shao, Francisco Villaescusa-Navarro, Pablo Villanueva-Domingo +13
We train graph neural networks on halo catalogues from Gadget N-body simulations to perform field-level likelihood-free inference of cosmological parameters. The catalogues contain…
Ultramassive black holes formed by triple quasar mergers at
Yueying Ni, Tiziana DiMatteo, Nianyi Chen +2
The origin of rare and elusive ultramassive black holes (UMBH, with MBH > 1e10 Msun) is an open question. Using the large volume cosmological hydrodynamic simulation ASTRID, we rep…
Statistics of Galactic-Scale Quasar Pairs at Cosmic Noon
Yue Shen, Hsiang-Chih Hwang, Masamune Oguri +8
The statistics of galactic-scale quasar pairs can elucidate our understanding of the dynamical evolution of supermassive black hole (SMBH) pairs, the duty cycles of quasar activity…
Properties and Evolution of Dual and Offset AGN in the ASTRID Simulation at
Nianyi Chen, Tiziana Di Matteo, Yueying Ni +7
We examine the dual (both BHs active) and offset (one BH active) AGN population (comprising 2000 pairs at ) at in the AS…
The BlueTides Mock Image Catalogue: Simulated observations of high-redshift galaxies and predictions for JWST imaging surveys
Madeline A. Marshall, Katelyn Watts, Stephen Wilkins +7
We present a mock image catalogue of ~100,000 MUV=-22.5 to -19.6 mag galaxies at z=7-12 from the BlueTides cosmological simulation. We create mock images of each galaxy with the Ja…
Probing the quasars in a universe with IllustrisTNG physics: Impact of gas-based black hole seeding models
Aklant Kumar Bhowmick, Laura Blecha, Yueying Ni +6
We explore implications of a range of black hole (BH) seeding prescriptions on the formation of the brightest quasars in cosmological hydrodynamic simulations. The unde…
The CAMELS project: public data release
Francisco Villaescusa-Navarro, Shy Genel, Daniel Anglés-Alcázar +44
The Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) project was developed to combine cosmology with astrophysics through thousands of cosmological hydrodynami…
