Weighing the Milky Way and Andromeda with Artificial Intelligence
Pablo Villanueva-Domingo, Francisco Villaescusa-Navarro, Shy Genel +6
We present new constraints on the masses of the halos hosting the Milky Way and Andromeda galaxies derived using graph neural networks. Our models, trained on thousands of state-of…
Supermassive black holes in cosmological simulations II: the AGN population and predictions for upcoming X-ray missions
Melanie Habouzit, Rachel S. Somerville, Yuan Li +13
In large-scale hydrodynamical cosmological simulations, the fate of massive galaxies is mainly dictated by the modeling of feedback from active galactic nuclei (AGN). The amount of…
From EMBER to FIRE: predicting high resolution baryon fields from dark matter simulations with Deep Learning
Mauro Bernardini, Robert Feldmann, Daniel Anglés-Alcázar +4
Hydrodynamic simulations provide a powerful, but computationally expensive, approach to study the interplay of dark matter and baryons in cosmological structure formation. Here we…
HIFlow: Generating Diverse HI Maps and Inferring Cosmology while Marginalizing over Astrophysics using Normalizing Flows
Sultan Hassan, Francisco Villaescusa-Navarro, Benjamin Wandelt +11
A wealth of cosmological and astrophysical information is expected from many ongoing and upcoming large-scale surveys. It is crucial to prepare for these surveys now and develop to…
Multifield Cosmology with Artificial Intelligence
Francisco Villaescusa-Navarro, Daniel Anglés-Alcázar, Shy Genel +10
Astrophysical processes such as feedback from supernovae and active galactic nuclei modify the properties and spatial distribution of dark matter, gas, and galaxies in a poorly und…
Running Late: Testing Delayed Supermassive Black Hole Growth Models Against the Quasar Luminosity Function
Megan Taylor Tillman, Sarah Wellons, Claude-André Faucher-Giguère +2
Observations of massive galaxies at low redshift have revealed approximately linear scaling relations between the mass of a supermassive black hole (SMBH) and properties of its hos…
The origin of galaxy colour bimodality in the scatter of the Stellar-to-Halo Mass Relation
Weiguang Cui, Romeel Davé, John A. Peacock +2
Recent observations reveal that, at a given stellar mass, blue galaxies tend to live in haloes with lower mass while red galaxies live in more massive host haloes. The physical dri…
IQ Collaboratory III: The Empirical Dust Attenuation Framework -- Taking Hydrodynamical Simulations with a Grain of Dust
ChangHoon Hahn, Tjitske K. Starkenburg, Daniel Anglés-Alcázar +8
We present the Empirical Dust Attenuation (EDA) framework -- a flexible prescription for assigning realistic dust attenuation to simulated galaxies based on their physical properti…
Which AGN Jets Quench Star Formation in Massive Galaxies?
Kung-Yi Su, Philip F. Hopkins, Greg L. Bryan +12
Without additional heating, radiative cooling of gas in the halos of massive galaxies (Milky Way and above) produces cold gas or stars in excess of that observed. Previous work sug…
