Effects of multi-channel AGN feedback in FIRE cosmological simulations of massive galaxies
Lindsey Byrne, Claude-André Faucher-Giguère, Sarah Wellons +6
Feedback from supermassive black holes is believed to be a critical driver of the observed color bimodality of galaxies above the Milky Way mass scale. AGN feedback has been modele…
The Last Journey. II. SMACC -- Subhalo Mass-loss Analysis using Core Catalogs
Imran Sultan, Nicholas Frontiere, Salman Habib +4
This paper introduces SMACC -- Subhalo Mass-loss Analysis using Core Catalogs. SMACC adds a mass model to substructure merger trees based on halo "core tracking." Our approach avoi…
Cold vs. Hot Gas Accretion and Angular Momentum in FIRE Simulations: From Halo to Galaxy Scales
Imran Sultan, Claude-André Faucher-Giguère, Jonathan Stern +1
We present a systematic study of gas accretion and angular momentum in the circumgalactic medium (CGM) using high-resolution FIRE cosmological simulations. Our analysis includes ha…
Ne VIII in the warm-hot circumgalactic medium of FIRE simulations and in observations
Nastasha A. Wijers, Claude-André Faucher-Giguère, Jonathan Stern +2
The properties of warm-hot gas around galaxies can be studied with absorption lines from highly ionized metals. We predict Ne VIII column densities from cosmological z…
Cooling Flows as a Reference Solution for the Hot Circumgalactic Medium
Imran Sultan, Claude-André Faucher-Giguère, Jonathan Stern +3
The circumgalactic medium (CGM) in halos is dominated by a hot phase ( K). While many models exist for the hot gas structur…
Hot accretion onto spiral galaxies: the origin of extended and warped HI discs
Sriram Sankar, Jonathan Stern, Chris Power +6
Gas accretion, hot ( K) atmospheres, and a tilt between the rotation axes of the disc and the atmosphere are all common predictions of standard galaxy evolution theory f…
Farpoint: A High-Resolution Cosmology Simulation at the Gigaparsec Scale
Nicholas Frontiere, Katrin Heitmann, Esteban Rangel +7
In this paper we introduce the Farpoint simulation, the latest member of the Hardware/Hybrid Accelerated Cosmology Code (HACC) gravity-only simulation family. The domain covers a v…
The Last Journey. I. An Extreme-Scale Simulation on the Mira Supercomputer
Katrin Heitmann, Nicholas Frontiere, Esteban Rangel +10
The Last Journey is a large-volume, gravity-only, cosmological N-body simulation evolving more than 1.24 trillion particles in a periodic box with a side-length of 5.025Gpc. It was…
