Observational Signatures of AGN Feedback in the Morphology and the Ionization States of Milky Way-like Galaxies
Nadia Qutob, Razieh Emami, Kung-Yi Su +24
We make an in-depth analysis of different AGN jet models' signatures, inducing quiescence in galaxies with a halo mass of . Three jet models, including cosmic ray-…
Unraveling Jet Quenching Criteria Across L* Galaxies and Massive Cluster Ellipticals
Kung-Yi Su, Greg L. Bryan, Christopher C. Hayward +8
In the absence of supplementary heat, the radiative cooling of halo gas around massive galaxies (Milky Way mass and above) leads to an excess of cold gas or stars beyond observed l…
Seeding the CGM: How Satellites Populate the Cold Phase of Milky Way Halos
Manami Roy, Kung-Yi Su, Stephanie Tonnesen +2
The origin of the cold phase in the CGM is a highly debated question. We investigate the contribution of satellite galaxies to the cold gas budget in the circumgalactic medium (CGM…
Dense stellar clump formation driven by strong quasar winds in the FIRE cosmological hydrodynamic simulations
Jonathan Mercedes-Feliz, Daniel Anglés-Alcázar, Boon Kiat Oh +9
We investigate the formation of dense stellar clumps in a suite of high-resolution cosmological zoom-in simulations of a massive, star forming galaxy at under the presen…
Bridging Scales in Black Hole Accretion and Feedback: Magnetized Bondi Accretion in 3D GRMHD
Hyerin Cho, Ben S. Prather, Ramesh Narayan +4
Fueling and feedback couple supermassive black holes (SMBHs) to their host galaxies across many orders of magnitude in spatial and temporal scales, making this problem notoriously…
An Analytic Model For Magnetically-Dominated Accretion Disks
Philip F. Hopkins, Jonathan Squire, Eliot Quataert +6
Recent numerical cosmological radiation-magnetohydrodynamic-thermochemical-star formation simulations have resolved the formation of quasar accretion disks with Eddington or super-…
FORGE'd in FIRE II: The Formation of Magnetically-Dominated Quasar Accretion Disks from Cosmological Initial Conditions
Philip F. Hopkins, Jonathan Squire, Kung-Yi Su +9
In a companion paper, we reported the self-consistent formation of quasar accretion disks with inflow rates down to <300 Schwarzschild radii fro…
Synchrotron Signatures of Cosmic Ray Transport Physics in Galaxies
Sam B. Ponnada, Iryna S. Butsky, Raphael Skalidis +7
Cosmic rays (CRs) may drive outflows and alter the phase structure of the circumgalactic medium, with potentially important implications on galaxy formation. However, these effects…
FORGE'd in FIRE: Resolving the End of Star Formation and Structure of AGN Accretion Disks from Cosmological Initial Conditions
Philip F. Hopkins, Michael Y. Grudic, Kung-Yi Su +8
It has recently become possible to zoom-in from cosmological to sub-pc scales in galaxy simulations to follow accretion onto supermassive black holes (SMBHs). However, at some poin…
Synchrotron Emission on FIRE: Equipartition Estimators of Magnetic Fields in Simulated Galaxies with Spectrally-Resolved Cosmic Rays
Sam B. Ponnada, Georgia V. Panopoulou, Iryna S. Butsky +7
Synchrotron emission is one of few observable tracers of galactic magnetic fields (\textbf{B}) and cosmic rays (CRs). Much of our understanding of \textbf{B} in galaxies comes from…
Accretion onto disk galaxies via hot and rotating CGM inflows
Jonathan Stern, Drummond Fielding, Zachary Hafen +5
Observed accretion rates onto the Milky-Way and other local spirals fall short of that required to sustain star formation for cosmological timescales. A potential avenue for this u…
The impact of AGN-driven winds on physical and observable galaxy sizes
R. K. Cochrane, D. Anglés-Alcázar, J. Mercedes-Feliz +9
Without AGN feedback, simulated massive, star-forming galaxies become too compact relative to observed galaxies at z<2. In this paper, we perform high-resolution re-simulations of…
Arkenstone I: A Novel Method for Robustly Capturing High Specific Energy Outflows In Cosmological Simulations
Matthew C. Smith, Drummond B. Fielding, Greg L. Bryan +11
Arkenstone is a new model for multiphase, stellar feedback driven galactic winds designed for inclusion in coarse resolution cosmological simulations. In this first paper of a seri…
Local positive feedback in the overall negative: the impact of quasar winds on star formation in the FIRE cosmological simulations
Jonathan Mercedes-Feliz, Daniel Anglés-Alcázar, Christopher C. Hayward +10
Negative feedback from accreting supermassive black holes is regarded as a key ingredient in suppressing star formation and quenching massive galaxies. However, several models and…
