Effects of Varied Cosmic Ray Feedback from AGN on Massive Galaxy Properties

Charvi Goyal, Sam B. Ponnada, Philip F. Hopkins +3

Active galactic nuclei (AGN) provide energetic feedback necessary to `turn off' star formation in high-mass galaxies (M 10 M, $10.4 \leq \log(…

Little Red Dots on FIRE: The Ability of Bursty Galaxies to Host an Abundant Population of High-Redshift AGN

Andrew Marszewski, Claude-André Faucher-Giguère, Guochao Sun +5

The James Webb Space Telescope has unveiled an abundant population of potential active galactic nuclei (AGN) at high redshift () known as little red dots (LRDs), which a…

Bridging Scales in Black Hole Accretion and Feedback: Subgrid Prescription from First Principles

Hyerin Cho, Ben S. Prather, Ramesh Narayan +4

Understanding how supermassive black holes (BHs) couple to their host galaxies across a vast spatial and temporal dynamic range remains a central challenge in galaxy evolution. Usi…

Bridging scales: Modeling suppressed Bondi accretion on black holes and its impact on galaxy growth

Antonio J. Porras-Valverde, Priyamvada Natarajan, Angelo Ricarte +4

The accretion and feedback processes governing supermassive black hole (SMBH) growth span an enormous range of spatial scales, from the Event Horizon to the circumgalactic medium.…

Bridging scales: How much do supermassive black holes grow in the suppressed Bondi regime?

Kung-Yi Su, Angelo Ricarte, Priyamvada Natarajan +6

The co-evolution of supermassive black holes (SMBHs) and their host galaxies remains one of the central open questions in cosmology, rooted in the coupling between accretion, feedb…

To Survive or to Shatter: The Impact of Cosmic Rays on the Fate of Stripped Cold Clouds

Manami Roy, Kung-Yi Su, Stephanie Tonnesen +3

Does cosmic ray (CR) pressure matter for the circumgalactic medium (CGM)? Despite growing interest, this remains a debated question, complicated by limited observational constraint…
