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…
Second public data release of the FIRE-2 cosmological zoom-in simulations of galaxy formation
Andrew Wetzel, Jenna Samuel, Pratik J. Gandhi +34
We describe the second data release (DR2) of the FIRE-2 cosmological zoom-in simulations of galaxy formation, from the Feedback In Realistic Environments (FIRE) project, available…
X-ray emission signatures of galactic feedback in the hot circumgalactic medium: predictions from cosmological hydrodynamical simulations
Emily M. Silich, John ZuHone, Elena Bellomi +6
Little is currently known about the physical properties of the hot circumgalactic medium (CGM) surrounding massive galaxies. Next-generation X-ray observatories will enable detaile…
A Practical Guide to Hosting a Virtual Conference
Cameron Hummels, Benjamin Oppenheimer, G. Mark Voit +1
Virtual meetings have long been the outcast of scientific interaction. For many of us, the COVID-19 pandemic has only strengthened that sentiment as countless Zoom meetings have le…
Introducing the Descriptive Parametric Model: Gaseous Profiles for Galaxies, Groups, and Clusters
Benjamin D. Oppenheimer, G. Mark Voit, Yannick M. Bahé +14
We develop and present the Descriptive Parametric Model (DPM), a tool for generating profiles of gaseous halos (pressure, electron density, and metallicity) as functions of radius,…
Constraining cosmic ray transport models using circumgalactic medium properties and observables
Yue Samuel Lu, Dušan Kereš, Philip F. Hopkins +3
Cosmic rays (CRs) are a pivotal non-thermal component of galaxy formation and evolution. However, the intricacies of CR physics, particularly how they propagate in the circumgalact…
Turbulence-dominated CGM: the origin of UV absorbers with equivalent widths of Å
Aharon Kakoly, Jonathan Stern, Claude-André Faucher-Giguère +4
Theoretical arguments and observations suggest that in massive halos (), the circumgalactic medium (CGM) is dominated by a 'hot' phase with gas temperature near…
