HST view of NGC 5044: Constraints on Filament Widths, Magnetic Support, Multiphase Structure, and Comparison with Cluster Environments
Prathamesh Tamhane, Ming Sun, William Waldron +12
We present new Hubble Space Telescope (HST) imaging of ionised filaments in the brightest group galaxy NGC 5044. These filaments extend several kiloparsecs and have widths of $\sim…
Supermassive Black Hole Feedback
Mateusz Ruszkowski, Daisuke Nagai, Irina Zhuravleva +23
Understanding the processes that drive galaxy formation and shape the observed properties of galaxies is one of the most interesting and challenging frontier problems of modern ast…
The Clusters Hiding in Plain Sight (CHiPS) survey: CHIPS1911+4455, a Rapidly-Cooling Core in a Merging Cluster
Taweewat Somboonpanyakul, Michael McDonald, Matthew Bayliss +6
We present high-resolution optical images from the Hubble Space Telescope, X-ray images from the Chandra X-ray Observatory, and optical spectra from the Nordic Optical Telescope fo…
Growth and Evolution of Thermal Instabilities in Idealized Galaxy-Cluster Cores
Gregory Meece, Brian O'Shea, Mark Voit
Heat input roughly balances radiative cooling in the gaseous cores of galaxy clusters even when the central cooling time is short, implying that cooling triggers a feedback loop th…
The XMAGNET exascale MHD simulations of SMBH feedback in galaxy groups and clusters: Overview and preliminary cluster results
Philipp Grete, Brian W. O'Shea, Forrest W. Glines +5
We present initial results from extremely well-resolved 3D magnetohydrodynamical simulations of idealized galaxy clusters, conducted using the AthenaPK code on the Frontier exascal…
XMAGNET : Kinetic, Thermal and Magnetic AGN Feedback in Massive Galaxies at Halo Masses M
Deovrat Prasad, Philipp Grete, Brian O'Shea +5
The interplay between radiative cooling of the circumgalactic medium (CGM) and feedback heating governs the evolution of the universe's most massive galaxies. This paper presents s…
The strongest cool core in REXCESS: Missing X-ray cavities in RXC J2014.8-2430
Tony Mroczkowski, Megan Donahue, Joshiwa van Marrewijk +8
We present a multiwavelength study of RXC J2014.8-2430, the most extreme cool-core cluster in the Representative Cluster Structure Survey (REXCESS), using X-…
