SPT-CL J0417-4748: A Deep Chandra Study of a Relaxed Galaxy Cluster Without Central Star Formation
Taweewat Somboonpanyakul, Adam B. Mantz, Steven W. Allen +7
We present an in-depth Chandra X-ray analysis of the galaxy cluster SPT-CL J04174748 (hereafter SPT J0417), at z = 0.58, with a focus on its thermodynamic properties and the app…
Multiwavelength Characterization of a Dynamically Relaxed Cool Core Galaxy Cluster at
Anthony M. Flores, Adam B. Mantz, Steven W. Allen +5
We present imaging and spectroscopic analyses of Chandra and XMM-Newton observations of ACT-CL J0123.50428, one of the most massive, highest redshift galaxy clusters detected wi…
Deep Chandra Observations of the z = 1.16 Relaxed, Cool-core Galaxy Cluster SPT-CL J2215-3537
Haley R. Stueber, Adam B. Mantz, Steven W. Allen +10
Galaxy clusters serve as a unique and valuable laboratory for probing cosmological models and understanding astrophysics at the high-mass limit of structure formation. Clusters tha…
Cold Gas and Star Formation in the Phoenix Cluster with JWST
Michael Reefe, Michael McDonald, Marios Chatzikos +16
We present integral field unit observations of the Phoenix Cluster with the JWST Mid-infrared Instrument's Medium Resolution Spectrometer (MIRI/MRS). We focus this study on the mol…
The QPO in REJ1034+396 originates in the hot corona
Chloe Taylor, Daniel Wilkins, Steven Allen
REJ1034+396 is one of the few active galactic nuclei with a significant quasi-periodic oscillation (QPO). The QPO has been observed in over 1 Ms of XMM-Newton observations spanning…
Directly Imaging the Cooling Flow in the Phoenix Cluster
Michael Reefe, Michael McDonald, Marios Chatzikos +14
In the centers of many galaxy clusters, the hot (10 K) intracluster medium (ICM) can become dense enough that it should cool on short timescales. However, the low measure…
