Line Emission Mapper (LEM): Probing the physics of cosmic ecosystems
Ralph Kraft, Maxim Markevitch, Caroline Kilbourne +107
The Line Emission Mapper (LEM) is an X-ray Probe for the 2030s that will answer the outstanding questions of the Universe's structure formation. It will also provide transformative…
Gas sloshing and cold fronts in pre-merging galaxy cluster Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +10
We present deep Chandra observations of the pre-merger galaxy cluster Abell 98. Abell 98 is a complex merging system. While the northern (A98N) and central subclusters (A98S) are m…
Chemical abundances in the outskirts of nearby galaxy groups measured with joint Suzaku and Chandra observations
Arnab Sarkar, Yuanyuan Su, Nhut Truong +5
We report results from deep Suzaku and mostly snapshot Chandra observations of four nearby galaxy groups: MKW4, Antlia, RXJ1159+5531, and ESO3060170. Their peak temperatures vary o…
Discovery of a pre-merger shock in an intercluster filament in Abell 98
Arnab Sarkar, Scott Randall, Yuanyuan Su +11
We report the first unambiguous detection of an axial merger shock in the early-stage merging cluster Abell 98 using deep (227 ks) Chandra observations. The shock is about 420 kpc…
Resilience of Sloshing Cold Fronts against Subsequent Minor Mergers
Iraj Vaezzadeh, Elke Roediger, Claire Cashmore +8
Minor mergers are common in galaxy clusters. They have the potential to create sloshing cold fronts (SCFs) in the intracluster medium (ICM) of the cluster. However, the resilience…
The Merger Dynamics of the X-ray Emitting Plasma in Clusters of Galaxies
John ZuHone, Yuanyuan Su
As the formation of cosmic structure continues to proceed, we observe one of the latest stages of this process in mergers of clusters of galaxies with other clusters, groups, and g…
