A merger shock traced by radio arcs and ultra-long radio tails in galaxy cluster A2142
Chong Ge, Ming Sun, Chris Nolting +2
Abell 2142 (A2142) is a massive, nearby galaxy cluster undergoing a complex merger. It exhibits an elongated X-ray morphology along the northwest-southeast axis and hosts four know…
The shocking features in the closest rich galaxy cluster Norma
Chong Ge, Ming Sun, Mpati Ramatsoku +2
The merger shocks generated by the collision of galaxy clusters elevate the pressure within the intracluster medium, significantly influencing the evolution of embedded cluster gal…
Constraining star formation in M87 using deep HST UV data
Prathamesh Tamhane, William Waldron, Ming Sun +11
We analyzed the deepest Hubble Space Telescope (HST) F275W ultraviolet (UV) imaging of M87 to obtain the most robust constraints on its star formation rate (SFR) and star formation…
XRISM constraints on unidentified X-ray emission lines, including the 3.5 keV line, in the stacked spectrum of ten galaxy clusters
XRISM Collaboration, Marc Audard, Hisamitsu Awaki +150
We stack 3.75 Megaseconds of early XRISM Resolve observations of ten galaxy clusters to search for unidentified spectral lines in the 2.5-15 keV band (rest frame), including t…
The RESOLVE and ECO G3 Initiative: Drivers of HI Content and X-ray Emission in Galaxy Groups
Zackary L. Hutchens, Sheila J. Kannappan, Kelley M. Hess +5
Adding to the RESOLVE and ECO Gas in Galaxy Groups (G3) initiative, we examine possible drivers of group-integrated HI-to-halo mass ratios () and group…
