The Resolved Sunyaev--Zeldovich Profiles of Nearby Galaxy Groups


الملخص بالإنكليزية

Much of the baryons in galaxy groups are thought to have been driven out to large distances ($gtrsim$$R_{500}$) by feedback, but there are few constraining observations of this extended gas. This work presents the resolved Sunyaev--Zeldovich (SZ) profiles for a stacked sample of 10 nearby galaxy groups within the mass range log$_{10}(M_{500}[M_{odot}]) = 13.6 -13.9$. We measured the SZ profiles using the publicly available $y$-map from the Planck Collaboration as well as our own $y$-maps constructed from more rece
