Macroscopic magnetization of primordial plasma by virial shocks
Uri Keshet, Kuan-Chou Hou
Galaxy-cluster virial (structure-formation accretion) shock observations are shown to imply magnetization of a layer extending Debye lengths downstrea…

Galaxy cluster virial-shock sources in eROSITA catalogs
Gideon Ilani, Kuan-Chou Hou, Gil Nadler +1
Following the recent identification of discrete ROSAT and radio sources associated with the virial shocks of MCXC clusters and groups, we examine if the early eROSITA-DE data relea…

Excess cataloged X-ray and radio sources at galaxy-cluster virial shocks
Gideon Ilani, Kuan-Chou Hou, Uri Keshet
We detect a highly significant excess of X-ray (2RXS) and radio (NVSS, GMRT, VLSSr) catalog sources when stacked around MCXC galaxy clusters and groups, narrowly confined within $\…
