Galaxy cluster virial-shock sources in eROSITA catalogs

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 release (EDR) shows virial-shock X-ray sources within its \(140\) deg\(^2\) field. EDR catalog sources are stacked and radial...

Description
Summary: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 release (EDR) shows virial-shock X-ray sources within its \(140\) deg\(^2\) field. EDR catalog sources are stacked and radially binned around EDR catalog clusters and groups. The properties of the excess virial-shock sources are inferred statistically by comparing the virial-shock region to the field. An excess of X-ray sources is found narrowly localized at the \(2.0
