Spectroscopic galaxy redshifts in the Peanut cluster -- a massive nearly head-on cluster merger shortly after pericenter passage
I. Zaznobin, N. Lyskova, I. Bikmaev +13
The Peanut cluster (SRGe J023820.8+200556, SRGe CL0238.3+2005, = 0.42) has recently emerged as a candidate for a rare, massive merger, potentially analogous to the Bulle…

X-ray flux -- mass relation for galaxy clusters
Natalia Lyskova, Eugene Churazov, Ildar Khabibullin +3
We use a subsample of co-detections of the ACT and MaDCoWS cluster catalogs to verify the predicted relation between the observed X-ray flux in the 0.5-2~keV band and the clu…
