The impact of high pressure cluster environment on the X-ray luminosity of Coma early-type galaxies.

FINOGUENOV A. and MINIATI F.

Abstract (from CDS):

We present an observational study of the LX vs. LB σ2 relation for early-type galaxies in the Coma cluster based on the XMM-Newton survey data. Compared to a similar relation for a sample dominated by field early-type galaxies, the Coma cluster galaxies show a flatter slope. Our calculations show that adiabatic compression produces a flattening in the LX vs. LBσ2 relation that is in remarkable agreement with the observed effect. Our scenario is further supported by the observed compactness of the X-ray emission of Coma galaxies.
