On the X-ray emission of the low-mass galaxy groups.
TOVMASSIAN H.M., YAM O. and TIERSCH H.
Abstract (from CDS):
It is shown that low-mass groups obey the LX~σ4v law deduced for galaxy clusters. The impression of the more shallow slope of the LX-σv correlation for groups is created not by enhanced X-ray emission, but by the underestimation of the radial velocity dispersion of some groups.
