Comment: van Weeren et al 2011
Estimate of 200 redshifts comes from 3 Deimos masks (one observed in
January 2013 yielded only 19 confirmed members; 2 were observed in Dec
2013) and 26 in NED.
Aguerri
et al. (2007) reported a velocity dispersion of
665+51-45 km/s and an r200 radius of 1.52 Mpc
based on SDSS data.
Fig 21 from van
Weeren et al 2011. Left: RXC J1053.7+5452 WSRT 1382 MHz
image. Contour levels are drawn as in Fig. 1. Black dotted lines
indicate the integration area for the flux measurement. Right: RXC
J1053.7+5452 X-ray emission from ROSAT in orange. The original image
from the ROSAT All Sky Survey was convolved with a 225" FWHM
Gaussian. Solid contours are from the WSRT 1382 MHz image and drawn at
levels of [1,2,4,8,...] x 4sigma rms. Dashed contours show the galaxy
iso-density distribution derived from the SDSS survey. Contours are
drawn at [1.0,1.2,1.4,...] x 0.25 galaxies arcmin-2 selecting only
galaxies with 0.05 < zphot < 0.1. Discrete sources embedded in the
diffuse emission are alphabetically labeled, see Table 3.
