Chandra image A2146

Merger between two galaxy clusters Abell 2146.  Hubble image (White et al. 2015) showing galaxies (in white) is superposed on an X-ray image (purple/blue) taken with the Chandra X-ray Observatory by Helen Russell, a former Waterloo postdoctoral fellow and currently a professor at University of Nottingham in the UK.  The image reveals a bow shock as bright galaxies and their dark matter halos plow into the cluster at high speed.  The image is featured for the Chandra Observatory’s 20th anniversary celebration.  WCA’s Prof. Brian McNamara will present an invited talk at “20 Years of Chandra Science Symposium” Dec. 3-6, at Boston, Mass. USA.
