Distinguishing local and global influences on galaxy morphology: A Hubble Space Telescope comparison of high and low X-ray luminosity clusters

Abstract:

We present a morphological analysis of 17 X-ray-selected clusters at z ∼ 0.25, imaged uniformly with the Hubble Space Telescope Wide Field Planetary Camera 2 (WFPC2). Eight of these clusters comprise a subsample selected for their low X-ray luminosities (≲1044 ergs s -1), called the low-Lx sample. The remaining nine clusters comprise a high-Lx subsample with Lx > 10 45 ergs s-1. The two subsamples differ in their mean X-ray luminosity by a factor of 30 and span a range of more than 300. Th...
