Low-Mass X-Ray Binaries and Globular Clusters in Centaurus A**Based on observations with the NASA/ESA Hubble Space Telescope obtained at STScI,which is operated by AURA, Inc., under NASA contract NAS 5-26555.
Abstract
We present results of Hubble Space Telescope and Chandra X-Ray Observatory observations of globular clusters (GCs) and low-mass X-ray binaries (LMXBs) in the central regions of Centaurus A. Out of 440 GC candidates, we find 41 host X-ray point sources that are most likely LMXBs. We fit King models to our GC candidates in order to measure their structural parameters. We find that GCs that host LMXBs are denser and more compact and have higher …
