The collective X-ray luminosity of HMXB as a SFR indicator

High Energy Astrophysical Phenomena 2015-05-20 v1

Abstract

We study the relation between the X-ray luminosity of compact sources and the SFR of the host galaxy. Our sample includes 38 galaxies for which a uniform set of X-ray, infra-red and ultraviolet data from Chandra, Spitzer and GALEX has been collected. Our primary goals are (i) to obtain a more accurate calibration of the Lx-SFR relation and (ii) to understand the origin of the dispersion in the Lx-SFR relation observed in previous studies. Preliminary results of this project are reported below.
