作为SFR指示剂的HMXB的集体X射线光度

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

Stefano Mineo, Marat Gilfanov, Rashid Sunyaev

摘要:

研究了致密源的X射线光度与宿主星系的SFR之间的关系。我们的样本包括38个星系,其中一组统一的X射线,红外和紫外线数据从钱德拉,斯皮策和GALEX已收集。我们的主要目标是(i)获得更准确的校准Lx-SFR关系和(ii)了解在以前的研究中观察到的Lx-SFR关系的分散的起源。该项目的初步成果报告如下。

英文摘要:

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.
