Navigating low-metallicity galaxies: clearing X-ray binary channels and mapping feedback currents in NGC3109.
Abstract
We propose a joint, 100 ks Chandra and 30 ks XMM-Newton study of the low-metallicity galaxy NGC3109. By combining unprecedented spatial resolution of Chandra with the soft XMM-Newton response, we will obtain a census of X-ray binaries, probe the nature of accreting sources, and find hot bubbles in this template low-metallicity galaxy. New Chandra observations will complement the HST observations of massive stars in NGC3109. Obtaining first robust measurements of X-ray sources in NGC3109 is a necessary next step to progress in our understanding of massive binary star evolution and feedback at low-metallicities and, by proxy, in early cosmic times.
