The proposed observations will reach Lx 7 x 10^{37} erg/s, yielding over 40 high-mass X-ray binaries (XRBs). Archival UV data and supporting Hubble Space Telescope observations fully leverage our proposed Chandra observations by allowing us to: (a) measure the age and metallicity distribution of young XRBs; (b) measure the formation efficiency of young XRBs as a function of the age of their parent stellar populations; (c) constrain XRB formation models; (d) characterize the ultra-luminous XRB population; (e) explore the role of star formation in energizing the ISM; and (f) identify the nature of the nuclear source.</style></abstract></record></records></xml>
