We present the second installment of the Massive Star-forming Regions (MSFRs)Omnibus X-ray Catalog (MOXC2), a compilation of X-ray point sources detected inChandra/ACIS observations of 16 Galactic MSFRs and surrounding fields. MOXC2includes 13 ACIS mosaics, three containing a pair of unrelated MSFRs atdifferent distances, with a total catalog of 18,396 point sources. The MSFRssampled range over distances of 1.3 kpc to 6 kpc and populations varying fromsingle massive protostars to the most massive Young Massive Cluster known inthe Galaxy. By carefully detecting and removing X-ray point sources down to thefaintest statistically-significant limit, we facilitate the study of theremaining unresolved X-ray emission. Through comparison with mid-infraredimages that trace photon-dominated regions and ionization fronts, we see thatthe unresolved X-ray emission is due primarily to hot plasmas threading theseMSFRs, the result of feedback from the winds and supernovae of massive stars.The 16 MSFRs studied in MOXC2 more than double the MOXC1 sample, broadening theparameter space of ACIS MSFR explorations and expanding Chandra's substantialcontribution to contemporary star formation science.
