cds-question@unistra.frx-ray-sourcesh-ii-regionsWe present the Massive Star-forming Regions (MSFRs) Omnibus X-ray Catalog (MOXC), a compendium of X-ray point sources from Chandra/ACIS observations of a selection of MSFRs across the Galaxy, plus 30 Doradus in the Large Magellanic Cloud. MOXC consists of 20623 X-ray point sources from 12 MSFRs with distances ranging from 1.7kpc to 50kpc. Additionally, we show the morphology of the unresolved X-ray emission that remains after the cataloged X-ray point sources are excised from the ACIS data, in the context of Spitzer and WISE observations that trace the bubbles, ionization fronts, and photon-dominated regions that characterize MSFRs. In previous work, we have found that this unresolved X-ray emission is dominated by hot plasma from massive star wind shocks. This diffuse X-ray emission is found in every MOXC MSFR, clearly demonstrating that massive star feedback (and the several-million-degree plasmas that it generates) is an integral component of MSFR physics.2014ApJS..213....1Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/213/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-2014)B/ocl : Optically visible open clusters and Candidates (Dias+ 2002-2013)J/ApJS/209/32 : Probable young stars in the MYStIX project (Broos+, 2013)J/ApJS/209/31 : The MYStIX IR-Excess Source catalog (MIRES) (Povich+, 2013)J/ApJS/209/30 : MYStIX project: Bayesian matching (Naylor+, 2013)J/ApJS/209/29 : MYStIX: Mid-IR observations and catalogs (Kuhn+, 2013)J/ApJS/209/28 : MYStIX Wide-Field NIR data: crowded fields (King+, 2013)J/ApJS/209/27 : MYStIX: the Chandra X-ray sources (Kuhn+, 2013)J/A+A/552/A123 : Far-IR study of G29.96-0.02 (Beltran+, 2013)J/A+A/538/A142 : OB stars in NGC 6334 and NGC 6357 (Russeil+, 2012)J/ApJ/753/117 : X-ray catalog of Eagle Nebula (Guarcello+, 2012)J/ApJ/743/39 : Spitzer obs. of W3 molecular cloud (Rivera-Ingraham+, 2011)J/ApJ/733/113 : IRAC observations of IC 1795 (Roccatagliata+, 2011)J/A+A/526/A151 : Hi-Gal sources distance determination (Russeil+, 2011)J/ApJS/194/15 : CCCP: Carina's diffuse X-ray emission (Townsley+, 2011)J/ApJS/194/9 : X-ray star clusters in the Carina complex (Feigelson+, 2011)J/ApJS/194/4 : Classification of CCCP X-ray sources (Broos+, 2011)J/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)J/ApJ/725/2485 : X-rays from the star-forming complex W40 (Kuhn+, 2010)J/ApJ/708/1760 : Flux estimations of faint X-ray sources (Getman+, 2010)J/A+A/521/A61 : Stars associated to Eagle Nebula (M16) (Guarcello+ 2010)J/A+A/515/A55 : NGC 6334-NGC 6357 complex (Russeil+, 2010)J/AJ/138/227 : Stellar clusters in NGC 6334 complex (Feigelson+, 2009)J/ApJ/696/1278 : The extended star-forming environment of M17 (Povich+, 2009)J/ApJ/675/1319 : Infrared photometry of NGC 3603 (Harayama+, 2008)J/AJ/136/2083 : NGC 6334 clumps from 450/850um observations (Matthews+, 2008)J/ApJ/668/906 : Massive clumps in NGC 6334 (Munoz+, 2007)J/ApJ/654/347 : Chandra X-ray obs. in Eagle Nebula.
