Abstract:
With this white paper we recommend Milky Way HEPCATs (High Energy Panoramas of Cool Attitude Targets), a comprehensive Chandra/ACIS-I program to survey massive star-forming regions (MSFRs) in the Galactic Plane. HEPCATs will transform Chandra's operational necessity for cool attitude targets into a rich scientific legacy by X-raying the Galaxy's spiral arms. Its primary goal is to obtain ~2500 sharp X-ray snapshots of WISE and Spitzer bubbles, to reveal the massive stars driving these iconic structures and the wind-generated hot plasma that fills them. Over time, HEPCATs will build up wide-field X-ray mosaics of the vast giant molecular clouds that fuel the great MSFR complexes in the Milky Way, blazing a trail for future high-resolution X-ray missions.
