Scientific paper

W75N/DR21 is a complex of several massive star-forming regions at a distance of 2-3 kpc in Cygnus. Recent wide-field imaging survey program using Spitzer/IRAC, UKIRT/WFCAM, and JCMT/SCUBA revealed the entire picture of this complex, which is filled with various signatures of massive star birth. The central part of the complex, DR21, is scheduled to be observed by a deep ACIS-I pointing in the cycle 8. By adding two more ACIS-I pointings, we will cover all the major regions in this complex. The primary objective is to conduct a census of weak-line T Tauri stars using their elevated X-ray emission. By combining with the longer wavelength datasets that are sensitive to less evolved population, we will understand how the star formation proceeded in this region.
