At a distance of about 2 kpc is lies a remarkable 300 pc above the galactic plane. It is generally divided into 2 subregions, east and west, based on the $^{12}$CO distribution (Elmegreen \& Lada 1978). In the western part of NGC 281, is a large bubble H\II~ region prominent features include a young open cluster of stars (IC 1590), and a large lane of obscuring gas and dust. To the east, along the ionization front is a smaller, less stressed, embedded cluster. The cloud seems to be under active stress from the H\II~ region. The Pac Man Nebula, NGC 281, was observed with Chandra for 100 ksec using the Advanced CCD Imaging Spectrometer (ACIS) supported by data from the Spitzer IRAC and MIPS instruments. NGC 281 was observed with Chandra in 2005 for almost 100 ks with the ACIS in three sets of observations. This work involves identification of point sources in NGC 281, photometry and spectroscopy of brighter sources to separate them from the diffuse emission. We find the Xray luminosity function and study its completeness and estimate the number of missing sources and their energy and energy distribution. We also use Spitzer data to study the Young Stellar Population and the spatial distribution of Class I, Class II and Class III sources. |
