Scientific paper

We propose to observe the elliptical galaxy NGC3379 with ACIS-S to determine the density distribution and temperature of the hot gas within this early-type galaxy. Based on the observed surface brightness profile and gas temperature, we can determine the kinematic state of the interstellar medium (i.e., a cooling flow, partial wind, or strong wind), the abundance of heavy elements, and the total gravitating mass of the galaxy. Combining this observation with archival data, we can determine the correlation between X-ray and blue luminosity for a sample of early type galaxies spanning a wide range of luminosities.
