Descripción
We examine seven Chandra ACIS-I observations centered on the nucleus of
M31. Recent Chandra [1] and XMM results [2] have shown evidence of
diffuse emission and have shown this emission to be softer than the
point sources present in the nucleus. We also see a gradient in the
hardness ratio with respect to radius in the diffuse emission. We will
report on spectral fits to the diffuse emission (after point sources
have been removed) in order to constrain the emission mechanism. We will
also compare this to a few representative point sources in the nuclear
region. These fits should provide some insight into the origin of this
diffuse emission.
