Description
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.

    ROSALIA: ROman Sky Analyst for Low surface brightness Imaging & Astronomy
    Diffuse emission in the outskirts of galaxies, such as stellar tidal streams, galaxy stellar halos and intracluster light, provides important constraints on the structure and evolution of the Universe. However, such low surface brightness diffuse emission can be up to thousands of times dimmer (>29 AB mag/[square arcseconds]) than the sky

    A Systematic Search for and Characterization of White Dwarf Binaries Across the H-R Diagram
    White dwarfs (WDs) are the endpoint of evolution for 97% of stars. Most of these stars are in multiple systems, and a significant fraction of those are compact enough to exchange mass, altering the structures and subsequent evolution of both stars. The physical mechanisms that facilitate these mass exchanges include common envelope evolution, Roche

    The molecular gas perspective on the growth and death of H emitters in the Spiderweb protocluster at Alpha z=2.16
    Galaxy clusters at low redshift are dominated by massive quiescent galaxies hosting stellar populations 10 Gyrs old, indicating that they were formed in the early universe when clusters were still in the process of being assembled (i.e., protoclusters). The rapid growth of galaxies within protoclusters is driven by the efficient transformation of
