Description
We have been regularly observing the bulge and inner disk of M31 for nearly one year, using both the HRC-I and ACIS-I instruments on the Chandra X-Ray Observatory. We present results from our program that are of interest to the study of the ISM in M31. In particular, we find that the unresolved emission within 3' of the center of M31 has a distinctly softer spectrum than that of most of the resolved X-ray sources in the region. Preliminary spectral analysis of bright point sources in the bulge shows no evidence (within the poor statistics) for soft spectral components, but does reveal significant extra-galactic X-ray extinction (NH ~ 1021 cm-2). We find no new X-ray counterparts to supernova remnants to date.

    Galaxy archaeology - The quest for ancient mergers
    The hierarchical assembly of galaxies through mergers is a key channel of galaxy evolution in the ΛCDM cosmological model. Quantifying these ancient transformative accretion events from observations of present day galaxies is a crucial goal of extragalactic archeology. Achieving this goal is challenging as the dominant epoch of galaxy assembly lies

    RAD@home Citizen Scientists Uncover Emerging Jet-Galaxy Interactions
    The RAD12 object's recent investigation (Hota et al. 2022), via the RAD@home Astronomy Collaboratory, has provided a streamlined and focused perspective on the complex subject of jet-galaxy interactions, which has always posed a significant challenge for observational confirmation. This emerging field holds increasing significance, providing a

    A Disc Wind Where You Least Expect It: The Outflow in the Short-period X-ray Binary UW CrB
    Studying outflows of low mass X-ray binaries (LMXBs) is important for understanding the physics of accretion, the evolution of compact binaries, and dynamics of the local interstellar medium. One significant source of these outflows is the accretion disc wind, which can blow away vast amounts of material from the disc before it can be accreted on
