General Fields of Investigation:
Normal galaxies and their different X-ray emission components; XRB populations; the hot ISM and mass measurements of early-type galaxies; the connection between galaxy environment and nuclear activity. Optical, IR, UV, and radio observations are obtained to supplement the X-ray data.
Galaxies are key objects for the study of cosmology, the life cycle of matter, and stellar evolution. X-ray observations have given us a new key band for understanding these building blocks of the Universe, with implications ranging from the study of extreme physical situations, such as can be found in the proximity of Black Holes, or near the surface of neutron stars; to the interaction of galaxies and their environment; to the measure of parameters of fundamental cosmological importance.
