Walker,_Stephen_mediumI am a NASA Postdoctoral Program Fellow at NASA’s Goddard Space Flight Center. My research concentrates on all aspects of galaxy clusters (the largest collapsed structures in the universe), from the outskirts where they are continuing to form, to gas sloshing produced by galaxy cluster mergers, to studying AGN feedback in cluster cores, focusing on their X-ray emission.
