Research Activities of Gerard A. Kriss

Gerard Kriss serves as the head of the Instruments Division (INS) Space Telescope Science Institute

Dr. Kriss's current research concentrates on observations of quasars and active galaxies, at all wavelengths from the X-ray through the radio. Using far-ultraviolet spectra from the Hopkins Ultraviolet Telescope (HUT) and the Far Ultraviolet Spectroscopic Explorer (FUSE) and HST images and spectra of quasars and Seyfert galaxies, he is searching for evidence of accretion disks around supermassive black holes and clues to the internal structure of active galaxies. Using bright, distant quasars as background light sources, he is also studying the ionization and composition of the intergalactic medium using the absorption lines it imprints on the quasar spectra. A list of his publications is available.
