A z=0.9 supercluster of X-ray luminous, optically-selected, massive galaxy clusters
David G. Gilbank, H. K. C. Yee, E. Ellingson +4
We report the discovery of a compact supercluster structure at z=0.9. The structure comprises three optically-selected clusters, all of which are detected in X-rays and spectroscop…
Discovery of a Metal-Line Absorber Associated with a Local Dwarf Starburst Galaxy
Brian A. Keeney, John T. Stocke, Jessica L. Rosenberg +2
We present optical and near-infrared images, H I 21 cm emission maps, optical spectroscopy, and Hubble Space Telescope/Space Telescope Imaging Spectrograph ultraviolet spectroscopy…
Does the Milky Way Produce a Nuclear Galactic Wind?
Brian A. Keeney, Charles W. Danforth, John T. Stocke +3
We detect high-velocity absorbing gas using Hubble Space Telescope and Far Ultraviolet Spectroscopic Explorer medium resolution spectroscopy along two high-latitude AGN sight lines…
Absorption Line Study of Halo Gas in NGC 3067 Toward the Background Quasar 3C 232
Brian A. Keeney, Emmanuel Momjian, John T. Stocke +2
We present new H I 21 cm absorption data and ultraviolet spectroscopy from HST/STIS of the QSO/galaxy pair 3C 232/NGC 3067. The QSO sightline lies near the minor axis and 1.8 arcmi…
Absolute Proper Motion of the Fornax Dwarf Spheroidal Galaxy from Photographic and HST WFPC2 Data
Dana I. Dinescu, Brian A. Keeney, Steve R. Majewski +1
We have measured the absolute proper motion of the Fornax dwarf spheroidal galaxy from a combination of photographic plate material and HST WFPC2 data that provide a time baseline…
Discovery of a Dwarf Post-Starburst Galaxy Near a High Column Density Ly-alpha Absorber
J. T. Stocke, B. A. Keeney, K. M. McLin +3
We report the discovery of a dwarf (M_B = -13.9) post-starburst galaxy coincident in recession velocity (within uncertainties) with the highest column density absorber (N_HI = 10^1…
