Spatially Resolved Far-Ultraviolet Spectroscopy of the Nuclear Region of NGC 1068
W. Zheng, J. Wang, G. A. Kriss +5
We carry out high-resolution FUSE spectroscopy of the nuclear region of NGC 1068. The first set of spectra was obtained with a 30" square aperture that collects all emission from t…
The Ionized Gas and Nuclear Environment in NGC 3783 V. Variability and Modeling of the Intrinsic Ultraviolet Absorption
J. R. Gabel, S. B. Kraemer, D. M. Crenshaw +13
We present results on the location, physical conditions, and geometry of the outflow in the Seyfert 1 galaxy NGC 3783 from a study of the variable intrinsic UV absorption. Based on…
Observations and Theoretical Implications of the Large Separation Lensed Quasar SDSS J1004+4112
M. Oguri, N. Inada, C. R. Keeton +25
We study the recently discovered gravitational lens SDSS J1004+4112, the first quasar lensed by a cluster of galaxies. It consists of four images with a maximum separation of 14.62…
Detection of Intergalactic HeII Absorption at Redshift 3.5
W. Zheng, K. Chiu, S. F. Anderson +5
The large number of quasars found in the Sloan Digital Sky Survey has allowed searches for elusive, clear lines of sight towards HeII Ly-alpha absorption, a sensitive probe of the…
Discovery of Two Distant Type Ia Supernovae in the Hubble Deep Field North with the Advanced Camera for Surveys
John P. Blakeslee, Zlatan I. Tsvetanov, Adam G. Riess +30
We present observations of the first two supernovae discovered with the recently installed Advanced Camera for Surveys (ACS) on the Hubble Space Telescope. The supernovae were foun…
