A New Observational Upper Limit to the Low Redshift Ionizing Background Radiation
R. J. Weymann, S. N. Vogel, S. Veilleux +1
We report a new Fabry-Perot search for Halpha emission from the intergalactic cloud HI 1225+01 in an attempt to measure the low redshift ionizing background radiation. We set a new…
The Farthest Known Supernova: Support for an Accelerating Universe and a Glimpse of the Epoch of Deceleration
Adam G. Riess, Peter E. Nugent, Brian P. Schmidt +16
We present photometric observations of an apparent Type Ia supernova (SN Ia) at a redshift of ~1.7, the farthest SN observed to date. SN 1997ff, was discovered in a repeat observat…
The QSO - Ultraluminous Infrared Galaxies Connection
S. Veilleux, D. -C. Kim, D. B. Sanders
For the past several years, our group has pursued a vigorous ground-based program aimed at understanding the nature of ultraluminous infrared galaxies. We recently published the re…
New Results from a Survey of Galactic Outflows in Nearby Active Galactic Nuclei
S. Veilleux, G. Cecil, J. Bland-Hawthorn +1
Recent results from a multiwavelength survey of spatially resolved outflows in nearby active galaxies are presented. Optical Fabry-Perot and long-slit spectroscopic data are combin…
Jet- and Wind-Driven Ionized Outflows in the Superbubble and Star-Forming Disk of NGC 3079
G. Cecil, J. Bland-Hawthorn, S. Veilleux +1
HST WFPC2 images are presented that span the inner 19 kpc diameter of the edge-on spiral galaxy NGC 3079; they are combined with ground-based Halpha+[N II] Fabry-Perot spectra and…
