Ultraviolet Line Spectra of Metal-Poor Star-Forming Galaxies
Claus Leitherer, Joao Leao, Tim Heckman +3
We present synthetic ultraviolet spectra of metal-poor star-forming galaxies which were calculated with the Starburst99 package. A new spectral library was generated from HST obser…
High-Redshift Quasars Found in Sloan Digital Sky Survey Commissioning Data V. Hobby-Eberly Telescope Observations
Donald P. Schneider, Xiaohui Fan, Michael A. Strauss +5
We report the discovery of 27 quasars with redshifts between 3.58 and 4.49. The objects were identified as high-redshift candidates based on their colors in Sloan Digital Sky Surve…
The Seyfert-Starburst Connection in X-rays. II. Results and Implications
N. A. Levenson, K. A. Weaver, T. M. Heckman
We present the results of X-ray imaging and spectroscopic analysis of a sample of Seyfert 2 galaxies that contain starbursts, based on their optical and UV characteristics. These c…
The Seyfert-Starburst Connection in X-rays. I. The Data
N. A. Levenson, K. A. Weaver, T. M. Heckman
We analyze X-ray spectra and images of a sample of Seyfert 2 galaxies that unambiguously contain starbursts, based on their optical and UV characteristics. Although all sample memb…
NICMOS Imaging of the Host Galaxies of z ~ 2 - 3 Radio-Quiet Quasars
S. E. Ridgway, T. M. Heckman, D. Calzetti +1
We have made a deep NICMOS imaging study of a sample of 5 z ~ 2 - 3 radio-quiet quasars with low absolute nuclear luminosities, and we have detected apparent host galaxies in all o…
Hiden Star Formation: The Ultraviolet Perspective
G. R. Meurer, T. M. Heckman, M. Seibert +4
Many recent estimates of the star formation rate density at high redshift rely on rest-frame ultraviolet (UV) data. These are highly sensitive to dust absorption. Applying a correl…
