Spectroscopy of High-Redshift Supernovae from the ESSENCE Project: The First Four Years
R. J. Foley, T. Matheson, S. Blondin +23
We present the results of spectroscopic observations from the ESSENCE high-redshift supernova (SN) survey during its first four years of operation. This sample includes spectra of…
A Golden Standard Type Ia Supernova SN 2005cf: Observations from the Ultraviolet to the Near-Infrared Wavebands
Xiaofeng Wang, Weidong Li, Alexei V. Filippenko +31
We present extensive photometry at ultraviolet (UV), optical, and near-infrared (NIR) wavelengths, as well as dense sampling of optical spectra, for the normal type Ia supernova (S…
The Chemical Abundances of Tycho G in Supernova Remnant 1572
Jonay I. González Hernández, Pilar Ruiz-Lapuente, Alexei V. Filippenko +3
We present an analysis of the chemical abundances of the star Tycho G in the direction of the remnant of supernova (SN) 1572, based on Keck high-resolution optical spectra. The ste…
Coronal lines and dust formation in SN 2005ip: Not the brightest, but the hottest Type IIn supernova
Nathan Smith, Jeffrey M. Silverman, Ryan Chornock +7
We present optical photometry and spectroscopy of SN2005ip for the first 3yr after discovery, showing an underlying Type II-L SN interacting with a steady wind to yield an unusual…
GALEX Spectroscopy of SN 2005ay suggests a UV spectral uniformity among type II-P supernovae
A. Gal-Yam, F. Bufano, T. Barlow +24
We present the first results from our GALEX program designed to obtain ultraviolet (UV) spectroscopy of nearby core-collapse supernovae (SNe). Our first target, SN 2005ay in the ne…
Luminosity Indicators in the Ultraviolet Spectra of Type Ia Supernovae
Ryan J. Foley, Alexei V. Filippenko, Saurabh W. Jha
We present a complete sample of International Ultraviolet Explorer and Hubble Space Telescope ultraviolet (UV) spectra of Type Ia supernovae (SNe Ia) through 2004. We measure the e…
