CfA3: 185 TYPE Ia SUPERNOVA LIGHT CURVES FROM THE CfA
- M. HickenP. Challis P. Zhao
- 30 January 2009
Physics
We present multiband photometry of 185 type-Ia supernovae (SNe Ia), with over 11,500 observations. These were acquired between 2001 and 2008 at the F. L. Whipple Observatory of the…
A Study of the Type II-Plateau Supernova 1999gi and the Distance to its Host Galaxy, NGC 3184
- D. LeonardA. Filippenko A. Mahdavi
- 29 July 2002
Physics
We present optical spectra and photometry sampling the first 6 months after discovery of supernova (SN) 1999gi in NGC 3184. SN 1999gi is shown to be a Type II-plateau event with a photometric plateau…
UBVRI Light Curves of 44 Type Ia Supernovae
- S. JhaR. Kirshner K. Stanek
- 8 September 2005
Physics
We present UBVRI photometry of 44 Type Ia supernovae (SNe Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
TYPE Ia SUPERNOVA RATE MEASUREMENTS TO REDSHIFT 2.5 FROM CANDELS: SEARCHING FOR PROMPT EXPLOSIONS IN THE EARLY UNIVERSE
- S. RodneyA. Riess D. Kocevski
- 30 January 2014
Physics
The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) was a multi-cycle treasury program on the Hubble Space Telescope (HST) that surveyed a total area of ∼0.25 deg2 with ∼900…
The Progenitor of Supernova 1993J Revisited
- S. V. van DykP. Garnavich P. Challis
- 20 August 2002
Physics
From Hubble Space Telescope images with 0 .″05 resolution, we identify four stars brighter than V = 25 mag within 2 .″5 of SN 1993J in M81, which contaminated previous ground‐based brightness…
THE MOST SLOWLY DECLINING TYPE Ia SUPERNOVA 2001ay
- K. KrisciunasWeidong Li Lifan Wang
- 20 June 2011
Physics
We present optical and near-infrared photometry, as well as ground-based optical spectra and Hubble Space Telescope ultraviolet spectra, of the Type Ia supernova (SN) 2001ay. At maximum light the Si…
GRB 021211 as a Faint Analog of GRB 990123: Exploring the Similarities and Differences in the Optical Afterglows
- S. HollandD. Bersier K. Stanek
- 4 May 2004
Physics
We present BVRCJHKs photometry of the optical afterglow of the gamma-ray burst GRB 021211 taken at the Magellan, MMT, and WIYN observatories between 0.7 and 50 days after the burst. We find an…
A possible low-mass type Ia supernova
- P. Ruiz-LapuenteD. Jeffery R. Canal
- 1 October 1993
Physics
IN the standard model for type Ia supernovae1, a massive white dwarf in a binary system accretes matter from the companion star until it reaches the Chandrasekhar mass (the stability limit for…
