Supernova Cosmology and the ESSENCE project
Jesper Sollerman, Claudio Aguilera, Andy Becker +27
The proper usage of Type Ia supernovae (SNe Ia) as distance indicators has revolutionized cosmology, and added a new dominant component to the energy density of the Universe, dark…
Identification of the Red Supergiant Progenitor of Supernova 2005cs: Do the Progenitors of Type II-P Supernovae Have Low Mass?
Weidong Li, Schuyler D. Van Dyk, Alexei V. Filippenko +5
The stars that end their lives as supernovae (SNe) have been directly observed in only a handful of cases, due mainly to the extreme difficulty in identifying them in images obtain…
The Fall 2004 SDSS Supernova Survey
Masao Sako, Roger Romani, Josh Frieman +38
In preparation for the Supernova Survey of the Sloan Digital Sky Survey (SDSS) II, a proposed 3-year extension to the SDSS, we have conducted an early engineering and science run d…
The NICMOS Ultra Deep Field: Observations, Data Reduction, and Galaxy Photometry
Rodger I. Thompson, Garth Illingworth, Rychard Bouwens +10
This paper describes the observations and data reduction techniques for the version 2.0 images and catalog of the NICMOS Ultra Deep Field Treasury program. All sources discussed in…
Cepheid Calibrations from the Hubble Space Telescope of the Luminosity of Two Recent Type Ia Supernovae and a Re-determination of the Hubble Constant
Adam G. Riess, Weidong Li, Peter B. Stetson +6
We report observations of two nearby Type Ia supernovae (SNe Ia) for which observations of Cepheid variables in the host galaxies have been obtained with the Hubble Space Telescope…
The Deepest Supernova Search is Realized in the Hubble Ultra Deep Field Survey
Louis-Gregory Strolger, Adam G. Riess
The Hubble Ultra Deep Field Survey has not only provided the deepest optical and near infrared views of universe, but has enabled a search for the most distant supernovae to z~2.2.…
