Spectroscopic confirmation of high-redshift supernovae with the ESO VLT
C. Lidman, D. A. Howell, G. Folatelli +44
We present VLT FORS1 and FORS2 spectra of 39 candidate high-redshift supernovae that were discovered as part of a cosmological study using Type Ia supernovae (SNe Ia) over a wide r…
Type IIP Supernovae as Cosmological Probes: A SEAM Distance to SN 1999em
E. Baron, Peter Nugent, David Branch +1
Due to their intrinsic brightness, supernovae make excellent cosmological probes. We describe the SEAM method for obtaining distances to Type IIP supernovae (SNe IIP) and present a…
Early Spectra of Supernovae
E. Baron, Peter Nugent, David Branch +1
We briefly describe the current version of the PHOENIX code. We then present some results on the modeling of Type II supernovae and show that fits to observations can be obtained,…
Discovery of a Transient U-band Dropout in a Lyman-Break Survey: A Tidally-Disrupted Star at z = 3.3?
Daniel Stern, P. G. van Dokkum, Peter Nugent +8
We report the discovery of a transient source in the central regions of galaxy cluster Abell 267. The object, which we call "PALS1", was found in a survey aimed at identifying high…
Supernova / Acceleration Probe: A Satellite Experiment to Study the Nature of the Dark Energy
SNAP Collaboration, G. Aldering, W. Althouse +109
The Supernova / Acceleration Probe (SNAP) is a proposed space-based experiment designed to study the dark energy and alternative explanations of the acceleration of the Universe's…
GRB 020410: A Gamma-Ray Burst Afterglow Discovered by its Supernova Light
A. Levan, P. Nugent, A. Fruchter +19
We present the discovery and monitoring of the optical transient (OT) associated with GRB 020410. The fading OT was found by Hubble Space Telescope (HST) observations taken 28 and…
