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…
Exploring the Outer Solar System with the ESSENCE Supernova Survey
A. C. Becker, K. Arraki, N. A. Kaib +36
We report the discovery and orbit determination of 14 trans-Neptunian objects (TNOs) from the ESSENCE Supernova Survey difference imaging dataset. Two additional objects discovered…
Optical Spectroscopy of Type Ia Supernovae
T. Matheson, R. P. Kirshner, P. Challis +19
We present 432 low-dispersion optical spectra of 32 Type Ia supernovae (SNe Ia) that also have well-calibrated light curves. The coverage ranges from 6 epochs to 36 epochs of spect…
Spectral Identification of an Ancient Supernova using Light Echoes in the LMC
A. Rest, T. Matheson, S. Blondin +26
We report the successful identification of the type of the supernova responsible for the supernova remnant SNR 0509-675 in the Large Magellanic Cloud (LMC) using Gemini spectra of…
Asphericity in Supernova Explosions from Late-Time Spectroscopy
Keiichi Maeda, Koji Kawabata, Paolo A. Mazzali +15
Core-collapse supernovae (CC-SNe) are the explosions that announce the death of massive stars. Some CC-SNe are linked to long-duration gamma-ray bursts (GRBs) and are highly aspher…
Double-peaked Oxygen Lines Are not Rare in Nebular Spectra of Core-Collapse Supernovae
Maryam Modjaz, R. P. Kirshner, S. Blondin +2
Double-peaked oxygen lines in the nebular spectra of two peculiar Type Ib/c Supernovae (SN Ib/c) have been interpreted as off-axis views of a GRB-jet or unipolar blob ejections. He…
