Time-Varying Potassium in High-Resolution Spectra of the Type Ia Supernova 2014J
M. L. Graham, S. Valenti, B. J. Fulton +9
We present a time series of the highest resolution spectra yet published for the nearby Type Ia supernova (SN) 2014J in M82. They were obtained at 11 epochs over 33 days around pea…
PESSTO : survey description and products from the first data release by the Public ESO Spectroscopic Survey of Transient Objects
S. J. Smartt, S. Valenti, M. Fraser +99
The Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) began as a public spectroscopic survey in April 2012. We describe the data reduction str…
SN 2012ec: mass of the progenitor from PESSTO follow-up of the photospheric phase
C. Barbarino, M. Dall'Ora, M. T. Botticella +32
We present the results of a photometric and spectroscopic monitoring campaign of SN 2012ec, which exploded in the spiral galaxy NGC 1084, during the photospheric phase. The photome…
OGLE-2013-SN-079: a lonely supernova consistent with a helium shell detonation
C. Inserra, S. A. Sim, L. Wyrzykowski +31
We present observational data for a peculiar supernova discovered by the OGLE-IV survey and followed by the Public ESO Spectroscopic Survey for Transient Objects. The inferred reds…
Early-time light curves of Type Ib/c supernovae from the SDSS-II Supernova Survey
F. Taddia, J. Sollerman, G. Leloudas +6
We analyse the early-time optical light curves (LCs) of 20 Type Ib/c supernovae (SNe Ib/c) from the Sloan Digital Sky Survey (SDSS) SN survey II, aiming to study their properties a…
The Type IIb SN 2011dh - Two years of observations and modelling of the lightcurves
M. Ergon, A. Jerkstrand, J. Sollerman +14
We present optical and near-infrared (NIR) photometry and spectroscopy as well as modelling of the lightcurves of the Type IIb supernova (SN) 2011dh. Our extensive dataset spans tw…
