The nebular spectra of SN 2012aw and constraints on stellar nucleosynthesis from oxygen emission lines
A. Jerkstrand, S. J. Smartt, M. Fraser +4
We present nebular phase optical and near-infrared spectroscopy of the Type IIP supernova SN 2012aw combined with NLTE radiative transfer calculations applied to ejecta from stella…
The superluminous supernova PS1-11ap: bridging the gap between low and high redshift
M. McCrum, S. J. Smartt, R. Kotak +37
We present optical photometric and spectroscopic coverage of the superluminous supernova (SLSN) PS1-11ap, discovered with the Pan-STARRS1 Medium Deep Survey at z = 0.524. This intr…
Slowly fading super-luminous supernovae that are not pair-instability explosions
M. Nicholl, S. J. Smartt, A. Jerkstrand +57
Super-luminous supernovae that radiate more than 10^44 ergs per second at their peak luminosity have recently been discovered in faint galaxies at redshifts of 0.1-4. Some evolve s…
SN 2012ca: a stripped envelope core-collapse SN interacting with dense circumstellar medium
C. Inserra, S. J. Smartt, R. Scalzo +16
We report optical and near-infrared observations of SN 2012ca with the Public ESO Spectroscopy Survey of Transient Objects (PESSTO), spread over one year since discovery. The super…
Comparison of progenitor mass estimates for the type IIP SN 2012A
L. Tomasella, E. Cappellaro, M. Fraser +24
We present the one-year long observing campaign of SN 2012A which exploded in the nearby (9.8 Mpc) irregular galaxy NGC 3239. The photometric evolution is that of a normal type IIP…
Super Luminous Ic Supernovae: catching a magnetar by the tail
C. Inserra, S. J. Smartt, A. Jerkstrand +37
We report extensive observational data for five of the lowest redshift Super-Luminous Type Ic Supernovae (SL-SNe Ic) discovered to date, namely PTF10hgi, SN2011ke, PTF11rks, SN2011…
