Three-dimensional distribution of ejecta in Supernova 1987A at 10 000 days
J. Larsson, C. Fransson, J. Spyromilio +19
Due to its proximity, SN 1987A offers a unique opportunity to directly observe the geometry of a stellar explosion as it unfolds. Here we present spectral and imaging observations…
Superluminous supernova 2015bn in the nebular phase: evidence for the engine-powered explosion of a stripped massive star
M. Nicholl, E. Berger, R. Margutti +25
We present nebular-phase imaging and spectroscopy for the hydrogen-poor superluminous supernova SN 2015bn, at redshift z=0.1136, spanning +250-400 d after maximum light. The light…
Long-duration superluminous supernovae at late times
A. Jerkstrand, S. J. Smartt, C. Inserra +13
Nebular-phase observations and spectral models of Type Ic superluminous supernovae are presented. LSQ14an and SN 2015bn both display late-time spectra similar to galaxy-subtracted…
A stubbornly large mass of cold dust in the ejecta of Supernova 1987A
M. Matsuura, E. Dwek, M. J. Barlow +33
We present new Herschel photometric and spectroscopic observations of Supernova 1987A, carried out in 2012. Our dedicated photometric measurements provide new 70 micron data and im…
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…
Supersolar Ni/Fe production in the Type IIP SN 2012ec
Anders Jerkstrand, Stephen J. Smartt, Jesper Sollerman +14
SN 2012ec is a Type IIP supernova (SN) with a progenitor detection and comprehensive photospheric-phase observational coverage. Here, we present Very Large Telescope and PESSTO obs…
