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…
The Superluminous Transient ASASSN-15lh as a Tidal Disruption Event from a Kerr Black Hole
G. Leloudas, M. Fraser, N. C. Stone +47
When a star passes within the tidal radius of a supermassive black hole, it will be torn apart. For a star with the mass of the Sun () and a non-spinning black hole with a…
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…
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…
