SNe 2013K and 2013am: observed and physical properties of two slow, normal Type IIP events
L. Tomasella, E. Cappellaro, M. L. Pumo +28
We present one year of optical and near-infrared photometry and spectroscopy of the Type IIP SNe 2013K and 2013am. Both objects are affected by significant extinction, due to their…
OGLE-2014-SN-073 as a fallback accretion powered supernova
Takashi J. Moriya, Giacomo Terreran, Sergei I. Blinnikov
We investigate the possibility that the energetic Type II supernova OGLE-2014-SN-073 is powered by a fallback accretion following the failed explosion of a massive star. Taking mas…
Jets in Hydrogen-poor Super-luminous Supernovae: Constraints from a Comprehensive Analysis of Radio Observations
D. L. Coppejans, R. Margutti, C. Guidorzi +16
The energy source powering the extreme optical luminosity of hydrogen-stripped Superluminous Supernovae (SLSNe-I) is not known, but recent studies have highlighted the case for a c…
Improved constraints on H0 from a combined analysis of gravitational-wave and electromagnetic emission from GW170817
C. Guidorzi, R. Margutti, D. Brout +17
The luminosity distance measurement of GW170817 derived from GW analysis in Abbott et al. 2017 (here, A17:H0) is highly correlated with the measured inclination of the NS-NS system…
A kilonova as the electromagnetic counterpart to a gravitational-wave source
S. J. Smartt, T. -W. Chen, A. Jerkstrand +118
Gravitational waves were discovered with the detection of binary black hole mergers and they should also be detectable from lower mass neutron star mergers. These are predicted to…
Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm
G. Terreran, M. L. Pumo, T. -W. Chen +41
We present our study of OGLE-2014-SN-073, one of the brightest Type II SN ever discovered, with an unusually broad lightcurve combined with high ejecta velocities. From our hydrody…
Supernovae 2016bdu and 2005gl, and their link with SN 2009ip-like transients: another piece of the puzzle
A. Pastorello, C. S. Kochanek, M. Fraser +52
Supernova (SN) 2016bdu is an unusual transient resembling SN 2009ip. SN 2009ip-like events are characterized by a long-lasting phase of erratic variability which ends with two lumi…
