Four GRB supernovae at redshifts between 0.4 and 0.8: The bursts GRB 071112C, 111228A, 120714B, and 130831A
(EDP Sciences, 2019)
Twenty years ago, GRB 980425/SN 1998bw revealed that long gamma-ray bursts (GRBs) are physically associated with broad-lined type-Ic supernovae (SNe). Since then more than 1000 long GRBs have been localized to high angular ...
Supernova 2008bk and its red supergiant progenitor
(American Astronomical Society, 2012)
Hemos obtenido pocos datos fotométricos y espectroscópicos de supernova (SN) 2008bk en NGC 7793, principalmente a 150 días después de la explosión. Nos parece que se trata de un tipo II-Plateau (II-P) SN que más se asemeja ...
On Type IIn/Ia-CSM supernovae as exemplified by SN 2012ca
(OXFORD UNIV PRESS, 2016-07)
We present the complete set of ultra-violet, optical and near-infrared photometry and spectroscopy for SN 2012ca, covering the period from 6 d prior to maximum light, until 531 d after maximum. The spectroscopic time series ...
Multiwavelength observations of the Type IIb supernova 2009mg
(WILEY-BLACKWELL, 2012-08)
We present Swift Ultra-Violet Optical Telescope and X-Ray Telescope (XRT) observations,
and visual wavelength spectroscopy of the Type IIb supernova (SN) 2009mg, discovered in
the Sb galaxy ESO 121-G26. The observational ...
The Highly Energetic Expansion of SN 2010bh Associated with GRB 100316D
(IOP Publishing, 2012-07)
We present the spectroscopic and photometric evolution of the nearby (z = 0.059) spectroscopically confirmed Type Ic supernova, SN 2010bh, associated with the soft, long-duration gamma-ray burst (X-ray flash) GRB 100316D. ...
SN 2012fr: Ultraviolet, Optical, and Near-infrared Light Curves of a Type Ia Supernova Observed within a Day of Explosion
(IOP Publishing, 2018-05)
We present detailed ultraviolet, optical, and near-infrared light curves of the Type Ia supernova (SN) 2012fr, which exploded in the Fornax cluster member NGC 1365. These precise high-cadence light curves provide a dense ...
SUPERNOVA 2008bk AND ITS RED SUPERGIANT PROGENITOR
(IOP PUBLISHING LTD, 2012-01)
We have obtained limited photometric and spectroscopic data for supernova (SN) 2008bk in NGC 7793, primarily at greater than or similar to 150 days after explosion. We find that it is a Type II-Plateau (II-P) SN that most ...
Multi-wavelength observations of supernova 2011ei: time-dependent classification of type iib and ib supernovae and implications for their progenitors
(2012)
We present X-ray, UV/optical, and radio observations of the stripped-envelope, core-collapse supernova (SN) 2011ei, one of the least luminous SNe IIb or Ib observed to date. Our observations begin with a discovery within ...
A Missing-link in the Supernova–GRB Connection: The Case of SN 2012ap
(The American Astronomical Society, 2015-06-01)
Gamma-ray bursts (GRBs) are characterized by ultra-relativistic outflows, while supernovae are generally
characterized by non-relativistic ejecta. GRB afterglows decelerate rapidly, usually within days, because their ...
