TL;DR: It is reported that the peculiar type Ib supernova SN 2006jc is spatially coincident with a bright optical transient that occurred in 2004, andSpectroscopic and photometric monitoring of the supernova leads us to suggest that the progenitor was a carbon-oxygen Wolf–Rayet star embedded within a helium-rich circumstellar medium.
Journal ArticleDOI
A neutron-star-driven X-ray flash associated with supernova SN 2006aj.

TL;DR: The results indicate that the supernova–GRB connection extends to a much broader range of stellar masses than previously thought, possibly involving different physical mechanisms: a ‘collapsar’ for the more massive stars collapsing to a black hole, and magnetic activity of the nascent neutron star for the less massive stars.
Journal ArticleDOI

TL;DR: It is suggested that all CC-SNe from stripped-envelope stars are aspherical explosions and that SNe accompanied by GRBs exhibit the highest degree of asphericity.
Journal ArticleDOI
An asymmetric energetic type Ic supernova viewed off-axis, and a link to gamma ray bursts.

TL;DR: Recent Subaru and Keck spectra reveal double-peaked profiles in the nebular lines of neutral oxygen and magnesium, different from those of known type Ic supernovae, with or without a gamma ray burst, and they can be understood if SN 2003jd was an aspherical axisymmetric explosion viewed from near the equatorial plane.
Journal ArticleDOI
Models for the type Ic hypernova SN 2003lw associated with GRB 031203

TL;DR: In this paper, the gamma-ray burst GRB 031203 at a redshift z = 0.1055 revealed a highly reddened Type Ic supernova, SN 2003lw, in its afterglow light.
