Type Ic supernovae, the explosions after the core collapse of massive stars that have previously lost their hydrogen and helium envelopes, are particularly interesting because of their link with long-duration gamma ray bursts. Although indications exist that these explosions are aspherical, direct evidence has been missing. Late-time observations of supernova SN 2003jd, a luminous type Ic supernova, provide such evidence. Recent Subaru and Keck spectra reveal double-peaked profiles in the… Expand

Anisotropies in Core Collapse Supernovae
Core-collapse supernovae are the final stage of the evolution of massive stars. When these have previously lost their hydrogen and helium envelopes, the supernova explosion is classified as Type Ic.Expand

Abstract The properties of the Supernovae discovered in coincidence with long-duration Gamma-ray Bursts and X-Ray Flashes are reviewed, and compared to those of SNe for which GRBs are not observed.Expand
A non-spherical core in the explosion of supernova SN 2004dj
Multi-epoch spectropolarimetry of a classic type II-P supernova reveals the abrupt appearance of significant polarization when the inner core is first exposed in the thinning ejecta (∼90 days after explosion), suggesting that a strongly non-spherical explosion may be a generic feature of core-collapse supernovae of all types.

The broad-lined Type Ic SN 2012ap and the nature of relativistic supernovae lacking a gamma-ray burst detection
We present ultraviolet, optical, and near-infrared observations of SN 2012ap, a broad-lined Type Ic supernova in the galaxy NGC 1729 that produced a relativistic and rapidly decelerating outflowExpand
Radio Observations of a Sample of Broad-line Type IC Supernovae Discovered by PTF/IPTF: A Search for Relativistic Explosions
Long duration γ-ray bursts are a rare subclass of stripped-envelope core-collapse supernovae (SNe) that launch collimated relativistic outflows (jets). All γ-ray-burst-associated SNe areExpand
We present a theoretical model for supernova SN 2008D associated with the luminous X-ray transient 080109. The bolometric light curve and optical spectra of the SN are modeled based on the progenitorExpand
Nebular Phase Observations of the Type Ib Supernova 2008D/X-Ray Transient 080109 : Side-Viewed Bipolar Explosion
We present optical spectroscopic and photometric observations of supernova (SN) 2008D, associated with the luminous X-ray transient 080109, at >300 days after the explosion (nebular phases). We alsoExpand
Late-Time Radio Observations of 68 Type Ibc Supernovae: Strong Constraints on Off-Axis Gamma-Ray Bursts
We present late-time radio observations of 68 local Type Ibc supernovae, including six events with broad optical absorption lines ("hypernovae"). None of these objects exhibit radio emissionExpand
A neutron-star-driven X-ray flash associated with supernova SN 2006aj
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.

Pulsar-Driven Jets in Supernovae , Gamma-Ray Bursts , and the Universe
The bipolarity of Supernova 1987A can be understood through its very early light curve from the CTIO 0.4 m telescope and IUE FES and following speckle observations of the “Mystery Spot”. TheseExpand


A hypernova model for the supernova associated with the γ-ray burst of 25 April 1998
The discovery of the unusual supernova SN1998bw, and its possible association with the γ-ray burst GRB 980425, provide new insights into the explosion mechanism of very massive stars and the originExpand
A very energetic supernova associated with the γ-ray burst of 29 March 2003
Over the past five years evidence has mounted that long-duration (>2 s) γ-ray bursts (GRBs)—the most luminous of all astronomical explosions—signal the collapse of massive stars in our Universe. ThisExpand
Collapsars: Gamma-ray bursts and explosions in 'failed supernovae'
Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued evolution of rotating helium stars, Mα 10 M☉, in which iron-core collapse does not produce a successful outgoingExpand
A carbon–oxygen star as progenitor of the type Ic supernova 1994I
SUPERNOVAE are classified observationally as type I (which have no hydrogen emission lines in their optical spectra) or type II (which do have hydrogen lines), and are further subdivided1 into typesExpand
