A Most Energetic Type Ic Supernova: SN 2003L [PDF]

International Astronomical Union Colloquium, 2005
SummaryWe present extensive radio observations of SN2003L, the most luminous and energetic Type Ic radio supernova with the exception of SN 1998bw. Using radio data, we are able to constrain the physical parameters of the supernova, including the velocity and energy of the fastest ejecta, the temporal evolution of the magnetic field, and the density ...

Modeling Type Ic Supernovae with tardis: Hidden Helium in SN 1994I? [PDF]

The Astrophysical Journal, 2021
Abstract Supernovae (SNe) with photospheric spectra devoid of hydrogen and helium features are generally classified as SNe Ic. However, there is ongoing debate as to whether helium can be hidden in the ejecta of SNe Ic (that is, helium is present in the ejecta, but produces no obvious features in the spectra).

SN 2005at − A neglected type Ic supernova at 10 Mpc [PDF]

Astronomy & Astrophysics, 2014
We present a photometric and spectroscopic study of a reddened type Ic supernova (SN) 2005at. We report our results based on the available data of SN 2005at, including late-time observations from the Spitzer Space Telescope and the Hubble Space Telescope. In particular, late-time mid-infrared observations are something rare for type Ib/c SNe.

A Search for Relativistic Ejecta in a Sample of ZTF Broad-lined Type Ic Supernovae

The Astrophysical Journal, 2023
The dividing line between gamma-ray bursts (GRBs) and ordinary stripped-envelope core-collapse supernovae (SNe) is yet to be fully understood.

Type Ia Supernovae: An Examination of Potential Progenitors and the Redshift Distribution [PDF]

, 1997
We examine the possibility that supernovae type Ia (SN Ia) are produced by white dwarfs accreting from Roche-lobe filling evolved companions, under the assumption that a strong optically thick stellar wind from accretor is able to stabilize the mass ...

A `Hypernova' model for SN 1998bw associated with gamma-ray burst of 25 April 1998 [PDF]

, 1998
The discovery of the peculiar supernova (SN) 1998bw and its possible association with the gamma-ray burst (GRB) 980425$^{1,2,3}$ provide new clues to the understanding of the explosion mechanism of very massive stars and to the origin of some classes of ...

Discovery of a Relativistic Stripped-envelope Type Ic-BL Supernova at z = 2.83 with JWST

The Astrophysical Journal Letters
We present James Webb Space Telescope (JWST) NIRCam and NIRSpec observations of a Type Ic supernova (SN Ic) and its host galaxy (JADES-GS+53.13533-27.81457) at z = 2.83. This SN (named SN 2023adta) was identified in deep JWST/NIRCam imaging from the JWST

Critical Tests of Leading Gamma Ray Burst Theories

Universe, 2022
It has been observationally established that supernovae (SNe) of Type Ic produce long duration gamma-ray bursts (GRBs) and that neutron star mergers generate short hard GRBs.
