Type Ic core-collapse supernova explosions evolved from very massive stars [PDF]

, 2013
We investigate the possibility of a super-luminous Type Ic core-collapse supernovae producing a large amount of 56Ni. Very massive stars with a main-sequence mass larger than 100 Msun and a metallicity 0.001 < Z < 0.004 are expected to explode as super ...

Superluminous Supernovae [PDF]

Space Science Reviews, 2018
Superluminous supernovae are a new class of supernovae that were recognized about a decade ago. Both observational and theoretical progress has been significant in the last decade.

Dust versus Supernova Cosmology [PDF]

, 2000
Here we present some critical discussions about the systematic uncertainty by dust extinction in the recent cosmological results of high-redshift Type Ia supernovae.

Observable signatures of dark photons from supernovae [PDF]

Journal of High Energy Physics, 2019
A dark photon is a well-motivated new particle which, as a component of an associated dark sector, could explain dark matter. One strong limit on dark photons arises from excessive cooling of supernovae.

Absolute-Magnitude Distributions and Light Curves of Stripped-Envelope Supernovae [PDF]

, 2006
The absolute visual magnitudes of three Type IIb, 11 Type Ib and 13 Type Ic supernovae (collectively known as stripped-envelope supernovae) are studied by collecting data on the apparent magnitude, distance, and interstellar extinction of each event ...

The Use of Multiwavelength Archival Observational Data for Scientific Discoveries: a Case of the Supernova Remnant Cassiopeia A

Open Astronomy, 2012
Most of the high-quality astronomical data after a proprietary period of typically one year are provided to open access, allowing researchers to complement their observations with the archival data in other wavelength bands, thus improving quality of the

Induced Gravitational Collapse, Binary-Driven Hypernovae, Long Gramma-ray Bursts and Their Connection with Short Gamma-ray Bursts

Universe, 2019
There is increasing observational evidence that short and long Gamma-ray bursts (GRBs) originate in different subclasses, each one with specific energy release, spectra, duration, etc, and all of them with binary progenitors.

The Carnegie Supernova Project: First Photometry Data Release of Low-Redshift Type Ia Supernovae [PDF]

, 2009
The Carnegie Supernova Project (CSP) is a five-year survey being carried out at the Las Campanas Observatory to obtain high-quality light curves of ~100 low-redshift Type Ia supernovae in a well-defined photometric system.

Supernovae sparked by dark matter in white dwarfs [PDF]

Physical Review D, 2019
It was recently demonstrated that asymmetric dark matter can ignite supernovae by collecting and collapsing inside lone sub-Chandrasekhar mass white dwarfs, and that this may be the cause of Type Ia supernovae.

Weighing Cosmological Models with SNe Ia and Gamma Ray Burst Redshift Data

Universe, 2019
Many models have been proposed to explain the intergalactic redshift using different observational data and different criteria for the goodness-of-fit of a model to the data. The purpose of this paper is to examine several suggested models using the same
