Modeling of Radio Supernovae: Including the Effects of Inhomogeneities and Radiative Cooling

The Astrophysical Journal
The presence of inhomogeneities in a spatially unresolved source is often hard to establish. This limits the accuracy with which the source properties can be determined.

Hydrogen-rich to stripped-envelope: observational continuity and biases in CCSNe

Frontiers in Astronomy and Space Sciences
Although historically classified into discrete subclasses, there is growing evidence that indicates that core-collapse supernovae (CCSNe) categories often overlap, reflecting continuous variations in progenitor structure, mass-loss history, and ...

The contribution of Type IA supernovae to the galactic iron abundances [PDF]

, 1993
The thermonuclear explosion of a mass-accreting white dwarf in a close binary system is thought to be at the origin of Type Ia supernovae. Standard models, which ignite carbon at densities higher than 2-4 x 10 exp 9 g/cu cm, give, however, a large ...

Supernova Siblings and Spectroscopic Host Galaxy Properties

The Astrophysical Journal
Over the past century, supernova (SN) searches have detected multiple supernovae (SNe) in hundreds of individual galaxies. So-called SN siblings discovered in the same galaxy present an opportunity to constrain the dependence of the properties of SNe on ...

A Modern Approach to Searching for Late-time X-Ray Emission in Type Ib/c Supernovae

I present the progress both scientific and infrastructural that I have made while working on this search for late-time circumstellar interaction in type Ib/c supernovae.

An Extensive Hubble Space Telescope Study of the Offset and Host Light Distributions of Type I Superluminous Supernovae

The Astrophysical Journal
We present an extensive Hubble Space Telescope rest-frame UV imaging study of the locations of Type I superluminous supernovae (SLSNe) within their host galaxies.

In LIGO’s Sight? Vigorous Coherent Gravitational Waves from Cooled Collapsar Disks

The Astrophysical Journal Letters
We present the first numerical study of gravitational waves (GWs) from collapsar disks, using state-of-the-art 3D general relativistic magnetohydrodynamic simulations of collapsing stars.

Candidates for historical supernovae and their comparison against known Chinese records [PDF]

, 2003
In this MSc thesis, possible/probable supernova remnants associated with possible/probable historical supernovae are discussed and advancements in knowledge surrounding possible remnants associated with historical supernovae older than about a thousand ...
