Gravitational Waves due to Population III Core Collapse Supernovae

, 2012
Faculty Advisor: Professor Vuk MandicMy goal was to examine the accuracy of the claim in Sandick et al (2006) that LIGO would be able to observe Gravitational Waves emitted from the core collapse supernovae of Population III stars.This research was ...

A New Mechanism for Gravitational-Wave Emission in Core-Collapse Supernovae [PDF]

, 2006
We present a new theory for the gravitational wave signatures of core-collapse supernovae. Previous studies identified axisymmetric rotating core collapse, core bounce, postbounce convection, and anisotropic neutrino emission as the primary processes and

SN 2024abvb: A Type Icn Supernova in the Outskirts of Its Host Galaxy

The Astrophysical Journal
We present multiband photometric and spectroscopic observations of supernova (SN) 2024abvb, which exhibits early-time prominent photoionized narrow emission lines of C II superposed on a blue continuum.

The innermost zones of core collapse supernovae

, 2005
We achieve successful explosions (of otherwise non-explosive models) by enhancing the neutrino luminosity in two different ways. The resulting electron fraction Y_e in the innermost ejecta reaches or in some zones even exceeds 0.5.

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 ...

Astrophysics with Gravitational Wave Signals from Core-Collapse Supernovae [PDF]

, 2019
The next generation of gravitational wave detectors will improve the detection prospects for gravitational waves from core-collapse supernovae. The complex astrophysics involved in core-collapse supernovae pose a significant challenge to modeling such ...
