Low-Frequency Gravitational Waves in Three-Dimensional Core-Collapse Supernova Models
Colter J. Richardson, Anthony Mezzacappa, Kya Schluterman +5
We discuss the low-frequency gravitational wave signals from three state-of-the-art three-dimensional core-collapse supernova models produced with the \textsc{Chimera} supernova co…
Detecting Gravitational Wave Memory in the Next Galactic Core-Collapse Supernova
Colter J. Richardson, Haakon Andresen, Anthony Mezzacappa +5
We present an approach to detecting (linear) gravitational wave memory in a Galactic core-collapse supernova using current interferometers. Gravitational wave memory is an importan…
Approximating General Relativity in Core-Collapse Supernova Simulations
Steven A. Fromm, Vassilios Mewes, O. E. Bronson Messer +3
We present formulations of effective potentials suitable for approximating general relativistic effects in Newtonian simulations of core-collapse supernovae. Assuming a spherically…
Gravitational Waves as a Probe of Core Collapse Supernova Progenitor Structure
R. Daniel Murphy, Elle Brinkman, Colter J. Richardson +5
We present the gravitational wave predictions from two-dimensional core collapse supernova (CCSN) simulations initiated from two nearly identical progenitors that have significantl…
Core Collapse Supernova Gravitational Wave Sourcing and Characterization based on Three-Dimensional Models
R. Daniel Murphy, Anthony Mezzacappa, Eric J. Lentz +1
We present for the first time an analysis of high-frequency gravitational wave (GW) emission from proto-neutron stars (PNS) in core collapse supernovae (CCSN) that combines spatial…
Dependence of the Reconstructed Core-Collapse Supernova Gravitational Wave High-Frequency Feature on the Nuclear Equation of State, in Real Interferometric Data
R. Daniel Murphy, Alejandro Casallas-Lagos, Anthony Mezzacappa +6
We present an analysis of gravitational wave (GW) predictions from five two-dimensional Core Collapse Supernova (CCSN) simulations that varied only in the Equation of State (EOS) i…
