Universal relations applied to proto-neutron star generated gravitational waves from three-dimensional core collapse supernova simulations

R. Daniel Murphy, Anthony Mezzacappa, Colter J. Richardson +3

Using asteroseismology techniques, several relations have been developed that relate the quasi-normal, non-radial oscillation mode frequencies of the proto-neutron star (PNS) to th…

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…

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…
