Linear Gravitational Wave Memory Through the Window of Core-Collapse Supernovae
Colter J. Richardson, Anthony Mezzacappa, Haakon Andresen +1
Low-frequency gravitational waves ( 50 Hz) from core-collapse supernovae are becoming more important for current and future gravitational wave studies. This frequency…
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…
A Three-Dimensional Exploration of Magnetic Fields, Rotation, and Shock Revival in a Core-Collapse Supernova Progenitor
Liubov Kovalenko, Evan O'Connor, Haakon Andresen +1
We present three-dimensional hydrodynamic and magnetohydrodynamic core-collapse supernova simulations of a rapidly rotating, high-compactness progenitor to investigate…
Black Hole Supernovae Outcomes Across a Wide Progenitor Range
Oliver Eggenberger Andersen, Evan O'Connor, Liubov Kovalenko +2
Black hole supernovae (BHSNe), the term we use for core-collapse events in which black hole (BH) formation occurs after shock revival but before the explosion is complete, have eme…
Assessing a Template-Based Approach for Core-Collapse Supernova Gravitational-Wave Detection
Haakon Andresen, Bella Finkel
Gravitational waves from core-collapse supernovae are a promising yet challenging target for detection due to the stochastic and complex nature of these signals. Conventional detec…
