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…
From the Early Slope to Curvature: Future Prospects and challenges for Astrophysical Parameter Estimation Using the Core-Collapse Supernova High-Frequency Feature
Alejandro Casallas-Lagos, Marek SzczepaÅczyk, Michele Zanolin +1
Gravitational-wave (GW) signals from core-collapse supernovae (CCSNe) contain both stochastic and deterministic components. Among these, the High-Frequency Feature (HFF), associate…
Classifying the nuclear equation of state in LVK interferometric noise through core-collapse supernova gravitational-wave signatures using convolutional neural networks
Alejandro Casallas-Lagos, Marek J. SzczepaÅczyk, Michele Zanolin +4
This paper presents a convolutional neural network (CNN) approach to classifying the nuclear equation of state (EOS). As illustrative examples, we use five two-dimensional core-col…
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…
