Parameter Estimation Horizon of Core-Collapse Supernovae with a Network of Gravitational-Wave Detectors
Almat Akhmetali, Y. Sultan Abylkairov, Solange Nunes +3
Core-collapse supernovae are among the most promising yet still undetected sources of gravitational waves. A future detection would provide a direct view of the physical processes…
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…
Joint Detection and Characterization of the Standing Accretion Shock Instability for Core-Collapse Supernovae with cWB XP
Vicente Sierra, Zidu Lin, Michelle Zanolin +3
The most sensitive to-date multimessenger detection of the standing accretion shock instability in real interferometric data is presented, which quantitatively identifies the prese…
Quantification of the parameter estimation error from Rotating Core Collapse supernovae
Claudia Moreno, Javier M. Antelis, Michele Zanolin
In this paper, we perform parameter estimation with an analytical model to simulate the gravitational wave emission during the core bounce phase of a rapidly rotating core collapse…
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…
