The Hidden Evolution of Gamma-Ray Burst Jets Revealed by Gravitational Waves
Gerardo Urrutia, Fabio De Colle, Agnieszka Janiuk +2
Gamma-ray burst (GRB) jets can propagate through massive stars, where the high opacity of the stellar envelope traps electromagnetic radiation and limits observations of the jet at…
Bayesian parameter estimation for the Core-bounce phase of Rapidly Rotating Core-Collapse Supernovae in real interferometric data
Emmanuel Avila, Michele Zanolin, Javier M. Antelis +1
We present a novel methodology to estimate the ratio of kinetic to gravitational potential energy in core-collapse supernova progenitors and to assess the equation of state (EOS) u…
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…
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…
Residual neural networks to classify the high frequency emission in core-collapse supernova gravitational waves
Manuel D. Morales, Javier M. Antelis, Claudia Moreno
We present a new methodology to explore the morphology of the High Frequency Feature (HFF), i.e., the dominant, rising-frequency GW emission from a proto-neutron star in core-colla…
