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…
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. Szczepańczyk, 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…
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…
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…
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…
On the detectability of gravitational waves emitted from head-on collisions of -boson stars
Mariana Lira, Laura O. Villegas, Javier M. Antelis +3
In this work, we investigate head-on collisions of -boson stars, potential candidates for dark matter compact objects. We begin with a review of the general properties and fe…
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…
Generating tailored high frequency features in core collapse supernova gravitational wave signals applicable in LIGO interferometric studies
César Tiznado, Alejandro Casallas-Lagos, Javier M. Antelis +1
In this article, we introduce a methodology based on an analytical model of a damped harmonic oscillator subject to random forcing to generate transient gravitational wave signals.…
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…
