On the nature of oscillating modes of proto-neutron stars
Dimitra Tseneklidou, Alejandro Torres-Forne, Pablo Cerda-Duran +2
Newborn proto-neutron stars (PNS) are potential targets of gravitational wave asteroseismology, the study of the (inner) structure of stars via their oscillation modes. To prepare…
Strongly interacting matter with criticality induced by modified excluded volume in core-collapse supernova simulations
Anil Kumar, Noshad Khosravi Largani, Stefan Typel +3
This article reviews critically the core-collapse supernova explosion mechanism associated with a sufficiently strong first-order phase transition from normal nuclear, in general h…
GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-Spin Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1783
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW…
Black Hole Spectroscopy and Tests of General Relativity with GW250114
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration
The binary black hole signal GW250114, the loudest gravitational wave detected to date, offers a unique opportunity to test Einstein's general relativity (GR) in the high-velocity,…
Self-consistent treatment of thermal effects in neutron-star post-mergers: observational implications for third-generation gravitational-wave detectors
Verónica Villa-Ortega, Ana Lorenzo-Medina, Juan Calderón Bustillo +4
We assess the impact of accurate, self-consistent modelling of thermal effects in neutron-star merger remnants in the context of third-generation gravitational-wave detectors. This…
Towards asteroseismology of neutron stars with physics-informed neural networks
Dimitra Tseneklidou, Alejandro Torres-Forne, Pablo Cerda-Duran
The study of the gravitational wave signatures of neutron star oscillations may provide important information of their interior structure and Equation of State (EoS) at high densit…
