A Gravitational-Wave Perspective on Neutron-Star Seismology [PDF]

open access: yesUniverse, 2021
We provide a bird’s-eye view of neutron-star seismology, which aims to probe the extreme physics associated with these objects, in the context of gravitational-wave astronomy.

Constraint on Hybrid Stars with Gravitational Wave Events [PDF]

open access: yesUniverse, 2020
Motivated by the recent discoveries of compact objects from LIGO/Virgo observations, we study the possibility of identifying some of these objects as compact stars made of dark matter called dark stars, or the mix of dark and nuclear matters called ...

Neutron Star Mergers and the Quark Matter Equation of State [PDF]

open access: yesEPJ Web of Conferences, 2022
As neutron stars merge they can approach very high nuclear density. Here, we summarized recent results for the evolution and gravitational wave emission from binary-neutron star mergers using a a variety of nuclear equations of state with and without a ...

Detection and parameter estimation of gravitational waves from binary neutron-star mergers in real LIGO data using deep learning

open access: yesPhysics Letters B, 2021
One of the key challenges of real-time detection and parameter estimation of gravitational waves from compact binary mergers is the computational cost of conventional matched-filtering and Bayesian inference approaches.

Neutron star as a mirror for gravitational waves [PDF]

open access: yesAstrophysics and Space Science, 2020
Gravitational wave (GW) has become one of the most active fields in physics and astronomy since the first direct detection of GW event in 2015. As is well known, multiple images of GW events are possible through the gravitational lenses. Here, we propose a novel mirror imaging mechanism for GW events different from the gravitational lens.

Real-time detection of gravitational waves from binary neutron stars using artificial neural networks

open access: yesPhysics Letters B, 2020
The groundbreaking discoveries of gravitational waves from binary black-hole mergers [1–3] and, most recently, coalescing neutron stars [4] started a new era of Multi-Messenger Astrophysics and revolutionized our understanding of the Cosmos.
