Gravitational-wave standard sirens and application in cosmology
Wen Zhao, Liang-Gui Zhu, Youjun Lu
The discovery of the gravitational-wave event GW170817 from a binary neutron star merger, together with its multi-wavelength electromagnetic counterparts, marks the beginning of th…
Distance Estimation and Sky Localization of Eccentric Double White Dwarf Binaries from Gravitational Wave Observations inside Globular Clusters
Yuetong Zhao, L. Hellström, Siqi Zhang +7
The cosmic distance scale is built on multiple different techniques for estimating distances in space that are often connected and dependent on multiple measurements and assumption…
Multiband gravitational wave observations of eccentric escaping binary black holes from globular clusters
Yuetong Zhao, Abbas Askar, Youjun Lu +7
Stellar-mass binary black holes (sBBHs) formed in globular clusters (GCs) are promising sources for multiband gravitational wave (GW) observations, particularly with low- and middl…
The diverse morphology of gravitational wave signals from merging neutron-star white-dwarf binaries
Shenghua Yu, Youjun Lu, C. Simon Jeffery +6
In sufficiently compact neutron star-white dwarf (NSWD) binary systems, orbital decay means the white dwarf eventually fills its shrinking Roche lobe, initiating a phase of mass tr…
Formation Channels of Gravitationally Resolvable Double White Dwarf Binaries Inside Globular Clusters
Lucas Hellström, MirosÅaw Giersz, Abbas Askar +6
Current gravitational wave detectors are sensitive to coalescing black holes and neutron stars. However, double white dwarfs (DWDs) have long been recognized as promising sources o…
Spin evolution and mass distribution of the Galactic Binary Neutron Stars
Qingbo Chu, Youjun Lu, Shenghua Yu
Binary neutron stars (BNSs) detected in the Milky Way have the total masses distributing narrowly around , while the BNS merger GW190425 detected via gravitatio…
