Testing Source Dependence in Gravitational-Wave Tests of General Relativity with Mutual Information
Yi-Fan Wang
Phenomenological deviation parameters used in gravitational-wave tests of general relativity need not represent universal fundamental properties of the sources. Instead, a deviatio…
Singularities of regular black holes and the monodromy method for asymptotic quasinormal modes
Chen Lan, Yi-Fan Wang
We use the monodromy method to investigate the asymptotic quasinormal modes of regular black holes based on the explicit Stokes portraits. We find that, for regular black holes wit…
Broad search for gravitational waves from subsolar-mass binaries through LIGO and Virgo's third observing run
Alexander H. Nitz, Yi-Fan Wang
We present a search for gravitational waves from the coalescence of binaries which contain at least one subsolar mass component using data from the LIGO and Virgo observatories thr…
4-OGC: Catalog of gravitational waves from compact-binary mergers
Alexander H. Nitz, Sumit Kumar, Yi-Fan Wang +5
We present the fourth Open Gravitational-wave Catalog (4-OGC) of binary neutron star (BNS), binary black hole (BBH) and neutron star-black hole (NSBH) mergers. The catalog includes…
Tests of Gravitational-Wave Birefringence with the Open Gravitational-Wave Catalog
Yi-Fan Wang, Stephanie M. Brown, Lijing Shao +1
We report the results of testing gravitational-wave birefringence using the largest population of gravitational-wave events currently available. Gravitational-wave birefringence, w…
Semi-classical predictions of cosmological wave-packets from ridge-lines
Chen Lan, Yi-Fan Wang
We introduce a concept of ridge-lines to investigate the semi-classical prediction from wave-packets with arbitrary width in conventional quantum mechanics and the Wheeler--DeWitt…
Search for gravitational waves from the coalescence of sub-solar mass binaries in the first half of Advanced LIGO and Virgo's third observing run
Alexander H. Nitz, Yi-Fan Wang
We present a search for gravitational waves from the coalescence of sub-solar mass black hole binaries using data from the first half of Advanced LIGO and Virgo's third observing r…
3-OGC: Catalog of gravitational waves from compact-binary mergers
Alexander H. Nitz, Collin D. Capano, Sumit Kumar +5
We present the third Open Gravitational-wave Catalog (3-OGC) of compact-binary coalescences, based on the analysis of the public LIGO and Virgo data from 2015 through 2019 (O1, O2,…
Search for gravitational waves from the coalescence of sub-solar mass and eccentric compact binaries
Alexander H. Nitz, Yi-Fan Wang
We present the first search for gravitational waves from sub-solar mass compact-binary mergers which allows for non-negligible orbital eccentricity. Sub-solar mass black holes are…
Search for gravitational waves from high-mass-ratio compact-binary mergers of stellar mass and sub-solar mass black holes
Alexander Harvey Nitz, Yi-Fan Wang
We present the first search for gravitational waves from the coalescence of stellar mass and sub-solar mass black holes with masses between and $0.01…
Searching for primordial black holes with stochastic gravitational-wave background in the space-based detector frequency band
Yi-Fan Wang, Qing-Guo Huang, Tjonnie G. F. Li +1
Assuming that primordial black holes compose a fraction of dark matter, some of them may accumulate at the center of galaxy and perform a prograde or retrograde orbit against the g…
Science with the TianQin observatory: Preliminary results on massive black hole binaries
Hai-Tian Wang, Zhen Jiang, Alberto Sesana +8
We investigate the prospects of detecting gravitational waves from coalescing massive black hole binaries in the Universe with the TianQin observatory, a space-based gravitational…
Dynamically Assisted Schwinger Effect at Strong Coupling with Its Holographic Extension
Chen Lan, Yi-Fan Wang, Huifang Geng +1
At strong-coupling and weak-field limit, the scalar Schwinger effect is studied by the field-theoretical method of worldline instantons for dynamic fields of single-pulse and sinus…
Integrable Minisuperspace Models with Liouville Field: Energy Density Self-Adjointness and Semiclassical Wave Packets
Alexander A. Andrianov, Chen Lan, Oleg O. Novikov +1
The homogeneous cosmological models with a Liouville scalar field are investigated in classical and quantum context of Wheeler-DeWitt geometrodynamics. In the quantum case of quint…

Sai Wang, Yi-Fan Wang, Dong-Mei Xia
We investigate the constraints on the sum of neutrino masses () using the most recent cosmological data, which combines the distance measurement from baryonic acoustic oscill…
Hawking Radiation: A Comparison of Pure-state and Thermal Descriptions
Yi-Fan Wang
The cases of the Hawking radiation field being described by a pure state and by the usual thermal state are compared within the CGHS dilaton gravity model. The field-strength fluct…

Taking into account the mass splittings between three active neutrinos, we investigate impacts of dark energy on constraining the total neutrino mass by using recent cos…
Smoothing methods comparison for CMB E- and B-mode separation
Yi-Fan Wang, Kai Wang, Wen Zhao
The anisotropies of the B-mode polarization in the cosmic microwave background radiation play a crucial role for the study of the very early Universe. However, in the real observat…
