Effective dynamics of Janis-Newman-Winicour spacetime
Faqiang Yuan, Shengzhi Li, Zhen Li +1
The effective dynamics of the Janis-Newman-Winicour spacetime inspired by loop quantum gravity is studied. Two different schemes are considered to regularize the Hamiltonian constr…
Explicit and covariant formula for thermodynamic volume in extended black hole thermodynamics
Yong Xiao, Yu-Xiao Liu, Yu Tian +1
In extended black hole thermodynamics, the cosmological constant and other couplings are treated as thermodynamic variables, yielding the first law $\tildeδM = T\tildeδS+Ω\tildeδJ…
Internal structure of Hayward black holes
Caiying Shao, Jun-Qi Guo, Yu Tian +1
Regular black holes, free of central singularities, provide an ideal laboratory for probing the geometric structure of spacetime. The global structure of some regular black holes,…
Search for planetary-mass ultra-compact binaries using data from the first part of the LIGO--Virgo--KAGRA fourth observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765
We present a search for gravitational waves from inspiraling, planetary-mass ultra-compact binaries using data from the first part of the fourth observing run of LIGO, Virgo and KA…
Periodic Gravitational Lensing with Oscillating Boson Stars
Xing-Yu Yang, Tan Chen, Rong-Gen Cai
We show that oscillating (real-scalar) boson stars generically host an \emph{oscillating radial caustic}. Sources near this caustic cross it every half period, thereby producing pe…
Dynamic and Thermodynamic Stability of Superconducting-superfluid Stars
Delong Kong, Yu Tian, Hongbao Zhang
We give a comprehensive analysis of the dynamic and thermodynamic stability of neutron stars composed of superconducting-superfluid mixtures within the Iyer-Wald formalism. We deri…
Directional Search for Persistent Gravitational Waves: Results from the First Part of LIGO-Virgo-KAGRA's Fourth Observing Run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765
The angular distribution of gravitational-wave power from persistent sources may exhibit anisotropies arising from the large-scale structure of the Universe. This motivates directi…
Loop Quantum Vector-Tensor Gravity and Its Spherically Symmetric Model
Shengzhi Li, Yongge Ma
The Hamiltoinian analysis of the vector-tensor theory of gravity is performed. The resulting geometrical dynamics is reformulated into the connection dynamics, with the real SU(2)-…
Constraining the gravitational-wave emission of core-collapse supernovae with ground-based detectors
Jingwang Diao, Xingjiang Zhu
A gravitational-wave background (GWB) arising from the superposition of numerous unresolved gravitational-wave signals has yet to be detected. Potential contributing sources to suc…
Deparametrization and quantization of scalar-tensor gravity and its cosmological model
Faqiang Yuan, Haida Li, Shengzhi Li +1
The degree of freedom of the scalar field in scalar-tensor gravity is employed as "time" to deparametrize the Hamiltonian constraint of the theory. The deparametrized system is the…
Fermionic Love number of Reissner-Nordström black holes
Xiankai Pang, Yu Tian, Hongbao Zhang +1
The tidal deformation of compact objects, characterised by their Love numbers, provides insights into the internal structure of neutron stars and black holes. While static bosonic…
The transverse-traceless gauge and the gauge problem of second order gravitational waves
Yadong Xue, Zhoujian Cao
The gauge problem arises in the second order gravitational waves due to the mode mixing. Here, we introduce the transverse-traceless (TT) gauge to cosmological backgrounds, and fin…
GW250114: testing Hawking's area law and the Kerr nature of black holes
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785
The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence o…
