Gravitational caloric theory: From early dark energy to a wide variety of gravitational phenomena
S. X. Tian
We propose gravitational caloric theory (GCT) --- an extension of general relativity that features a vector field sourced by and non-minimally coupled to the fluid sector whi…
Degenerate Limits of Scalar-Tensor Gravity
Bekir BaytaÅ, Xiao-Kan Guo
The paper analyzes how scalar‑tensor gravity behaves when the spatial triad becomes degenerate, using a Hamiltonian connection‑dynamics approach to derive the resulting constraints…
Narrowband searches for continuous gravitational waves from known pulsars in the first two parts of the fourth LIGO--Virgo--KAGRA observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1853
Rotating non-axisymmetric neutron stars (NSs) are promising sources for continuous gravitational waves (CWs). Such CWs can, if detected, inform us about the internal structure and…
All-sky, all-frequency directional search for persistent gravitational-waves from Advanced LIGO's and Advanced Virgo's first three observing runs
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1627
We present the first results from an all-sky all-frequency (ASAF) search for an anisotropic stochastic gravitational-wave background using the data from the first three observing r…
Solving Hamiltonian Constraint Equation with Physics-Informed Neural Networks
Yu-Chen Zhou, Hao Ma, Zhoujian Cao +6
Numerical relativity (NR), solving Einstein equation numerically, plays an important role in source modelling for gravitational wave astronomy. Traditional methods for NR including…
GWTC-4.0: Methods for Identifying and Characterizing Gravitational-wave Transients
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1809
The Gravitational-Wave Transient Catalog (GWTC) is a collection of candidate gravitational-wave transient signals identified and characterized by the LIGO-Virgo-KAGRA Collaboration…
