Probing RLVR training instability through the lens of objective-level hacking
Yiming Dong, Kun Fu, Haoyu Li +5
Prolonged reinforcement learning with verifiable rewards (RLVR) has been shown to drive continuous improvements in the reasoning capabilities of large language models, but the trai…
Inferring neutron-star Love-Q relations from gravitational waves in the hierarchical Bayesian framework
Zhihao Zheng, Ziming Wang, Jinwen Deng +2
Despite the large uncertainties in the equation of state for neutron stars (NSs), a tight universal ``Love-Q'' relation exists between their dimensionless tidal deformability, ,…
Ringdown mode amplitudes of charged binary black holes
Zexin Hu, Daniela D. Doneva, Ziming Wang +4
The ringdown phase of the binary black hole (BBH) merger provides a clean and direct probe of strong-field gravity and tests of the nature of black holes. The quasinormal mode (QNM…
Anatomy of parameter-estimation biases in overlapping gravitational-wave signals: detector network
Ziming Wang, Dicong Liang, Lijing Shao
With the significantly improved sensitivity and a wider frequency band, the next-generation gravitational-wave (GW) detectors are anticipated to detect GW signals per y…
Lightweight posterior construction for gravitational-wave catalogs with the Kolmogorov-Arnold network
Wenshuai Liu, Yiming Dong, Ziming Wang +1
Neural density estimation has seen widespread applications in the gravitational-wave (GW) data analysis, which enables real-time parameter estimation for compact binary coalescence…
Constraining Fermionic Dark Matter with Galactic Neutron Stars
Jianyuan Luo, Dicong Liang, Lijing Shao
Dark matter (DM) remains one of the most significant open questions in modern physics, with its nature and interactions largely unexplored. In this study, we investigate the behavi…
Vetting quark-star models with gravitational waves in the hierarchical Bayesian framework
Ziming Wang, Yong Gao, Dicong Liang +2
The recent discovery of gravitational waves (GWs) has opened a new avenue for investigating the equation of state (EOS) of dense matter in compact stars, which is an outstanding pr…
Unveiling the existence of nontensorial gravitational-wave polarizations from individual supermassive black hole binaries with pulsar timing arrays
Dicong Liang, Siyuan Chen, Chao Zhang +1
With the strong evidence for a gravitational wave (GW) background in the nanohertz frequency band from pulsar timing arrays, the detection of continuous GWs from individual superma…
Dynamic instability analysis for bumblebee black holes: the odd parity
Zhan-Feng Mai, Rui Xu, Dicong Liang +1
Spherical black-hole (BH) solutions have been found in the bumblebee gravity where a vector field nonminimally couples to the Ricci tensor. We study dynamic (in)stability associate…
The Impact of Spin in Compact Binary Foreground Subtraction for Estimating the Residual Stochastic Gravitational-wave Background in Ground-based Detectors

Stochastic gravitational-wave (GW) background (SGWB) contains information about the early Universe and astrophysical processes. The recent evidence of SGWB by pulsar timing arrays…
Impact of overlapping signals on parameterized post-Newtonian coefficients in tests of gravity
Yixuan Dang, Ziming Wang, Dicong Liang +1
Gravitational waves have been instrumental in providing deep insights into the nature of gravity. Next-generation detectors, such as the Einstein Telescope, are predicted to have a…
New limits on the local Lorentz invariance violation of gravity in the Standard-Model Extension with pulsars
Yiming Dong, Ziming Wang, Lijing Shao
Lorentz Violation (LV) is posited as a possible relic effect of quantum gravity at low energy scales. The Standard-Model Extension provides an effective field-theoretic framework f…
Probing nontensorial gravitational waves with a next-generation ground-based detector network
Jierui Hu, Dicong Liang, Lijing Shao
In General Relativity, there are only two polarizations for gravitational waves. However, up to six polarizations are possible in a generic metric theory of gravity. Therefore, mea…
