Black holes with conical infinity in gravitational caloric theory
S. X. Tian, Zong-Hong Zhu
Whether gravitational caloric theory admits spherical black-hole solutions beyond Schwarzschild remains open. A well-defined black-hole solution requires both a regular horizon and…

Quantum noise, arising from the quantisation of electromagnetic field, has been a limiting noise source for current gravitational wave (GW) detectors. Squeezed vacuum modifies quan…
Decadal pre-explosion activity and circumstellar interaction in a supernova
Ting-Wan Chen, Amar Aryan, Sheng Yang +52
When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…
Thermal Deformation Reduction in High-Power Interferometry with Higher-Order Laser Modes
Liu Tao, Yuhang Zhao, Zong-Hong Zhu +1
Test-mass thermal noise is a limiting noise source for current and next-generation ground-based gravitational-wave observatories. Uniform-intensity higher-order laser beams, includ…
QPEs from Warped Disk Collisions with EMRIs: Brightness-Recurrence Diagram and Gravitational-Wave Follow-up
Bo-An Chen, Bei You, Giovanni Miniutti +11
Quasi-Periodic Eruptions (QPEs) display correlated long/short and strong/weak patterns that remain unexplained by existing flat-disk collision models. We propose that these feature…
Evidence for Intermediate-Mass Black Holes From Microlensing Signatures in CHIME/FRB catalog 2
Huan Zhou, Zhengxiang Li, Cheng-Gang Shao +4
Intermediate-mass black holes (IMBHs) are the missing link in the cosmic hierarchy of black holes, bridging the gap between stellar-mass black holes and supermassive ones. They als…
Inflation driven by a bare cosmological constant and its graceful exit
Chengsheng Mu, Shuxun Tian, Shuo Cao +1
Vacuum energy, a prediction of quantum field theory, manifests itself as a cosmological constant in general relativity. In this Letter, we propose a novel inflationary scenario dri…
A Candidate Open Cluster Pulsar: Timing Analysis of PSR J1922+3745 in NGC 6791
Xiao-Jin Liu, Ralph P. Eatough, Zhichen Pan +15
PSR J1922+3745 was recently identified as a radio pulsar toward the old open cluster NGC 6791, raising the prospect of the first pulsar associated with an open cluster. We report F…
Cosmic anisotropic hair of nonlocal RT gravity
Jiajun Zhou, Shuxun Tian, Zong-Hong Zhu
Nonlocal RT gravity has proven effective in explaining the late-time cosmic acceleration while remaining consistent with local gravity tests. However, most previous cosmological st…
Shaving off soft hairs and the black hole image memory effect

Among the known pulsars in our Galaxy, are found in globular clusters, but none has been confirmed in any open clusters yet, although they outnumber glo…
Gravitational lensing of gravitational waves: universal characteristics of strongly lensed memory waveforms
Ruanjing Zhang, Zhi-Chao Zhao, Shaoqi Hou +3
In this work, the strong lensing effect of the memory signal was considered. In the geometric optics limit, the lensed memory signal becomes oscillatory, while the unlensed is basi…
Reverberation lags viewed in hard X-rays from an accreting stellar-mass black hole
