Representation Theorems for Actual Powers over Two-Agent General Concurrent Game Frames
Zixuan Chen, Fengkui Ju, Thomas Ågotnes
One of the most well-known connections between logic and games is Pauly's representation theorem: the induced powers of individuals and coalitions in concurrent game frames corresp…
Testing General Relativity with Binary Lens Microlensing Events
Xinyang Jin, Shuo Cao, Xuanni Chen +3
Einstein's General Relativity (GR), which has been precisely tested on galaxy and solar system scales, is still poorly constrained in extremely weak gravitational fields (with dime…
Revisiting the Hubble Tension with DESI DR2 Baryon Acoustic Oscillation Observations and Machine Learning Methods
Chenfa Zheng, Shuo Cao, Wuzheng Guo +4
One of the key unresolved questions in modern cosmology is the Hubble tension, which arises from the inconsistency between determinations of the Hubble constant () based on ne…
Null test of general relativity based on gravitational waves
Dawen Chen, Zeyuan Kang, Zhoujian Cao
Several hundreds of gravitational wave events have been detected. They are good tools to investigate various fundamental problems, including tests of general relativity (GR) theory…
Supernova origin of galactic turbulence revealed by superbubbles
Fanyi Meng, Chao-Wei Tsai, Jingwen Wu +13
Supernovae (SNe) are among the leading candidates for powering galactic-scale turbulence. SNe drive expanding shells of neutral atomic hydrogen (HI) known as superbubbles. Due to t…
LenNet: Direct Detection and Localization of Strong Gravitational Lenses in Wide-Field Sky Survey Images
Pufan Liu, Hui Li, Ziqi Li +9
Strong gravitational lenses are invaluable tools for addressing fundamental questions in astrophysics, from the nature of dark matter to the expansion of the universe. While curren…
