Haonan Zheng, Shihong Liao, Liang Gao, Fangzhou Jiang, | Summary: [[{“value”:”We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultra-diffuse galaxies (UDGs). We identify 181 UDGs and find their properties closely match observations. The total masses of EAGLE UDGs range from ${sim}5times 10^{8}~M_{odot}$ to ${sim}2times 10^{11}~M_{odot}$, indicating that they are […]

Kavli Affiliate: Huawei Zhang | First 5 Authors: Yongkang Sun, Yang Huang, Jifeng Liu, Haozhu Fu, Huawei Zhang | Summary: Hypervelocity stars (HVSs) represent a unique class of objects capable of escaping the gravitational pull of the Milky Way due to extreme acceleration events, such as close encounters with the supermassive black hole at the […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Weijun Zhuang, Qizhang Li, Xin Li, Ming Liu, Xiaopeng Hong | Summary: Temporal Action Detection and Moment Retrieval constitute two pivotal tasks in video understanding, focusing on precisely localizing temporal segments corresponding to specific actions or events. Recent advancements introduced Moment Detection to unify these two […]
Kavli Affiliate: Lile Wang | First 5 Authors: Xiaoyu Zhang, Yuxiao Yi, Lile Wang, Zhi-Qin John Xu, Tianhan Zhang | Summary: In astrophysical simulations, nuclear reacting flows pose computational challenges due to the stiffness of reaction networks. We introduce neural network-based surrogate models using the DeePODE framework to enhance simulation efficiency while maintaining accuracy and […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zihao Wu, Luis C. Ho, , , | Summary: Recent studies suggest that numerous intermediate-mass black holes (IMBHs) may wander undetected across the Universe, emitting little radiation. These IMBHs largely preserve their birth masses, offering critical insights into the formation of heavy black hole seeds and […]
Shubo Li, Ran Li, Kaihao Wang, Zixiang Jia, Xiaoyue Cao | Summary: [[{“value”:”Previous studies, based on precise modeling of a gravitationally lensing image, have identified what may be a extremely compact, dark perturber in the well-known lensing system SDSSJ0946+1006 (the "Jackpot"). Its remarkable compactness challenges the standard cold dark matter (CDM) paradigm. In this paper, […]
Kavli Affiliate: Ran Wang | First 5 Authors: Haiming Wang, Mert Unsal, Xiaohan Lin, Mantas Baksys, Junqi Liu | Summary: We introduce Kimina-Prover Preview, a large language model that pioneers a novel reasoning-driven exploration paradigm for formal theorem proving, as showcased in this preview release. Trained with a large-scale reinforcement learning pipeline from Qwen2.5-72B, Kimina-Prover […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Josep V. Arnau, Màrius Josep Fullana i Alfonso, , | Summary: The gravitational capture of a small compact object by a supermassive black hole is one of the most intriguing sources of gravitational waves to be detected by space-borne observatories. Modeling gravitational waves […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kazutaka Kimura, Kohei Inayoshi, Kazuyuki Omukai, , | Summary: Direct collapse of pristine gas in early galaxies is a promissing pathway for forming supermassive black holes (BHs) powering active galactic nuclei (AGNs) at the epoch of reionization (EoR). This seeding mechanism requires suppression of molecular hydrogen (H$_2$) […]
