Multi-band power color-color diagrams of three black hole X-ray binaries observed with Insight-HXMT
Shao-Feng Liu, Long Ji, Yanan Wang
Power color-color diagrams (PCCDs) provide a useful diagnostic tool for studying the evolution of outbursts in black hole X-ray binaries. In this paper, we present power color-colo…
Deep learning with hybrid frequency differencing and principal component analysis for 21-cm foreground and beam mitigation
Zitong Wang, Feng Shi, Le Zhang +5
Twenty-one-centimeter intensity mapping is a powerful probe of the large-scale distribution of neutral hydrogen (HI) and cosmological observables such as baryon acoustic oscillatio…
The complex kinematics of the young stars orbiting the supermassive black hole in the Galactic center can be explained by the presence of an intermediate mass companion of Sgr A
Xiaochen Zheng, Long Wang, Douglas N. C. Lin +2
The sub-parsec proximity around the Sgr A supermassive black hole (SMBH) in the center of the Milky Way contains an inner cluster of eccentric S-stars with randomly oriente…
Understanding the Fundamental Design Decisions of Retrieval-Augmented Generation Systems
Shengming Zhao, Yuchen Shao, Yuheng Huang +4
Retrieval-Augmented Generation (RAG) has emerged as a critical technique for enhancing large language model (LLM) capabilities. However, practitioners face significant challenges w…
Lunar ejecta as the missing piece to resolve the lunar cratering asymmetry
Hailiang Li, Xiaoping Zhang, Li-Yong Zhou
The leading-trailing asymmetry in lunar crater distribution provides a critical record of inner solar system dynamics, yet the long-standing discrepancy between the observed higher…
Numerical estimation of the capture ability of Neptunian mean motion resonances
Hailiang Li, Li-Yong Zhou, Xiaoping Zhang
Resonant populations of trans-Neptunian objects serve as crucial dynamical archives for unraveling the early migratory history of the Solar System. A quantitative assessment of the…
