The most distant HI galaxies discovered by the 500 m dish FAST

Kavli Affiliate: Jing Wang | First 5 Authors: Hongwei Xi, Bo Peng, Lister Staveley-Smith, Bi-Qing For, Bin Liu | Summary: Neutral hydrogen (HI) is the primary component of the cool interstellar medium (ISM) and is the reservoir of fuel for star formation. Owing to the sensitivity of existing radio telescopes, our understanding of the evolution […]

Revisiting the fundamental metallicity relation with observation and simulation

Kavli Affiliate: Yingjie Peng | First 5 Authors: Chengyu Ma, Kai Wang, Enci Wang, Yingjie Peng, Haochen Jiang | Summary: The gas-phase metallicity of galaxies is regulated by multiple astrophysical processes, which makes it a crucial diagnostic of galaxy formation and evolution. Beyond the fundamental mass-metallicity relation, a debate about the secondary galaxy property to […]

Implementing Streaming algorithm and k-means clusters to RAG

Kavli Affiliate: Ke Wang | First 5 Authors: Haoyu Kang, Yuzhou Zhu, Yukun Zhong, Ke Wang, | Summary: Retrieval-augmented generation (RAG) has achieved great success in information retrieval to assist large models because it builds an external knowledge database. However, it also has many problems: it consumes a lot of memory because of the huge […]

Localized stem structures in quasi-resonant two-soliton solutions for the asymmetric Nizhnik-Novikov-Veselov system

Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Jiguang Rao, Jingsong He, Yi Cheng, | Summary: Elastic collisions of solitons generally have a finite phase shift. When the phase shift has a finitely large value, the two vertices of the (2+1)-dimensional 2-soliton are significantly separated due to the phase shift, accompanied by the […]

Spectral instability of black holes: relating the frequency domain to the time domain

Kavli Affiliate: Lijing Shao | First 5 Authors: Yiqiu Yang, Zhan-Feng Mai, Run-Qiu Yang, Lijing Shao, Emanuele Berti | Summary: Recent work has shown that the quasinormal mode spectrum of black holes is unstable under small perturbations (of order $epsilon$) of the radial potential, while the early time-domain ringdown waveform is only marginally affected. In […]
