Kavli Affiliate: Lijing Shao | First 5 Authors: Hai-Tian Wang, Garvin Yim, Xian Chen, Lijing Shao, | Summary: After the final stage of the merger of two black holes, the ringdown signal takes an important role on providing information about the gravitational dynamics in strong field. We introduce a novel time-domain (TD) approach, predicated on […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhu-Heng Yao, Sen Yang, Wei-Jian Guo, Yong-Jie Chen, Yu-Yang Songsheng | Summary: Over the past three decades, multiple reverberation mapping (RM) campaigns conducted for the quasar PG 2130+099 have exhibited inconsistent findings with time delays ranging from $sim$10 to $sim$200 days. To achieve a comprehensive understanding […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Mouxiang Chen, Lefei Shen, Zhuo Li, Xiaoyun Joy Wang, Jianling Sun | Summary: Foundation models have emerged as a promising approach in time series forecasting (TSF). Existing approaches either fine-tune large language models (LLMs) or build large-scale time-series datasets to develop TSF foundation models. However, these methods […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Mouxiang Chen, Lefei Shen, Zhuo Li, Xiaoyun Joy Wang, Jianling Sun | Summary: Foundation models have emerged as a promising approach in time series forecasting (TSF). Existing approaches either repurpose large language models (LLMs) or build large-scale time series datasets to develop TSF foundation models for universal […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Hai Yang, Feng Yuan, , , | Summary: Wind is believed to be widespread in various black hole accretion flows. However, unlike the wind from thin disks, which have substantial observational evidence, the wind from hot accretion flows is difficult to observe due to the extremely high […]
Kavli Affiliate: Jing Wang | First 5 Authors: Dongheng Qian, Jing Wang, , , | Summary: Coherent information quantifies the transmittable quantum information through a channel and is directly linked to the channel’s quantum capacity. In the context of dynamical purification transitions, scrambling dynamics sustain extensive and positive coherent information at low measurement rates, but […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Qian Yang, Paul J. Green, Xue-Bing Wu, Michael Eracleous, Linhua Jiang | Summary: "Changing-look quasars" (CLQs), discovered less than a decade ago, show dramatic, rapid changes in optical/UV continuum and broad line emission. The majority of CLQs have been found dimming as "turn-off" CLQs because most selection […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Jeffrey D. McKaig, Shobita Satyapal, Ari Laor, Nicholas P. Abel, Sara M. Doan | Summary: Forbidden collisionally excited optical atomic transitions from high ionization potential (IP$geq$54.8,eV) ions, such as Ca$^{mathrm{4+}}$, Ne$^{mathrm{4+}}$, Fe$^{mathrm{6+}}$, Fe$^{mathrm{10+}}$, Fe$^{mathrm{13+}}$, Ar$^{mathrm{9+}}$, and S$^{mathrm{11+}}$, are known as optical coronal lines (CLs). The spectral energy […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Yuhao Du, Zhuo Li, Pengyu Cheng, Xiang Wan, Anningzhe Gao | Summary: Large Language Models (LLMs) have become a focal point in the rapidly evolving field of artificial intelligence. However, a critical concern is the presence of toxic content within the pre-training corpus of these models, which […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Yuxun Guo, Xiaohui Liu, Feng Yuan, , | Summary: We study the forward-backward azimuthal angular correlations of hadrons in association with multi-particle production in the central rapidity region in proton-proton collisions at the LHC. We apply the nucleon energy-energy correlator framework, where the spinning gluon distribution introduces […]
