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: Zhuo Li | First 5 Authors: Yuhao Du, Zhuo Li, Pengyu Cheng, Xiang Wan, Anningzhe Gao | Summary: Despite the substantial advancements in artificial intelligence, large language models (LLMs) remain being challenged by generation safety. With adversarial jailbreaking prompts, one can effortlessly induce LLMs to output harmful content, causing unexpected negative social impacts. […]
