Why are optical coronal lines faint in active galactic nuclei?

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 […]

Detecting AI Flaws: Target-Driven Attacks on Internal Faults in Language Models

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 […]

Long Range Energy-energy Correlator at the LHC

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 […]

Prompt-Softbox-Prompt: A free-text Embedding Control for Image Editing

Kavli Affiliate: Jing Wang | First 5 Authors: Yitong Yang, Yinglin Wang, Jing Wang, Tian Zhang, | Summary: Text-driven diffusion models have achieved remarkable success in image editing, but a crucial component in these models-text embeddings-has not been fully explored. The entanglement and opacity of text embeddings present significant challenges to achieving precise image editing. […]

Search for the $Σ(1380)1/2^-$ state in $Λ^+_c to γ π^+ Λ$ decay by triangle singularity

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Yu-Fei Wang, Bo-Chao Liu, Fei Huang, | Summary: In this work, we investigate the resonance production in $Lambda^+_c to gamma pi^+ Lambda$ decay through the triangle singularity (TS) mechanism, within an effective Lagrangian approach. We find that the appropriate loop decay process could develop a […]

From Halos to Galaxies. VI. Improved halo mass estimation for SDSS groups and measurement of the halo mass function

Kavli Affiliate: Yingjie Peng | First 5 Authors: Dingyi Zhao, Yingjie Peng, Yipeng Jing, Xiaohu Yang, Luis C. Ho | Summary: In $Lambda$CDM cosmology, galaxies form and evolve in their host dark matter (DM) halos. Halo mass is crucial for understanding the halo-galaxy connection. The abundance matching (AM) technique has been widely used to derive […]

The MAGPI Survey: the evolution and drivers of gas turbulence in intermediate-redshift galaxies

Kavli Affiliate: Yingjie Peng | First 5 Authors: Yifan Mai, Scott M. Croom, Emily Wisnioski, Sam P. Vaughan, Mathew R. Varidel | Summary: We measure the ionised gas velocity dispersions of star-forming galaxies in the MAGPI survey ($zsim0.3$) and compare them with galaxies in the SAMI ($zsim0.05$) and KROSS ($zsim1$) surveys to investigate how the […]
