No Redshift Evolution in the Fe II/Mg II Flux Ratios of Quasars across Cosmic Time

Kavli Affiliate: Linhua Jiang | First 5 Authors: Danyang Jiang, Masafusa Onoue, Linhua Jiang, Samuel Lai, Eduardo Banados | Summary: The Fe II/Mg II emission line flux ratio in quasar spectra serves as a proxy for the relative Fe to alpha-element abundances in the broad line regions of quasars. Due to the expected different enrichment […]

Two Channels of Metal-Rich Compact Stellar System Formation: Starbursts Under High Ram Pressure vs. Tidal Stripping

Kavli Affiliate: Luis C. Ho | First 5 Authors: Yuan Bian, Min Du, Victor P. Debattista, Dylan Nelson, Mark A. Norris | Summary: Most galaxies follow well-defined scaling relations of metallicity and stellar mass; however, some outliers at the low mass end of the observed galaxy population exhibit unusually high metallicity for their mass. Understanding […]

A novel standard candle: collapsing axion stars

Kavli Affiliate: Lijing Shao | First 5 Authors: Haoran Di, Lijing Shao, Zhu Yi, Shi-Bei Kong, | Summary: The Hubble constant, $H_0$, is a crucial parameter in cosmology. However, various cosmic observations have produced differing posterior values for $H_0$, resulting in what is referred to as the $H_0$ tension. To resolve this discrepancy, utilizing other […]

PIP: Detecting Adversarial Examples in Large Vision-Language Models via Attention Patterns of Irrelevant Probe Questions

Kavli Affiliate: Jiansheng Chen | First 5 Authors: Yudong Zhang, Ruobing Xie, Jiansheng Chen, Xingwu Sun, Yu Wang | Summary: Large Vision-Language Models (LVLMs) have demonstrated their powerful multimodal capabilities. However, they also face serious safety problems, as adversaries can induce robustness issues in LVLMs through the use of well-designed adversarial examples. Therefore, LVLMs are […]

Neutron stars in the bumblebee theory of gravity

Kavli Affiliate: Lijing Shao | First 5 Authors: Peixiang Ji, Zhuhai Li, Lirui Yang, Rui Xu, Zexin Hu | Summary: Recently, theoretical studies on the bumblebee gravity model, a nonminimally-coupled vector-tensor theory that violates the Lorentz symmetry, have flourished, with a simultaneous increase in the utilization of observations to impose constraints. The static spherical solutions […]

Qihoo-T2X: An Efficiency-Focused Diffusion Transformer via Proxy Tokens for Text-to-Any-Task

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Ao Ma, Jiasong Feng, Dawei Leng, Yuhui Yin | Summary: The global self-attention mechanism in diffusion transformers involves redundant computation due to the sparse and redundant nature of visual information, and the attention map of tokens within a spatial window shows significant similarity. To address […]
