Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Haojie Hu, Kohei Inayoshi, Zoltan Haiman, Luis C. Ho, Ken Ohsuga | Summary: The James Webb Space Telescope (JWST) has revealed low-luminosity active galactic nuclei (AGNs) at redshifts of $zgtrsim 4-7$, many of which host accreting massive black holes (BHs) with BH-to-galaxy mass ($M_{rm BH}/M_{star}$) ratios exceeding […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Shuqi Fu, Fengwu Sun, Linhua Jiang, Xiaojing Lin, Jose M. Diego | Summary: We measure H$alpha$ luminosity functions (LFs) at redshifts $z sim 4.5$ and 6.3 using the JWST MAGNIF (Medium-band Astrophysics with the Grism of NIRCam In Frontier fields) survey. MAGNIF obtained NIRCam grism spectra with […]
Kavli Affiliate: Huawei Zhang | Summary:Utilizing Zwicky Transient Facility (ZTF) data and existing RR Lyrae stars (RRLs) catalogs, this study achieves the first calibration of the $P – φ_31 – R_21 – text[Fe/H]$ and $P-φ_31-A_2-A_1-text[Fe/H]$ relations in the ZTF photometric system for RRab and RRc stars. We also re-calibrate the period-absolute magnitude-metallicity (PMZ) and period-Wesenheit-metallicity […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Yuhao Du, Xiaoqi Jiao, Yiwen Guo, Yuege Feng | Summary: Selecting high-quality and diverse training samples from extensive datasets plays a crucial role in reducing training overhead and enhancing the performance of Large Language Models (LLMs). However, existing studies fall short in assessing the overall […]

Kavli Affiliate: Ruobing Dong | Summary:Late infall events challenge the traditional view that planet formation occurs without external influence. Here we present deep ALMA $^12$CO $J=2-1$ and SO $J_N=5_6-4_5$ observations toward AB Aurigae, a Class II disk system with strong signs of gravitational instability and ongoing planet formation. By applying Keplerian and anti-Keplerian masks, we […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Xuying Li, Zhuo Li, Yuji Kosuga, Victor Bian, | Summary: Large Language Models (LLMs) have demonstrated strong reasoning capabilities, but their safety under adversarial conditions remains a challenge. This study examines the impact of output length on the robustness of DeepSeek-R1, particularly in Forced Thinking scenarios. We […]

Kavli Affiliate: Yingjie Peng | Summary:We present the COSMOS Spectroscopic Redshift Compilation encompassing ~ 20 years of spectroscopic redshifts within a 10 deg$^2$ area centered on the 2 deg$^2$ COSMOS legacy field. This compilation contains 487,666 redshifts of 266,284 unique objects from 138 individual observing programs up to $z sim 8$ with median stellar mass […]
