Kavli Affiliate: Anna Frebel | First 5 Authors: Xiaowei Ou, Lina Necib, Andrew Wetzel, Anna Frebel, Jeremy Bailin | Summary: Recent measurements of the Milky Way rotation curve found a sharp decline at around $15$-$20$ kpc from the center of the Galaxy, suggesting that the Galactic dark matter halo is much less massive than predicted […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, , , , | Summary: The James Webb Space Telescope has detected massive black holes (BHs) with masses of $sim 10^{6-8}~M_odot$ within the first billion years of the universe. One of the remarkable findings is the identification of "Little Red Dots" (LRDs), a unique class […]
Kavli Affiliate: Eric D. Miller | First 5 Authors: Gerrit Schellenberger, Ralph Kraft, Paul Nulsen, Eric D. Miller, Marshall W. Bautz | Summary: The level and uncertainty of the particle induced background in CCD detectors plays a crucial role for future X-ray instruments, such as the Wide Field Imager (WFI) onboard Athena. To mitigate the […]

Kavli Affiliate: T. Higuchi | First 5 Authors: The Belle, Belle II Collaborations, :, I. Adachi, L. Aggarwal | Summary: We report a precise measurement of the ratio of branching fractions $mathcal{B}(Lambda_c^+to p K_S^0 pi^0)/mathcal{B}(Lambda_c^+to p K^- pi^+)$ using 980 fb$^{-1}$ of $e^+e^-$ data from the Belle experiment. We obtain a value of $mathcal{B}(Lambda_c^+to p […]
Kavli Affiliate: Yingjie Peng | First 5 Authors: Jing Dou, Yingjie Peng, Qiusheng Gu, Luis C. Ho, Alvio Renzini | Summary: Understanding the physical mechanisms that drive star formation is crucial for advancing our knowledge of galaxy evolution. We explore the interrelationships between key galaxy properties associated with star formation, with a particular focus on […]
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: Kejia Lee | First 5 Authors: Longfei Hao, Zhixuan Li, Faxin Shen, Yonghua Xu, Yuxiang Huang | Summary: In this paper, we present the linear decomposition method (LDM), which we developed to detect and analyze pulsar profile variations and mode changing behaviour. We developed LDM utilizing the likelihood function approach assuming the Gaussian […]
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 […]
