KMT-2022-BLG-1818Lb,c: A Cold Super-Jupiter with a Saturn Sibling

Kavli Affiliate: Subo Dong | First 5 Authors: Hongyu Li, Jiyuan Zhang, Cheongho Han, Weicheng Zang, Youn Kil Jung | Summary: We present the discovery and analysis of the sixth microlensing two-planet system, KMT-2022-BLG-1818Lb,c, detected by a follow-up program targeting high-magnification events. Both planets are subject to the well-known ”Close/Wide” degeneracy, although for the first […]

From First Draft to Final Insight: A Multi-Agent Approach for Feedback Generation

Kavli Affiliate: Xian Chen | First 5 Authors: Jie Cao, Chloe Qianhui Zhao, Xian Chen, Shuman Wang, Christian Schunn | Summary: Producing large volumes of high-quality, timely feedback poses significant challenges to instructors. To address this issue, automation technologies-particularly Large Language Models (LLMs)-show great potential. However, current LLM-based research still shows room for improvement in […]

SHELLQs. Bridging the gap: JWST unveils obscured quasars in the most luminous galaxies at z > 6

Kavli Affiliate: John D. Silverman | First 5 Authors: Yoshiki Matsuoka, Masafusa Onoue, Kazushi Iwasawa, Kentaro Aoki, Michael A. Strauss | Summary: The unprecedented sensitivity of the James Webb Space Telescope (JWST) has uncovered a surprisingly abundant population of mildly obscured, low-luminosity active galactic nuclei (AGNs) in the epoch of reionization (EoR). However, the link […]

Testing Thermal-Relic Dark Matter with a Dark Photon Mediator

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, , , , | Summary: In light of recent DAMIC-M results, we present the status of thermal-relic dark matter $chi$ coupled to a kinetically-mixed dark photon $A^prime$. In the predictive "direct annihilation" regime, $m_{A’} > m_chi$, the relic abundance depends on the kinetic mixing parameter, […]

CAPERS-LRD-z9: A Gas Enshrouded Little Red Dot Hosting a Broad-line AGN at z=9.288

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Anthony J. Taylor, Vasily Kokorev, Dale D. Kocevski, Hollis B. Akins, Fergus Cullen | Summary: We present CAPERS-LRD-z9, a little red dot (LRD) which we confirm to be a $z=9.288$ broad-line AGN (BLAGN). First identified as a high-redshift LRD candidate from PRIMER NIRCam photometry, follow-up NIRSpec/PRISM spectroscopy […]

The Eccentricity Distribution of Warm Sub-Saturns in TESS

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Tyler R. Fairnington, Jiayin Dong, Chelsea X. Huang, Emma Nabbie, George Zhou | Summary: We present the eccentricity distribution of warm sub-Saturns (4-8 Re, 8-200 day periods) as derived from an analysis of transit light curves from NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. We use the […]
