Kavli Affiliate: Lijing Shao | First 5 Authors: Rohan Dahale, Ilje Cho, Kotaro Moriyama, Kaj Wiik, Paul Tiede | Summary: We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astrophysical, and imaging effects. Leveraging the enhanced capabilities of the […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Yacheng Kang, Jin-Ping Zhu, Yu-Han Yang, Ziming Wang, Eleonora Troja | Summary: The recent detections of bright optical/infrared kilonova signals following two long-duration gamma-ray bursts (LGRBs), GRB 211211A and GRB 230307A, have significantly challenged the traditional classification of GRBs. These merger-driven LGRBs may represent a distinct GRB […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Alessandro Peca, Michael J. Koss, Roberto Serafinelli, Claudio Ricci, C. Megan Urry | Summary: We report the serendipitous discovery of an absorption feature at 4.8 keV in the NuSTAR spectra of ESP 39607, a Seyfert 2 galaxy at $z = 0.201$, observed in May 2023 and August […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Feng Yuan, Yifan Gao, Wenbin Wu, Keqing Wu, Xiaotong Guo | Summary: Accurate multi-modal medical image translation requires ha-rmonizing global anatomical semantics and local structural fidelity, a challenge complicated by intermodality information loss and structural distortion. We propose ABS-Mamba, a novel architecture integrating the Segment Anything Model […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Marcelo C. Vergara, Abbas Askar, Albrecht W. H. Kamlah, Rainer Spurzem, Francesco Flammini Dotti | Summary: Context. We present simulations of a massive young star cluster using textsc{Nbody6++GPU} and textsc{MOCCA}. The cluster is initially more compact than previously published models, with one million stars, a total mass […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Zhicheng He, Enci Wang, Luis C. Ho, Huiyuan Wang, Yong Shi | Summary: The Star-Forming Main Sequence (SFMS) serves as a critical framework for understanding galaxy evolution, highlighting the relationship between star formation rates (SFR) and stellar masses M_* across cosmic time. Despite its significance, the […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Jiangwei Xu, Heng Xu, Yanjun Guo, Jinchen Jiang, Bojun Wang | Summary: Fast radio bursts (FRBs) are luminous, dispersed millisecond-duration radio bursts whose origin is poorly known. Recent observations suggest that some FRBs may reside in binary systems, even though conclusive evidence remains elusive. Here we report […]

Kavli Affiliate: Xian Chen | First 5 Authors: Kohei Inayoshi, Jinyi Shangguan, Xian Chen, Luis C. Ho, Zoltan Haiman | Summary: Little red dots (LRDs) are a newly identified class of broad-line active galactic nuclei (AGN) with a distinctive v-shape spectrum characterized by red optical and blue UV continuum emission. Their high abundance at redshifts […]
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 […]
