Constraining Fermionic Dark Matter with Galactic Neutron Stars

Kavli Affiliate: Lijing Shao| First 5 Authors: Jianyuan Luo, Jianyuan Luo, , , | Summary:Dark matter (DM) remains one of the most significant open questions in modern physics, with its nature and interactions largely unexplored. In this study, we investigate the behavior of massive fermionic DM particles in the context of neutron stars (NSs), extending […]

ABS-Mamba: SAM2-Driven Bidirectional Spiral Mamba Network for Medical Image Translation

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 […]

Rapid formation of a very massive star >50000 $M_odot$ and subsequently an IMBH from runaway collisions. Direct N-body and Monte Carlo simulations of dense star clusters

Kavli Affiliate: Rainer Spurzem | Summary:Context. We present simulations of a massive young star cluster using textscNbody6++GPU and textscMOCCA. The cluster is initially more compact than previously published models, with one million stars, a total mass of $5.86 times 10^5~mathrmM_odot$, and a half-mass radius of $0.1~mathrmpc$. Aims. We analyse the formation and growth of a […]

Black Hole Envelopes in Little Red Dots

Kavli Affiliate: Kohei Inayoshi| First 5 Authors: Daisaburo Kido, Daisaburo Kido, , , | Summary:Recent observations by the James Webb Space Telescope have uncovered a population of compact, red object ($zsim 4text–7$) known as little red dots (LRDs). The presence of broad Balmer emission lines indicates active galactic nuclei powered by supermassive black holes (BHs), […]

Symmetry in Fundamental Parameters of Galaxies on the Star-forming Main Sequence

Kavli Affiliate: Luis Ho | 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 origin of the 0.3-0.4 dex dispersion in the SFMS remains a key unresolved question. Uncovering the origin […]

Periodic variation of magnetoionic environment of a fast radio burst source

Kavli Affiliate: Kejia Lee | 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 the detection of a 26.24$pm$0.02 day periodicity in Faraday rotation measure (RM) of an actively […]

The Emergence of Little Red Dots from Binary Massive Black Holes

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 […]
