FlowWalker: A Memory-efficient and High-performance GPU-based Dynamic Graph Random Walk Framework

Kavli Affiliate: Jing Wang | First 5 Authors: Junyi Mei, Shixuan Sun, Chao Li, Cheng Xu, Cheng Chen | Summary: Dynamic graph random walk (DGRW) emerges as a practical tool for capturing structural relations within a graph. Effectively executing DGRW on GPU presents certain challenges. First, existing sampling methods demand a pre-processing buffer, causing substantial […]

Searching for Hyper-compact star clusters in the Milky Way using LAMOST and Gaia

Kavli Affiliate: Huawei Zhang | First 5 Authors: Hao Wu, Haibo Yuan, Yilun Wang, Zexi Niu, Huawei Zhang | Summary: During the early merger of the Milky Way, intermediate-mass black holes in merged dwarf galaxies may have been ejected from the center of their host galaxies due to gravitational waves, carrying some central stars along. […]

Geometric deformation and redshift structure caused by plane gravitational waves

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Chao-Jun Feng, , , | Summary: The curved spacetime induced by gravitational waves can give rise to visual effects such as geometric distortions and redshift structures in the observed image. By establishing a mapping from the object’s surface coordinates to the observer’s screen coordinates, we […]

Extracting Clean and Balanced Subset for Noisy Long-tailed Classification

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, He Zhao, Zhen Li, Tongliang Liu, Dandan Guo | Summary: Real-world datasets usually are class-imbalanced and corrupted by label noise. To solve the joint issue of long-tailed distribution and label noise, most previous works usually aim to design a noise detector to distinguish the noisy […]

eDIG-CHANGES II: Project Design and Initial Results on NGC 3556

Kavli Affiliate: Jing Wang | First 5 Authors: Jiang-Tao Li, Li-Yuan Lu, Zhijie Qu, Robert A. Benjamin, Joel N. Bregman | Summary: The extraplanar diffuse ionized gas (eDIG) represents ionized gases traced by optical/UV lines beyond the stellar extent of galaxies. We herein introduce a novel multi-slit narrow-band spectroscopy method to conduct spatially resolved spectroscopy […]

LiDAR-Guided Cross-Attention Fusion for Hyperspectral Band Selection and Image Classification

Kavli Affiliate: Jing Wang | First 5 Authors: Judy X Yang, Jun Zhou, Jing Wang, Hui Tian, Wee Chung Liew | Summary: The fusion of hyperspectral and LiDAR data has been an active research topic. Existing fusion methods have ignored the high-dimensionality and redundancy challenges in hyperspectral images, despite that band selection methods have been […]

INvestigations of massive Filaments ANd sTar formation (INFANT). I. Core Identification and Core Mass Function

Kavli Affiliate: Ke Wang | First 5 Authors: Yu Cheng, Xing Lu, Patricio Sanhueza, Hauyu Baobab Liu, Qizhou Zhang | Summary: Filamentary structures are ubiquitously found in high-mass star-forming clouds. To investigate the relationship between filaments and star formation, we carry out the INFANT (INvestigations of massive Filaments ANd sTar formation) survey, a multi-scale, multi-wavelength […]

The Rise of Faint, Red AGN at $z>4$: A Sample of Little Red Dots in the JWST Extragalactic Legacy Fields

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Dale D. Kocevski, Steven L. Finkelstein, Guillermo Barro, Anthony J. Taylor, Antonello CalabrĂ² | Summary: We present a sample of 341 "little red dots" (LRDs) spanning the redshift range $zsim2-11$ using data from the CEERS, PRIMER, JADES, UNCOVER and NGDEEP surveys. These sources are likely heavily-reddened AGN […]
