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. […]

Microlensing near macro-caustics

Kavli Affiliate: Paul L. Schechter | First 5 Authors: Luke Weisenbach, Timo Anguita, Jordi Miralda-Escudé, Masamune Oguri, Prasenjit Saha | Summary: Microlensing near macro-caustics is a complex phenomenon in which swarms of micro-images produced by micro-caustics form on both sides of a macro-critical curve. Recent discoveries of highly magnified images of individual stars in massive […]

Milky Way-est: Cosmological Zoom-in Simulations with Large Magellanic Cloud and Gaia-Sausage-Enceladus Analogs

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Deveshi Buch, Ethan O. Nadler, Risa H. Wechsler, Yao-Yuan Mao, | Summary: We present Milky Way-est, a suite of 20 cosmological cold-dark-matter-only zoom-in simulations of Milky Way (MW)-like host halos. Milky Way-est hosts are selected such that they: ($i$) are consistent with the MW’s measured halo […]
