ProWorld: Multi-View World Model with Proprioceptive Feedback for Closed-Loop Policy Evaluation
Zijun Wang, Tianyi Yan, Haokun Lin +12
Evaluating robot manipulation policies through repeated physical trials is costly. We study whether an action-conditioned world model can serve as a closed-loop test environment wh…
The Galactic disk structure revealed by Gaia XP spectra
Zhenkang Tang, Jianhui Lian, Jialong Zhou +1
The spatial structures of chemical populations constrain Galactic disk evolution and its underlying physical processes. Gaia XP spectra provide one of the largest spectroscopic sam…
The disrupted chemical enrichment history of the Milky Way driven by gas accretion
Jianhui Lian, Qinhao Shao, Min Du +4
As the only galaxy enabling temporally-resolved observations from an internal vantage point, the Milky Way as a galaxy offers unique insights into galactic chemical enrichment hist…
A Strong Stellar Age-Metallicity Gradient Relation in Nearby Dwarf Galaxies Driven by Stellar Migration and Environmental Quenching
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Stellar metallicity gradients () provide a fossil record of the assembly history of galaxies. We present an analysis of for 90 nearby low-mass galaxies u…
Evidence of radial-migration driven Galactic disc expansion with the U-shape stellar age profile
Jianhui Lian, Qinhao Shao, Yuze Zhao
Canonical theory predicts galaxies grow "inside-out", producing their observed negative radial age gradient. This picture is challenged by galaxies' `U-shaped' colour profiles -- i…
Vertical Structure of Local Disk Galaxies revealed by DESI Imaging Data
Nan Chen, Jianhui Lian, Yuze Zhao
The vertical structure of galactic disks is an important probe of disk assembly history. We investigate a sample of 79 local disk galaxies within 50 Mpc using data from the DESI Le…
The Extremely Metal Rich Knot of Stars at the Heart of the Galaxy
Hans-Walter Rix, Vedant Chandra, Gail Zasowski +15
We show with Gaia XP spectroscopy that extremely metal-rich stars in the Milky Way (EMR; ) - but only those - are largely confined to a tight "knot" at the center…
