CFHT MegaCam Two Deep Fields Imaging Survey (2DFIS) II: Decoding the Lensing Profile of a "Rotating" Cluster with Deep CFHT Imaging
Yicheng Li, Liping Fu, Wentao Luo +15
We present a multi-wavelength analysis of the galaxy cluster RXCJ0110.0+1358 (), a rotating cluster candidate, combining deep CFHT imaging, SDSS photometry, spectroscopic…
CFHT MegaCam Two Deep Fields Imaging Survey (2DFIS) I: Overview
Binyang Liu, Wentao Luo, Martin Kilbinger +14
We present the Two Deep Fields Imaging Survey (2DFIS), a wide-field imaging program conducted with the Canada-France-Hawaii Telescope (CFHT) targeting two astrophysically distinct…
Deploying Atmospheric and Oceanic AI Models on Chinese Hardware and Framework: Migration Strategies, Performance Optimization and Analysis
Yuze Sun, Wentao Luo, Yanfei Xiang +4
With the growing role of artificial intelligence in climate and weather research, efficient model training and inference are in high demand. Current models like FourCastNet and AI-…
Stochastic lensing of stars by ultralight dark matter halos
Andrew Eberhardt, Elisa Ferreira, Wentao Luo +2
Ultralight dark matter is an interesting dark matter candidate describing the lightest end of the mass parameter space. This model produces an oscillating granular pattern in halo…
Testing Cotton gravity as dark matter substitute with weak lensing
Geyu Mo, Qingqing Wang, Xin Ren +3
Harada proposed a modified theory of gravity called Cotton gravity, and argued that it successfully explains the rotation curves of galaxies without the need of dark matter. I…
