Observational Evidence for Anisotropic Metal Excess around Galaxies
Cheqiu Lyu, Enci Wang, Zeyu Chen +4
The exchange of matter and energy between galaxies and their surroundings drives the cosmic baryon cycle, yet mapping metal transport remains an observational challenge. While simu…
Stellar feedback drives the baryon deficiency in low-mass galaxies
Haoran Yu, Enci Wang, Zeyu Chen +8
Stellar feedback, as a key process regulating the baryon cycle, is thought to greatly redistribute baryonic material inside and outside the dark matter halos (DMHs), however the ob…
Cooler Phases of the Circumgalactic Medium Are More Centrally Concentrated: Constraints from Multiphase Absorption Lines
Weiwen Kong, Zeyu Chen, Enci Wang +7
We present a systematic study of the multiphase circumgalactic medium (CGM) around galaxies and quasars, traced by Ca II , Mg II , and C IV…
Where, What, Why, and Importance: Structured Defect Grounding for Text-to-Image Feedback
Huaisong Zhang, Hao Yu, Yuxuan Zhang +7
Despite generating increasingly photorealistic images, text-to-image (T2I) models still exhibit localized, subtle, and structurally complex failures. Diagnosing these failures requ…
First Statistical Detection of MgII-traced Cool Gas Outflows with JWST Towards Cosmic Dawn
Cheqiu Lyu, Haoran Yu, Enci Wang +9
Galactic-scale outflows are a crucial component of galaxy evolution, yet their properties in the early universe remain poorly constrained. We present the first statistical investig…
Central Concentration and Escape of Ionizing Photons in Galaxies at the Epoch of Reionization
Cheqiu Lyu, Enci Wang, Junxian Wang +9
Compact, low-mass galaxies with strong nebular emission are considered promising candidates for efficient ionizing photon production and escape. We present a spatially resolved ana…
