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…
Transition from Outside-in to Inside-Out at : Evidence from Radial Profiles of Specific Star Formation Rate based on JWST/HST
Jie Song, Enci Wang, Cheng Jia +7
By combining high-resolution observations from JWST and HST, we have measured the stellar masses, star formation rates (SFRs), and multi-wavelength morphologies of galaxies in the…
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…
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…
Updated Metallicity Diagnostics for Precision Oxygen Abundance Measurements in High-redshift Galaxies with JWST
Shihong Liu, Yu Rong, Tie Li +7
Recent work has demonstrated that widely used strong-line oxygen abundance indicators, such as O3N2, , and , suffer from large uncertainties when applied…
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…
