Color profiles of disk galaxies at - observed with JWST: Implications for outer-disk formation histories
Si-Yue Yu, Dewang Xu, Boris S. Kalita +4
We investigate the deconvolved color profiles of 223 disk galaxies at redshifts of -3 observed by the James Webb Space Telescope (JWST) as part of the Cosmic Evolution Early R…
IllustrisTNG in the HSC-SSP: No Shortage of Thin Disk Galaxies in TNG50
Dewang Xu, Hua Gao, Connor Bottrell +2
We perform a thorough analysis of the projected shapes of nearby galaxies in both observations and cosmological simulations. We implement a forward-modeling approach to overcome th…
JWST reveals a high fraction of disk breaks at
Dewang Xu, Si-Yue Yu
We analyzed the deconvolved surface brightness profiles of 247 massive and angularly large disk galaxies at to study high-redshift disk breaks, using F356W-band ima…
Strong spiral arms drive secular growth of pseudo bulges in disk galaxies
Si-Yue Yu, Dewang Xu, Luis C. Ho +2
Spiral-driven instabilities may drive gas inflow to enhance central star formation in disk galaxies. We investigate this hypothesis using the Sloan Digital Sky Survey (SDSS) in a s…
