On the Detectability and Measurement of Galactic Bars as a Function of Redshift
Yi-Xiao Lyu, Luis C. Ho, Zhao-Yu Li +1
The cosmic evolution of galactic bars offers key insights into the dynamical history of disk galaxies. However, studies of high-redshift bars are severely hampered by observational…
The Low- Splash Population in the Milky Way
Lais Borbolato, João A. S. Amarante, Hélio D. Perottoni +5
The Milky Way in-situ halo, also known as the Splash, consists of old (age 10 Gyr), metal-rich ([Fe/H] ), high- stars, i.e., thick disk-like chemistry, on halo-like…
CSST Preparations: Galaxy Completeness and Sérsic Profile Fitting across the Wide, Deep, and Extreme Fields
Ziqi Ma, Si-Yue Yu, Taotao Fang +3
The upcoming imaging survey of the Chinese Space-station Survey Telescope (CSST) will deliver high-resolution imaging of an unprecedented number of galaxies for galaxy studies. To…
Cold Gas Infall onto A Brightest Group Galaxy via A Gas-Rich Minor Merger
Ming-Yang Zhuang, Jinyi Shangguan, Yuan Bian +6
Dust and cold gas are not uncommon in nearby early-type galaxies (ETGs), and represent an important aspect of their evolution. However, their origin has been debated for decades. P…
Beyond Morphology: Challenges in Decomposing Massive Stellar Halos in Sombrero-like, Halo-Embedded Disk Galaxies
Wu-Tao He, Min Du, Zhao-Yu Li +1
Sombrero-like galaxies exhibit unique structural properties that challenge traditional photometric decomposition methods. In this study, we investigate their structural differences…
The Origin of the Gas and Its Low Star Formation Efficiency in Quiescent Galaxies
Yang A. Li, Luis C. Ho, Jinyi Shangguan +2
Quiescent galaxies (QGs) typically have little cold gas to form stars. The discovery of gas-rich QGs challenges our conventional understanding of the evolutionary paths of galaxies…
The PSF Smoothing Effect on Concentration-Related Parameters of High Redshift Galaxies in HST and JWST
Jia-Hui Wang, Zhao-Yu Li, Ming-Yang Zhuang +2
We perform a comprehensive investigation of the PSF smoothing effect on the measurement of concentration-related parameters (, Gini, ) of high redshift galaxies in the H…
