On the formation of star-forming galaxies having anomalously low-metallicity regions: the role of galaxy interaction and CGM/IGM accretion
Yibo Cao, Zhizheng Pan
Gas accretion from both the circum-galactic medium (CGM)/inter-galatic medium (IGM) and interacting companion galaxy can dilute the gas phase metallicity of a galaxy. However, thei…
The H concentration of local star-forming galaxies: implications for galaxy structure formation
Zhizheng Pan, Xianzhong Zheng, Xu Kong
In this work, we present a study on the H emission line flux concentration of 3098 low-redshift star-forming galaxies (SFGs) using the MaNGA data available in the Data Release…
A Glimpse of Satellite Galaxies in the Milky Way with the 2.5-meter Wide Field Survey Telescope (WFST): Bootes III and Draco
Chao Yang, Zhizheng Pan, Min Fang +34
We carry out deep imaging of the Milky Way satellite galaxies, Bootes III and Draco, with WFST as one pilot observing program to demonstrate the capability of WFST. Combining catal…
Searching for Nearby Diffuse Dwarf Galaxies in the COSMOS Field
Dongdong Shi, XianZhong Zheng, Zhizheng Pan +5
It remains challenging to systematically survey nearby diffuse dwarf galaxies and address the formation mechanism of this population distinguishing from regular ones. We carry out…
