A Spatially Resolved HI Survey of Seyfert Galaxies: the Role of AGN Feedback in Shaping Atomic Gas Reservoirs
Ruitian Li, Xin Wang, Daizhong Liu +19
Active galactic nucleus (AGN) feedback is a key ingredient in galaxy evolution, yet its impact on the cold atomic gas reservoir -- the neutral hydrogen (HI) phase -- remains poorly…
HI-detected Dwarf Galaxies in the FASHI Survey: Insights from Single- and Double-Peaked Emission-Line Samples
Cheng Cheng, Jia-Sheng Huang, Wei Du +4
We present a sample of low HI mass dwarf galaxies () detected by The FAST All Sky HI Survey (FASHI) project. Due to the faint and irregular morphology of…
A negative stellar massgaseous metallicity gradient relation of dwarf galaxies modulated by stellar feedback
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Baryonic cycling is reflected in the spatial distribution of metallicity within galaxies, yet gas-phase metallicity distribution and its connection with other properties of dwarf g…
Intrinsic shape variation of quiescent galaxies from redshift 2.5 to 0.5
Lijun Chen, Hong-Xin Zhang
According to the standard inside-out galaxy formation scenario, galaxies first form a dense core and then gradually assemble their outskirts. This implies that galaxies with simila…
Dwarf Galaxy Integral-field Survey (DGIS): survey overview and the result of global mass-metallicity relation
Xin Li, Yong Shi, Fuyan Bian +11
Low-mass galaxies are the building blocks of massive galaxies in the framework of hierarchical structure formation. To enable detailed studies of galactic ecosystems in dwarf galax…
Ultra Diffuse Dwarf Galaxies Hosting Pseudo-bulges
Yu Rong, Hong-Xin Zhang, Cheng Cheng +5
By analyzing data from DESI Legacy Imaging Survey of the dwarf galaxies in the Arecibo Legacy Fast Alfa Survey, we have identified five ultra-diffuse galaxies (UDGs) featuring cent…
