Morphological classification conveys abundant information on the formation, evolution, and environment of galaxies. In this work, we refine the two-step galaxy morphological classi…
A study of the merging dwarf galaxy VCC322
Lanyue Zhang, Yinghe Zhao, Hongxin Zhang
Galaxy interactions and mergers can enhance or reduce star formation, but a complete understanding of the involved processes is still lacking. The effect of dwarf galaxy mergers is…
An evolutionary continuum from nucleated dwarf galaxies to star clusters
Kaixiang Wang, Eric W. Peng, Chengze Liu +21
Systematic studies have revealed hundreds of ultra-compact dwarf galaxies (UCDs) in the nearby Universe. With half-light radii of approximately 10-100 parsecs and stellar mas…
Dwarf galaxies with the highest concentration are not thicker than ordinary dwarf galaxies
Lijun Chen, Hong-Xin Zhang, Zesen Lin +5
The formation mechanism of high-concentration dwarf galaxies is still a mystery. We perform a comparative study of the intrinsic shape of nearby low-mass galaxies with different st…
Strong [O III] λ5007 Compact Galaxies Identified from SDSS DR16 and Their Scaling Relations
Weiyu Ding, Hu Zou, Xu Kong +11
Green pea galaxies are a special class of star-forming compact galaxies with strong [O III]λ5007 and considered as analogs of high-redshift Lyα-emitting galaxies and potential sour…
Merger-induced star formation in low-metallicity dwarf galaxy NGC 4809/4810
Yulong Gao, Qiusheng Gu, Guilin Liu +5
The physical mechanisms driving starbursts in dwarf galaxies are unclear, and the effects of mergers on star formation in these galaxies are still uncertain. We explore how the mer…
Evolution of Non-parametric Morphology of Galaxies in the JWST CEERS Field at 0.8-3.0
Yao Yao, Jie Song, Xu Kong +3
Galaxy morphology is one of the most fundamental ways to describe galaxy properties, but the morphology we observe may be affected by wavelength and spatial resolution, which may i…
Sciences with the 2.5-meter Wide Field Survey Telescope (WFST)
WFST Collaboration, Tinggui Wang, Guilin Liu +60
The Wide Field Survey Telescope (WFST) is a dedicated photometric surveying facility being built jointly by the University of Science and Technology of China and the Purple Mountai…
Variability of Young Stellar Objects in the Perseus Molecular Cloud
Xiao-Long Wang, Min Fang, Gregory J. Herczeg +5
We present an analysis of 288 young stellar objects (YSOs) in the Perseus Molecular Cloud that have well defined and -band lightcurves from the Zwicky Transient Facility. Of…
Unveiling the formation of NGC 2915 with MUSE: A counter-rotating stellar disk embedded in a disordered gaseous environment
Yimeng Tang, Bojun Tao, Hong-Xin Zhang +6
NGC 2915 is a unique nearby galaxy that is classified as an isolated blue compact dwarf based on its optical appearance but has an extremely extended H i gas disk with prominent Sd…
Discovery of a Bimodal Environmental Distribution of Compact Ellipticals in the Local Universe
Guangwen Chen, Hong-Xin Zhang, Xu Kong +5
Low-mass compact stellar systems (CSSs; 10 M) are thought to be a mixed bag of objects with various formation mechanisms. Previous surveys of CSSs…
Distributed YSOs in the Perseus Molecular Cloud from the Gaia and LAMOST Surveys
Xiao-Long Wang, Min Fang, Yu Gao +5
Identifying the young optically visible population in a star-forming region is essential for fully understanding the star formation event. In this paper, We identify 211 candidate…
Gas dynamics and star formation in NGC 6822
Hye-Jin Park, Se-Heon Oh, Jing Wang +3
We present H I gas kinematics and star formation activities of NGC 6822, a dwarf galaxy located in the Local Group at a distance of ~ 490 kpc. We perform profile decomposition of l…
The Size-Mass Relation of Post-Starburst Galaxies in the Local Universe

We present a study of the size--mass relation for local post-starburst (PSB) galaxies at selected from the Sloan Digital Sky Survey Data Release 8. We find that PSB…
Spatially resolved mass-metallicity relation at z~0.26 from the MUSE-Wide Survey
Yao Yao, Guangwen Chen, Haiyang Liu +5
Aims: There is a spatially resolved star-forming main sequence (rSFMS) and mass-metallicity relation (rMZR) of galaxies in local universe. We know that the global mass-metallicity…
Sub-galactic scaling relations with T-based metallicity of low metallicity regions in galaxies: metal-poor gas inflow may have important effects?
