From relics to stripped systems: the environmental origin of compact galaxies
Guangwen Chen, J. Alfonso L. Aguerri, Carlos del Burgo +1
Compact galaxies represent a key population for understanding galaxy evolution, but the relative role of internal structure and environment in shaping their origin remains unclear.…
A Strong Stellar Age-Metallicity Gradient Relation in Nearby Dwarf Galaxies Driven by Stellar Migration and Environmental Quenching

Stellar halos are the only major stellar component of disk galaxies that lack systematic observational characterization, yet they encode critical information about galaxy merger hi…
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…
Galaxy mass dependence of metal-enrichment of nuclear star clusters
Wenhe Lyu, Hong-Xin Zhang, Sanjaya Paudel +5
Nuclear Star Clusters (NSCs) are commonly found in galaxy centers, but their dominant formation mechanisms remain elusive. We perform a consistent analysis of stellar populations o…
Radio-to-Submillimetre Spectral Energy Distributions of NGC 1365

Weibin Sun, Lulu Fan, Yunkun Han +3
We present a UV to millimeter spectral energy distribution (SED) analysis of 16 hyperluminous, dust-obscured quasars at z 3, selected by the \textit{Wide-field Infrared Surv…
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…
Star formation in the centre of NGC 1808 as observed by ALMA
Guangwen Chen, George J. Bendo, Gary A. Fuller +2
We present Atacama Large Millimeter/submillimeter Array (ALMA) observations of 85.69 and 99.02 GHz continuum emission and H42 and H40 lines emission from the central 1~kpc of…
Dynamical hotness, star formation quenching and growth of supermassive black holes
Hui Hong, Huiyuan Wang, H. J. Mo +8
A stellar system is dynamically hot when its kinetic energy is dominated by random motion represented by the velocity dispersion . We use MaNGA data to obtain in…
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…
