A Strong Stellar Age-Metallicity Gradient Relation in Nearby Dwarf Galaxies Driven by Stellar Migration and Environmental Quenching
Tie Li, Hong-Xin Zhang, Wenhe Lyu +16
Stellar metallicity gradients () provide a fossil record of the assembly history of galaxies. We present an analysis of for 90 nearby low-mass galaxies u…
The First Systematic Survey of Stellar Halos in High-Inclination Galaxies Reveals Unusually Quiescent Merger Histories of Nearby Galaxies
Bojun Tao, Hong-Xin Zhang, Wenting Wang +8
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…
AVID: Formation and evolution of a coalesced major merger of late-type dwarf galaxies (VCC 479) on the outskirts of the Virgo cluster
Weibin Sun, Hong-Xin Zhang, Rory Smith +24
Dwarf-dwarf galaxy mergers are among the least explored aspects of dwarf galaxy pre-processing as they fall into clusters. We present the first case study of a coalesced late-type…
Ly imaging around the hyperluminous dust-obscured quasar W22460526 at
Yibin Luo, Lulu Fan, Yongming Liang +10
Hot dust-obscured galaxies (Hot DOGs) are a population of hyperluminous, heavily obscured quasars discovered by the \emph{Wide-field Infrared Survey Explorer} (\emph{WISE}) all-sky…
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…
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…
An overdensity of red galaxies around the hyperluminous dust-obscured quasar W18354355 at
Yibin Luo, Lulu Fan, Hu Zou +6
\emph{Wide-field Infrared Survey Explorer} all-sky survey has discovered a new population of hot dust-obscured galaxies (Hot DOGs), which has been confirmed to be dusty quasars. Pr…
