The atmospheric extinction curve at Lenghu site
Jin-Sheng Qiu, Xiao-Hui Xu, Qing-Feng Zhu +11
In this study, we use a dedicated spectroscopic telescope to carry out low-resolution measurements of the optical atmospheric extinction curve at Lenghu astronomical site in Qingha…
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…
