AVID: A Near-Major Post-Merger of Late-Type Dwarfs beneath a Regularly Rotating HI Disk (VCC 693)
Fujia Li, Hong-Xin Zhang, Elias Brinks +23
On the periphery of galaxy clusters, moderately high galaxy densities and velocity dispersions favour interactions and mergers that influence galaxy evolution prior to cluster infa…
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…
Unveiling the nature and fate of the almost-dark cloud AGC 226178 through HI mapping
Yu-Zhu Sun, Hong-Xin Zhang, Elias Brinks +18
The origin of extragalactic, almost dark HI clouds with extreme gas-to-stellar mass ratios remains poorly understood. We investigate the nature and fate of the "almost dark" cloud…
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…
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…
