UV and NIR size of the HI selected low surface brightness galaxies
Cheng Cheng, Wei Du, Cong Kevin Xu +10
How does the low surface brightness galaxies (LSBGs) form stars and assemble the stellar mass is one of the most important questions to understand the LSBG population. We select a…

A clear link between a dwarf-dwarf merger event and enhanced star formation (SF) in the recent past was recently identified in the gas-dominated merger remnant VCC 848, offering by…
Lessons on Star-forming Ultra-diffuse Galaxies from The Stacked Spectra of Sloan Digital Sky Survey
Yu Rong, Kai Zhu, Evelyn J. Johnston +4
We investigate the on-average properties for 28 star-forming ultra-diffuse galaxies (UDGs) located in low-density environments, by stacking their spectra from the Sloan Digital Sky…
New Constraints on the Origin of Surface Brightness Profile Breaks of Disk Galaxies from MaNGA
Yimeng Tang, Qianhui Chen, Hong-Xin Zhang +6
In an effort to probe the origin of surface brightness profile (SBP) breaks widely observed in nearby disk galaxies, we carry out a comparative study of stellar population profiles…
The Most Predictive Physical Properties for the Stellar Population Radial Profiles of Nearby Galaxies
Guangwen Chen, Hong-Xin Zhang, Xu Kong +5
We present a study on the radial profiles of D4000,luminosity-weighted stellar ages ,and luminosity-weighted stellar metallicities of 3654 nearby galaxies($0.01<z<0.…
The Next Generation Fornax Survey (NGFS): VII. A MUSE view of the nuclear star clusters in Fornax dwarf galaxies
Evelyn J. Johnston, Thomas H. Puzia, Giuseppe D'Ago +16
Clues to the formation and evolution of Nuclear Star Clusters (NSCs) lie in their stellar populations. However, these structures are often very faint compared to their host galaxy,…
The Blue Compact Dwarf Galaxy VCC848 Formed by Dwarf-Dwarf Merging
Hong-Xin Zhang, Sanjaya Paudel, Rory Smith +8
It has long been speculated that many starburst or compact dwarf galaxies are resulted from dwarf-dwarf galaxy merging, but unequivocal evidence for this possibility has rarely bee…
The Next Generation Virgo Cluster Survey. XVII. A Search for Planetary Nebulae in Virgo Cluster Globular Clusters
Weijia Sun, Eric W. Peng, Youkyung Ko +11
The occurrence of planetary nebulae (PNe) in globular clusters (GCs) provides an excellent chance to study low-mass stellar evolution in a special (low-metallicity, high stellar de…
Intrinsic Morphology of Ultra-diffuse Galaxies
Yu Rong, Xiao-Yu Dong, Thomas H. Puzia +10
With the published data of apparent axis ratios for 1109 ultra-diffuse galaxies (UDGs) located in 17 low-redshift (z~ 0.020 - 0.063) galaxy clusters and 84 UDGs in 2 intermediate-r…
A Collection of New Dwarf Galaxies in NGC5128's Western Halo
Matthew A. Taylor, Paul Eigenthaler, Thomas H. Puzia +5
We report the photometric properties of 16 dwarf galaxies, 15 of which are newly identified, in the Western halo of the nearby giant elliptical galaxy NGC5128. All candidates are f…
The Next Generation Virgo Cluster Survey (NGVS) XXXI. The kinematics of intra-cluster globular clusters in the core of the Virgo cluster
Alessia Longobardi, Eric W. Peng, Patrick Côté +21
Intra-cluster (IC) populations are expected to be a natural result of the hierarchical assembly of clusters, yet their low space densities make them difficult to detect and study.…
The Dawn Light of Blueberry Galaxies: Spectroscopic and Photometric Studies of two Starburst Dwarf Galaxies
Yu Rong, Huan Yang, Hong-xin Zhang +8
A population of so-called "blueberry" starbursting dwarf galaxies with extremely blue colors, low-metallicities, and enormous ionization ratios, has recently been found by Yang et…
