Galaxy photometric redshift (photo-) is crucial in cosmological studies, such as weak gravitational lensing and galaxy angular clustering measurements. In this work, we try to e…
Automatic detection of low surface brightness galaxies from SDSS images
Zhenping Yi, Jia Li, Wei Du +7

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…
Self-consistent Color-Mass-to-Light-Ratio relations for Low Surface Brightness Galaxies
Wei Du, Stacy S. McGaugh
The color - stellar mass-to-light ratio relation (CMLR) is a widely accepted tool to estimate the stellar mass (M*) of a galaxy. However, an individual CMLR tends to give distinct…

We report new HI observations of four z0.05 star-forming galaxies undertaken during the commissioning phase of the Five-hundred-meter Aperture Spherical Radio Telescope (FAST…
A Sample of Edge-on HI-rich low-surface-brightness Galaxy Candidates in the 40% ALFALFA Catalog
Min He, Hong Wu, Wei Du +4
Low-surface-brightness galaxies(LSBGs) are defined as galaxies that are fainter than dark night sky and are important for studying our universe. Particularly, edge-on galaxies are…
Stellar Mass and stellar Mass-to-light ratio-Color relations for Low Surface Brightness Galaxies
Du Wei, Cheng Cheng, Zheng Zheng +1
We estimate the stellar mass for a sample of low surface brightness galaxies (LSBGs) by fitting their multiband spectral energy distributions (SEDs) to the stellar population synth…
UV and NIR size of the low-mass field galaxies: the UV compact galaxies
Cheng Cheng, Cong Kevin Xu, Lizhi Xie +10
Most of the massive star-forming galaxies are found to have `inside-out' stellar mass growth modes, which means the inner parts of the galaxies mainly consist of the older stellar…
An accurate analytic mass model for lensing galaxies
Wei Du, Gong-Bo Zhao, Zuhui Fan +3
We develop an analytic mass model for lensing galaxies, based on a broken power-law (BPL) density profile, which is a power-law profile with a mass deficit or surplus in the centra…
Further evidence for a population of dark-matter-deficient dwarf galaxies
Qi Guo, Huijie Hu, Zheng Zheng +9
In the standard cosmological model, dark matter drives the structure formation and constructs potential wells within which galaxies may form. The baryon fraction in dark halos can…
