Beyond Mass and Multiscale Environments: What Shapes Low Surface Brightness Galaxies? Evidence from MaNGA
Mengting Shen, Hassen M. Yesuf, Lei Hao +4
The origin of low surface brightness (LSB) galaxies remains a key open question in galaxy formation, reflecting the balance internal mechanisms and environmental influence. Using M…
SDSS-IV MaNGA: Distinct Structural Growth and Star Formation in Low and High Surface Brightness Disks
Mengting Shen, Jun Yin, Hassen M. Yesuf +7
We analyze a clean sample of 1,118 late-type, face-on galaxies without AGN contamination from the MaNGA survey. Their photometric structures are quantified via two-component (bulge…
Mock Observations for the CSST Mission: Integral Field Spectrograph--GEHONG: A Package for Generating Ideal Datacubes
Shuai Feng, Shiyin Shen, Wei Chen +17
We developed a Python package GEHONG to mock the three-dimensional spectral data cube under the observation of an ideal telescope for the Integral Field Spectrograph of the Chinese…
Non-Parametric Attenuation Curves in Local Star-Forming Galaxies: Geometry Effect, Dust Evolution, and ISS
Jiafeng Lu, Xi Kang, Shiyin Shen +2
We introduce a non-parametric approach, the Stellar Population Synthesis with Equivalent Widths (SEW) method, to reconstruct spectrally-resolved attenuation curves for 169,568 star…
Mock Observations for the CSST Mission: Integral Field Spectrograph--Instrument Simulation
Zhao-Jun Yan, Jun Yin, Lei Hao +25
The Chinese Space Station Survey Telescope (CSST) is a next-generation Stage-IV facility renowned for its wide field of view, high image quality, and multi-band observational capab…
The Velocity Map Asymmetry of Ionized Gas in MaNGA II. Correlation between Velocity Map Morphology, Star Formation, and Metallicity in Regular Disk Galaxies
Shuai Feng, Shiyin Shen, Yanmei Chen +5
The morphology of ionized gas velocity maps provides a direct probe of the internal gas kinematics of galaxies. Using integral field spectroscopy from SDSS-IV MaNGA, we analyze a s…
