The Narrow-Line Seyfert 1 Phenomenon: Accretion State Versus Host Galaxy Properties
Kaizheng Guo, Hassen M. Yesuf, Lei Hao +3
The physical origin of the narrow-line Seyfert 1 (NLS1) and broad-line Seyfert 1 (BLS1) dichotomy remains debated, with competing scenarios invoking host-galaxy evolution or intrin…
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…
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…
