Widespread Inflows Reveal Baryonic Cycling in Star-forming and Quiescent Galaxies
Hassen M. Yesuf, Ravi Joshi, Yuxuan Zou +8
Cool-gas inflows, required to sustain star formation, have been fundamental in simulations yet remained observationally elusive. Using DESI spectroscopy of ~30,000 galaxies, we ide…
The Structural Abundance Crisis of Massive Galaxies in Current Cosmological Simulations
Hassen M. Yesuf, Connor Bottrell, Luis C. Ho +5
The internal structure of galaxies encodes the complex baryon cycle driven by gas accretion, star formation, and feedback, together with secular evolution and environmentally drive…
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--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…
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…
On the HI Content of MaNGA Major Merger Pairs
Qingzheng Yu, Taotao Fang, Shuai Feng +4
The role of HI content in galaxy interactions is still under debate. To study the HI content of galaxy pairs at different merging stages, we compile a sample of 66 major-merger gal…
Spatially resolved star formation and dust attenuation in Mrk848: Comparison of the integral field spectra and the UV-to-IR SED
F. -T. Yuan, M. Argudo-Fernandez, S. Shen +5
We investigate the star formation history and the dust attenuation in the galaxy merger Mrk848. Thanks to the multiwavelength photometry from the ultraviolet (UV) to the infrared (…
