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…
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…
