ELFO: A Python Package for Emission Line Fitting Optimization in Integral Field Spectroscopy Data
Hui Guo, Guilin Liu, Jianghui Xu +4
Integral field spectroscopy (IFS) provides spatially resolved spectra, enabling detailed studies that address the physical and kinematic properties of the interstellar medium. A cr…
The origin of double-peaked narrow emission-line galaxies in MaNGA Survey
Zhiyun Zhang, Yanmei Chen, Shiyin Shen +5
We select 36 double-peaked narrow emission-line galaxies (DPGs) from 10,010 unique galaxies in MaNGA survey. These DPGs show double-peaked Balmer lines and forbidden lines in the s…
SEW: A full-spectrum linear fitting with stellar population synthesis method Based on "Equivalent Widths spectrum"
Jiafeng Lu, Xi Kang, Shiyin Shen
We present a full-spectrum linear fitting method, SEW, for stellar population synthesis based on equivalent widths (EWs) to extract galaxy properties from observed spectra. This ap…
Radial Profiles of , , Gas Metallicity and Their Correlations Across the Galactic Mass-Size Plane
Lin Lin, Shiyin Shen, Hassen M. Yesuf +2
We analyzed the global and resolved properties of approximately 1,240 nearby star-forming galaxies from the MaNGA survey, comparing compact and extended galaxies -- those with smal…
