TL;DR
This study analyzes a large sample of low surface brightness galaxies from SDSS, examining their properties and comparing them with higher surface brightness galaxies to understand their characteristics and variations.
Contribution
It provides a comprehensive analysis of LSB galaxy properties and their differences from higher surface brightness galaxies using multiwavelength data.
Findings
LSB galaxies have distinct magnitudes, colors, and stellar populations.
Surface brightness correlates with metallicity and stellar mass.
LSB galaxies show unique spectral energy distributions across wavelengths.
Abstract
A large sample of low surface brightness (LSB) disk galaxies is selected from SDSS with B-band central surface brightness mu_0(B) from 22 to 24.5 mag arcsec^(-2). Some of their properties are studied, such as magnitudes, surface brightness, scalelengths, colors, metallicities, stellar populations, stellar masses and multiwavelength SEDs from UV to IR etc. These properties of LSB galaxies have been compared with those of the galaxies with higher surface brightnesses. Then we check the variations of these properties following surface brightness.
