TL;DR
This study analyzes a large SDSS galaxy sample to explore how activity, morphology, and environment interrelate, using spectral classification and environmental catalogs.
Contribution
It introduces a comprehensive analysis combining spectral activity, environmental context, and morphological parameters for a large galaxy sample.
Findings
Correlation between galaxy activity and environment
Morphological parameters linked to activity levels
Environmental effects influence galaxy spectral properties
Abstract
We apply a stellar population synthesis code to the spectra of a large sample of SDSS galaxies to classify these according to their activity (using emission-line diagnostic diagrams), environment (using catalogues of isolated and cluster galaxies), and using parameters that correlate with their morphology.
