Line Flux Characterization of Galaxies in the Green Valley

In this work, we use spectroscopic and photometric data from the Sloan Digital Sky Survey to study the spectrophotometric properties of galaxies in the nearby universe. We introduce a new quantity, we call it the “Spectral Line Ratio Space” created by the ratio of flux of spectral lines in galaxies,...
