Abstract:Establishing a correlation (or lack thereof) between the bimodal colour distribution of galaxies and their structural parameters is crucial to understand the origin of bimodality. To achieve that, we have performed 2D mass-based structural decomposition (bulge+disc) of all disc galaxies (total=1263) in the Herschel imaging area of the Stripe 82 region using K s band images from the VICS82 survey. The scaling relations thus derived are found to reflect the internal kinematics and are employed in combination to … Show more
