Comparison of [CII] 158µm line widths to luminosities

Abstract

Acomparison of [CII] 158µm emission line widths to different luminosities is presented to decide if any luminosity relates to velocity dispersion. [CII] 158 µm emission lines are observed with Herschel PACS for 379 galaxies and the archival data for [CII] line widths are taken from http://cassis.sirtf.com/ herschel/. Emission line widths are compared to [CII] luminosities, to near-infrared 1.6µm luminosities and to infrared 22µm luminosities. H magnitudes are taken from 2MASS catalogue, and 22µm fluxes from the WISE catalogue.
