About

CM4Seyferts (Color-Magnitude for Seyferts): Using ultraviolet images from the Galaxy Evolution Explorer (GALEX) satellite and optical images and spectra from the ground based Sloan Digital Sky Survey (SDSS) to find a correlation between the color and luminosity of the hot gas around supermassive black holes at the centers of galaxies.


Abstract

Data from the Sloan Digital Sky Survey (SDSS) and the Galaxy Evolution Explorer (GALEX) satellite will be used to extend the work of the 2010 and 2012 NITARP teams in demonstrating a hypothesized correlation between the luminosity and color (temperature) of the accretion disk within Type I Active Galactic Nuclei (AGN). The 2012 NITARP team was successful in finding a trend in the UV luminosity and color of the AGN in Type I quasars, however the sample size was not sufficient in demonstrating a substantial correlation. More data are needed to see if a more substantial correlation exists; therefore, data from less luminous AGN must be used. Our project will attempt to investigate whether a more significant trend is revealed when Type I Seyfert galaxies with redshifts 0.1 < z < 0.5 are added to the 2012 team's quasar sample.
