Demographics of Galaxies in the Nearby Universe: A case study with AGN and post-mergers

<p>Here I present a volume limited catalog of ~113,600 visually classified galaxies from SDSS and the NOAO legacy survey. The classifications include identifications of bars, rings, spiral arms, tidal tails, etc.&nbsp; I compare my classifications to those from other crowd sourced surveys and machine learning based catalogs to verify classification accuracy.&nbsp; Using this catalog, I will show results on the systematics which affect quantitative/ML classifications and implications for the Nancy Grace Roman space telescope galaxy surveys. Time permitting I will discuss (a) bar fractions in the local Universe and role of close pair interactions in triggering bars&nbsp; (b) the role of mergers in triggering AGN and the frequency of dual AGN in the local Universe.</p>
