Defining Galaxy Environments Using the NASA/IPAC Extragalactic Database (NED)
Abstract
In its January 2013 release NED will provide users with quantitative environmental information for galaxies known to the database that have spectroscopic redshifts. A quick-look Environmental Vector will provide the hierarchical space density of radial-velocity-confirmed galaxies in predefined physical regions of space (shells) surrounding the selected galaxy. A tabular census of those galaxies making up the environment will be provided to the user for off-line analysis. A number of visualizations and diagnostic plots will be provided on the NED interface in real time.
