Abstract: E01.00019 : Interactively Investigating the Extragalactic Sky*
of exploring the data efficiently and effectively to help answer specific
research questions. The DESI Legacy Imaging Surveys are delivering optical and
mid-infrared imaging of 14,000 square degrees of the extragalactic sky, and in
the latest (eighth) public data release delivered hundreds of measurements for
well over one billion stars and galaxies (http://legacysurvey.org).
To facilitate exploratory data analysis of this massive dataset, we present two
dedicated web applications built using a Python/Django web framework. The first
application provides interactive data access to a sample of more than 20,000
cluster central galaxies, which rank among the most massive galaxies in the
universe, and the second application is a fast, web-based viewer which allows
scientists (and the public) to explore the extragalactic sky at a wide range of
wavelengths and angular scales.
