Marvin: A Toolkit for Streamlined Access and Visualization of the SDSS-IV MaNGA Data Set
MaNGA (Mapping Nearby Galaxies at APO) is one of the three main surveys of the SDSS-IV program. MaNGA will provide integral field spectroscopy of an unprecedented sample of nearly 10,000 galaxies. As part of SDSS, MaNGA data is being made public in annual data releases; DR15 is the third and most recent release of MaNGA data (and the first which includes maps of derived properties). DR15 also includes the release of Marvin to the public. Marvin is a new tool designed for streamlined access to the MaNGA data, optimized for overcoming the challenges of searching, accessing, and visualizing the complexity of the MaNGA dataset. At its core, Marvin provides user-unaware local/remote data access eliminating logistical overheads and delivering exactly the content you want, when you want it. Marvin has two main components: a Web Interface, for a quick visual introduction into the world of MaNGA data, and a Python package of tools, for more in-depth scientific analysis and inclusion in your science workflow. This demo serves as an introduction to Marvin for the astronomy community by members of the Marvin Team. The demo will showcase using the web interface including how to visually navigate, search for, and inspect MaNGA galaxies; and using Python including how to quickly access data files, query the dataset, and deep-dive into more detailed analysis. The aim of the demo will be to provide users familiarity with the Marvin tool suite to begin exploring the MaNGA dataset for their science immediately.
