One Degree Imager - Developing an Astronomy Science Gateway and Archive



We are all fascinated with the night sky and the glimpse it provides into the structure of the universe. Scientists in the WIYN consortium are constructing what will be the most powerful earth-based light telescope in existence for many years to come. The One Degree Imager (ODI) is unique, high resolution camera to be installed at the Kitt Peak Observatory near Tucson, Arizona. The ODI will cover a one-square-degree field of view, which will allow it to capture in a single image an area greater than four times the area of the full moon. Because this device will be able to see smaller objects than any other earth-based telescope, it will also create much more data per night than earlier telescopes. The size of ODI data will be too large for conventional data management and computation on desktop computers. XSEDE and IU are engaged in a multiyear effort to plan a data management and analysis system to speed images from the telescope to the computers of scientists and the lay public as quickly as possible. The NSF-funded Open Gateway Computing Environments (OGCE) project and developers from the Data to Insight (D2I) Center, part of the Indiana University Pervasive Technology Institute, are working with NOAO instrument and pipeline scientists to develop a Web based science gateway that will use the NSF XSEDE supercomputing infrastructure (Ranger, Lonestar, Trestles) as well as Indiana University storage resources to support the data processing workflows and remote data access required by ODI.

When completed, ODI will be the only instrument of its kind that is available to the entire astronomical community. Furthermore, it will be considered a “general facility” instrument, which means that it has been designed to support many different types of scientific programs, rather than one specific type of program or survey, as many of the larger- format cameras built or being built. Unlike the prevailing large survey efforts, ODI will provide high resolution scientific imagery that is guided by the scientific investigations of small astronomy teams. XSEDE provides both the access to the nation’s top academic computing facilities and the support and expertise of the community-leading Science Gateway program.
