CSE Speaker Series – Urvashi Rau

On Friday, April 20 at 11:00 am in Cramer 221, Dr. Urvashi Rau of NRAO will give a talk on “Computing and Algorithms in Radio Interferometry”.

Abstract :   The National Radio Astronomy Observatory (NRAO) operates two imaging radio interferometers, the Very Large Array (VLA) in New Mexico and the Atacama Large Millimeter Array (ALMA) in Chile. Our teams do algorithm research as well as software design/development for observation preparation, data analysis tools, automated end-to-end data processing frameworks and archive management.  We are currently working towards complete automation of our existing algorithms and data processing chains, planning for a compute-heavy upgrade to ALMA in the next few years and working on the conceptual design of a new telescope in and around New Mexico that (if funded) would be about two orders of magnitude larger than the VLA.  In this talk I would like to introduce what we do, how each step of our data analysis and image reconstruction process connects to specific topics in computer science, and what our current and future algorithmic and computing challenges are.  Some of these topics may be appropriate for future collaborative R&D work between the NRAO and NMT.
