Speaker
Description
The talk will begin with an overview of the National Radio Astronomy Observatory (NRAO), a facility of the National Science Foundation (NSF) tasked with building and operating radio telescopes and instrumentation for the global astrophysics community. I will briefly describe the four world-class instruments we currently operate, along with forthcoming key instrumentation upgrades and the Next Generation Very Large Array (ngVLA) currently under development. This will be followed by an introduction to the principles of astronomical interferometry and a discussion of the key electronic components and enabling technologies that go into a modern radio telescope. I will conclude with a technical focus on a key component of my own research---the reflectionless filter---which was developed initially to meet the needs of radio astronomy but which has proven beneficial in wide variety of applications including wireless communications, test and measurement instrumentation, defense, and most recently in quantum computing.
