Scott Ransom Astronomer

Scott Ransom works on a wide variety of projects that involve finding, timing, and exploiting pulsars of various types, using data from many different instruments and at energies from radio waves to gamma-rays. His main focus is searching for exotic pulsar systems, such as millisecond pulsars and binaries. Once these pulsars are identified, he uses them as tools to probe a variety of basic physics, including tests of General Relativity, the emission of gravitational waves (and hopefully soon their direct detection, as part of the NANOGrav collaboration), and the physics of matter at supra-nuclear densities. Much of his time is spent working on the state-of-the-art signal-processing instrumentation, high-performance computing and software that pulsar astronomy requires.
