James M. Cordes
George Feldstein Professor of Astronomy
James Cordes's research interests include radio astronomy, neutron stars, pulsars, the interstellar medium, the search for extraterrestrial intelligence, signal processing techniques, statistical inference, and topics in computer science. He regularly makes observations using radio telescopes in Arecibo, Puerto Rico, the Very Large Array in New Mexico, the Parkes telescope in Australia, and the Very Long Baseline Array, headquartered in New Mexico. Cordes also makes infrared and optical observations using the Hale Telescope at Palomar and has taken part in joint radio and gamma-ray observations using the Compton Gamma-ray Observatory and X-ray Timing Explorer. He also uses the Hubble Space Telescope and the Chandra X-ray Satellite in his multiwavelength work. He is currently planning observations using the upgraded Arecibo Observatory and a new multiple-feed receiver system that involve deep searches for radio pulsars. He is also heavily involved in the Square Kilometer Array project, a next-generation radio telescope.
