Career Beginnings

Cohen joined Cornell University in 1954, focusing on solar radio astronomy and studying the polarization of solar bursts. His involvement with the Arecibo project in 1958 allowed him to research compact radio sources and the solar wind through interplanetary scintillations.

Contributions to Radio Astronomy

In 1965, Cohen co-founded the Very Long Baseline Interferometry (VLBI) program in the United States. His research demonstrated that compact radio sources were tiny and led to the discovery of superluminal motion in active galactic nuclei jets. This breakthrough was essential in developing the relativistic beam theory of radio jets.

In 1971, Cohen, in collaboration with the Jet Propulsion Laboratory, established a VLBI processing laboratory at Caltech. This lab evolved to a 16-station facility, becoming a leading center for VLBI processing and analysis.

Advancements and Innovations

Cohen’s work in 1989 included developing polarimeters for the Hale and Keck telescopes, which enabled studies of active galactic nuclei and magnetic white dwarfs. His support for the Very Long Baseline Array (VLBA) led to his involvement in the 15GHz VLBA survey, now known as the MOJAVE survey.
