Marc Postman (born April 6, 1958) is an American astronomer at the Space Telescope Science Institute[1] in Baltimore, Maryland, United States.
His recent research includes characterizing the properties of brightest cluster galaxies [2] [3] [4] [5] and placing new constraints on the cosmic optical background.
He served on the science and technology definition team for the Large Ultraviolet Optical Infrared Surveyor concept (aka LUVOIR), which was proposed to the 2020 Astronomy and Astrophysics Decadal Survey.
Postman is also a guest investigator on the New Horizons science team to study the ultraviolet and optical background radiation field as seen from the unique vantage point beyond 45 AU from the Sun.
