Dr. Green's research is focused on the design, development and use of space instrumentation for astrophysical studies, particularly ultraviolet astronomy. He was the Principal Investigator for the Cosmic Origins Spectrograph on the Hubble Space Telescope, designed and built the spectrograph for the Far Ultraviolet Spectroscopic Explorer, and has been a PI or Co-I on a sounding rocket program for 23 of the last 26 years. His observational focus is on the intergalactic medium, the galactic/IGM interconnection, and the interstellar medium. His theoretical focus is on studies of the very early universe.

ASTR 1200 - Stars and Galaxies
Non-science majors are introduced to the nature and workings of the Sun, stars, neutron stars, black holes, interstellar gas, galaxies, quasars, plus structure and origins of the universe. Some lectures may be held at Fiske Planetarium. Offers opportunities to attend nighttime observation sessions at Sommers-Bausch Observatory. Same as ASTR 1020 and ASTR 1040.
ASTR 2020 - Space Astronomy and Exploration
Covers physical principles of performing astronomy from space for science and exploration. The basic design of launch vehicles and spacecraft, orbital dynamics, and instruments will be described in the context of specific space missions (e.g. Hubble Telescope, Mars rovers) as well as prospects for future space observatories in orbit and on the Moon.
ASTR 5760 - Astrophysical Instrumentation
Spring 2019 / Spring 2021
Covers the fundamentals underlying the design, construction and use of instrumentation used for astrophysical research ranging from radio-wavelengths to gamma rays. Topics include Fourier transforms and their applications, optical design concepts, incoherent and coherent signal detection, electronics and applications, and signal acquisition and processing. Department enforced prerequisite: senior level undergraduate physics.
ASTR 6000 - Seminar in Astrophysics
Studies current research and research literature on an astrophysical topic. Students and faculty give presentations. Subjects vary each semester. May be repeated for a total of 4 credit hours to meet candidacy requirements.
