Reuven Ramaty

1969-2001 Astrophysicist, Laboratory for High Energy Astrophysics (government employed) 1980-1993 Head of Theory Office, Laboratory for High Energy Astrophysics (government employed) 1974-1977 Associate Editor for Physical Review Letters 1977-1978 Chairman of The American Physical Society, Astrophysics division 1984-1985 Chairman of The American Physical Society, High Energy Astronomy Division NASA Exceptional Scientific Achievement Award 1980 Reuven Ramaty (1937—2001) was a Hungarian astrophysicist who worked for 30 years at NASA's NASA Goddard Space Flight Centre.

Ramaty remained in Israel for 16 years, where he finished his secondary education and graduated from Tel Aviv University in 1961 with a Bachelor of Science in physics.

During his career, Ramaty remained active in tertiary education institutions as he was an adjunct professor of physics[3] at the University of Maryland from 1983, where he served as a PhD advisor for six students.

Ramaty was one of the leading scientists in the field of gamma-ray line astronomy and solar flare physics, cosmic rays and flare-accelerated particles.

With the help of Ramaty's work and his contributions to the field, the observation of Doppler broadening and shape details in nucleosynthesis events are now possible with the RHESSI solar imager and The Compton Observatory.

Recent observations within the NASA RHESSI project show his early calculations on low-energy cosmic ray lines and theories on solar flare emissions to be accurate and consistent.

Following the initial discoveries of these observations, Ramaty spent 30 years refining his findings with the Solar Maximum Mission along with the Compton Gamma Ray Observatory.

More of this work, with detailed analysis and presentations of his findings, can be found in the article "Gamma Ray Lines: A New Window to the Universe", co-authored by Ramaty.

Ramaty had a long and distinguished career in the Laboratory for High-Energy Astrophysics developing much of the theoretical framework for solar gamma-ray line spectroscopy.

[13] Using this work, Ramaty continued to pursue his studies in low energy cosmic rays and has published multiple papers on the subject, five of which are available on The Online Archive of California.

[12] His early work in the field has been credited by Richard Lingenfelter, Neil Gehris and Thomas L. Cline as essential for the current discoveries being made through the RHESSI project.

This work in solar flare emissions is reflected in his later papers from 1973 to 1989, which allowed for closer observations to be made following the launch of the RHESSI project in 2002.
