California Institute of Technology, Stanford University, University of California Berkeley, University of California San Diego, University of Pennsylvania and Washington University in St. Louis. Notable work Ramaty was a postdoctoral research associate (Laboratory for High Energy Astrophysics), Astrophysicist (Laboratory for High Energy Astrophysics), Head of Theory Office (Laboratory for High Energy Astrophysics), Associate Editor for Physical Review Letters, chairman of the American Physical Society (Astrophysics division), Chairman of the American Physical Society (High Energy Astronomy Division) and, Divisional councillor for astrophysics for the American Physical Society (APS). His most notable work was carried out at the NASA Goddard Space Flight Center, where he worked for over 30 years. Ramaty was one of the leading scientists in the field of gamma-ray line astronomy as well as devoting his studies to solar flare physics, cosmic rays and flare-accelerated particles. His work has contributed a wealth of information to the literature in the astrophysical field with over 200 published works under his name and with over 5,000 citations to his works as of 2001, Ramaty is credited with the invention of studies regarding the observation of high-energy nuclear reactions in solar flares, as well as the use of gamma-ray line observations of flare-accelerated particles to determine their specific properties. The use of gamma-ray line astronomy at the time was new to the field as it had not been a tool to observe low-energy cosmic rays in interstellar space. With the help of Ramaty's work and his contributions to the field, the observation of Doppler broadenings and shape details from nucleosynthesis events are now possible with the RHESSI solar imager and The Compton Observatory. In addition to this, his work on flare accelerated particles from solar energetic particle events built the foundation for the magnetohydrodynamic simulations which are being used to resolves new paradoxes regarding these particles. Having used these simulations. Ramaty's findings have compared favourably with the observations being made today. With the NASA RHESSI project's observations, Ramaty's early calculations on low-energy cosmic ray lines and theories on solar flare emissions are now being tested, showing his work 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. This effort was carried out mainly with the help of Benz Kozlosvsky from Ramaty's alma mater, Tel Aviv University. These discoveries would then lead
