Richard Schwartz
by Dennis, Brian R. (GSFC-6710) 31 Dec '20

31 Dec '20

Richard Schwartz died unexpectedly at his home on Saturday, 12 December. Although he had been sick for over a month, he was preparing to begin chemotherapy for Non-Hodgkin's lymphoma so his sudden passing was a great shock. Richard got a BS from Carnegie-Mellon University in 1974 and a PhD from the University of California, Berkeley, in 1984. After a couple of years at JPL, he came to Goddard and joined Ken Frost's X-ray group working on the solar flare data from the Hard X-ray Burst Spectrometer (HXRBS) on the Solar Maximum Mission (SMM). Since then he has been involved in the analysis of data from almost every space mission that has made high energy solar flare observations. His biggest role has been the scientist responsible for the RHESSI data analysis software. He was playing a similar role for the Spectrometer/Telescope for Imaging X-rays (STIX) on the Solar Orbiter. His main skill was the ability to combine scientific understanding with efficient computational techniques. Richard's problem solving capabilities, prodigious memory, insightful but often acerbic wit, and imposing presence will be sorely missed by his many friends at Goddard and around the world in the international high-energy solar physics community.

Two new RHESSI Nuggets
by Hugh Hudson 16 Dec '20

16 Dec '20

http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets No. 396, “Investigation of Small-Scale Energy Releases in Hard X-rays with FOXSI”, by Subramania ATHIRAY and Juliana VIEVERING: Hard X-rays and high temperatures in the feeblest microflares. No. 397, "Solar effects in the local interstellar medium”, by Don GURNETT and Hugh HUDSON: Relativistic particle events observed _in situ_ in the local interstellar medium. We welcome contributions to the RHESSI Nuggets, and the topics may wander some distance away from specifically RHESSI results if they are generally interesting. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for these and others. Comments about specific flares can often be found by searching for their SOLyyyy-mm-dd identifier from this home page.
