Jorge Fernando Valle Silva

I'm a Research Scientist in Solar Physics at the National Institute for Space Research (INPE) currently working on instrumentation and software development for radio projects. I previously did research at Mackenzie Presbyterian University working with Dr. C.G. Giménez de Castro and Dr. Jean-Pierre Raulin on submillimeter observations of the Sun. My research work focuses on studying solar flares and active regions using observations at submillimeter wavelengths.

My research interests include investigating the thermal components of solar flares, atmospheric opacity measurements for ground-based solar observations, and the relationship between submillimeter radiation and solar activity cycles. I've made contributions to understanding the role of submillimeter radiation as part of the Neupert Effect in solar flares and characterized active region brightness temperature variations over solar cycles 23 and 24.

I work extensively with data from the Solar Submillimeter Telescope (SST) at frequencies of 212 and 405 GHz, analyzing both quiet Sun and transient solar phenomena. My recent work has focused on establishing correlations between submillimeter observations and other solar activity indicators, as well as studying major flare events like the September 2017 X9 super flare across multiple wavelengths.
