Ground-based Gamma-Ray Astronomy: an Introduction
Journal of Physics: Conference Series, 2019 Abstract During the last two decades Gamma-Ray Astronomy has emerged as a powerful tool to study cosmic ray physics. In fact, photons are not deviated by galactic or extragalactic magnetic fields so their directions bring the information of the production sites and are easier to detect than neutrinos.

The Striated Solar Photosphere Observed at Resolution
The Astrophysical Journal LettersStriated granular edges observed in the solar photosphere represent one of the smallest-scale phenomena on the Sun. They arise from the interaction of strongly coupled hydrodynamic, magnetic, and radiative properties of the plasma.

Spatiotemporal Variations of Temperature in Jupiter’s Upper Atmosphere
The Planetary Science JournalGlobal temperatures in Jupiter’s upper atmosphere are poorly constrained. Other than an in situ measurement by the Galileo Probe, all temperature data come from remote-sensing methods that primarily rely on emissions from H ${}_{3}^{+}$ , the dominant ...
