DESCRIPTION:Speaker: Melissa Pesce-Rollins (Istituto Nazionale di Fisica N
 ucleare | Pisa\, Italy)\nTitle: The flaring gamma-ray Sun: 17 years of obs
 ervations with the Fermi Large Area Telescope\nAbstract: The Fermi Large A
 rea Telescope (LAT) observations of the active Sun provide the largest sam
 ple of detected solar flares with emission greater than 30 MeV to date. Th
 ese include detections of impulsive and hours-long sustained emission as w
 ell as greater than 100 MeV emission from flares whose active regions wher
 e located behind the visible limb. Identifying the mechanism responsible f
 or accelerating electrons/ions and the site at which it occurs is one of t
 he outstanding questions in solar physics. Many advances have been made ov
 er the past decade thanks to new observational data and refined simulation
 s that together help to shed light on this topic. In this seminar I will p
 rovide a brief overview of the most salient results from the first 17 year
 s of Fermi-LAT in orbit and how this observational channel combined with o
 bservations from across the electromagnetic spectrum can provide a unique 
 opportunity to diagnose the mechanisms of high-energy emission and particl
 e acceleration in solar flares.\nNote: Host: Jake Mitchell\n
