_______________________________________________Dear all,
This week we have the pleasure of hosting Dr. Roberta Colalillo from the University of Naples. Dr. Colalillo will discuss her research work on atmospheric studies at the Pierre Auger Observatory.The seminar will take place in the J. Sacton Room this Friday, May 8th, at 2:00 PM.
Please find further details below:

Title: Results and prospects in atmospheric electricity studies at the Pierre Auger Observatory
Abstract: The Pierre Auger Observatory, beyond its primary focus on cosmic rays, also yields valuable results in cosmogeophysics. Over the past decade, its fluorescence detector (FD) has captured ELVES, light emissions from the upper mesosphere caused by lightning. Exploiting high time resolution, we validated model predictions on double and triple ELVES. Moreover, the FD traces hinted at observing other transient luminous events (TLEs), such as halos, promoting the installation of a dedicated camera in December 2023 to detect their optical counterparts. It has registered several SPRITES and the first ELVES. The surface detector captures Cherenkov signals from TGFs, complementing FD with near-field cosmogeophysics data. The time resolution of the order of tens of ns and the possibility to sample the whole TGF footprint unlike in the other experiments designed for TGF detection allows us to constrain production mechanisms.

I am looking forward to a well-attended seminar and to seeing many of you on Friday!
Best,Simona.
