Catching the Fastest Particles in the Universe | Miguel Mostafá | TEDxPSU 2016

What are the most energetic particles in the Universe? Where are they coming from? And more importantly, who cares?

Miguel Mostafa is an Associate Professor of Physics, and Astronomy and Astrophysics at Penn State University. He has been working on ultra-high energy cosmic rays as a member of the Pierre Auger Collaboration since 2001, and on very-high energy gamma rays as a member of the High Altitude Water Cherenkov Collaboration since 2009.

Radio Cosmic

The Auger Observatory is a "hybrid detector", employing two independent methods to detect and study high-energy cosmic rays. One technique detects high energy particles through their interaction with water placed in surface detector tanks. The other technique tracks the development of air showers by observing ultraviolet light emitted high in the Earth's atmosphere. The hybrid nature of the Pierre Auger Observatory provides for two independent ways to see cosmic rays.

To Los Leones - a 20-min ride in a 2-min video

12.5 km of gravel roads in the pampa in a 2-min video! Los Leones is the closest Fluorescence Detector building to Malargue.

This video is part of a travel diary called Journey to Auger, which relates the celebrations of AugerPrime in Malargüe, Argentina in Nov. 2015. The idea of this blog was to create a collection of new material about the Pierre Auger Observatory that mixes painting, drawing, photo, graphic design and video.

Pierre Auger Observatory Time Lapse

The Pierre Auger Observatory is the largest cosmic ray detector in the world. It covers an area of 3000 square kilometers with approximately 1600 surface detector stations which detect cosmic ray shower particles directly, as well as four fluorescence detectors which overlook the atmosphere above the surface array and detect fluorescence light emitted by shower particles. This time lapse sequence is constructed from a series of images captured in November-December 2013.

How cosmic rays help us understand the universe

We only know 4% of what the universe is made up of. Can we also know what lies beyond our galaxy ... and if there are undiscovered forms of matter? Luckily, we have space messengers — cosmic rays — that bring us physical data from parts of the cosmos beyond our reach. Veronica Bindi explains what cosmic rays are, and how they transmit information about our universe from the great beyond.

AERA Phase II, installing campaign in Malargue 2013

In this video we present the installation of the AERA Phase II with the addition of 100 radio stations in the argentinian pampas at the Pierre Auger Observatory.
