Title of thesis:
Searching for ultra high energy photons using data from the Pierre Auger Observatory
Cosmic rays are charged particles from our galaxy and the wider universe with a vast range of energies. The highest energy cosmic ray observed so far is ~100 million million million times the energy of photons emitted from a light bulb and still ~10 million times the energy of particles accelerated in the Large Hadron Collider LHC. To understand how nature created such extreme energy particles, experiments carried out by balloons, satellites and ground based detectors have been built in the past. The Pierre Auger Observatory in Argentina is the biggest such experiment ever, and it is set for the highest energy cosmic rays. It covers an area of 3000 km2, about 30 times of the area of Paris, to record as many of these mystery particles as possible, and to unravel their origin and the mechanisms by which they get to these gigantic energies. Through my PhD, I am trying to find photons with ultra high energies using data from the Pierre Auger Observatory. No such observations have been claimed so far although the existence of these photons has been predicted from various theories such as the super heavy dark matter model.
