Upper limit on the flux of photons with energies above 10^19 eV using the Telescope Array surface detector

T. Abu-Zayyad, R. Aida, M. Allen +138

We search for ultra-high energy photons by analyzing geometrical properties of shower fronts of events registered by the Telescope Array surface detector. By making use of an event…

New air fluorescence detectors employed in the Telescope Array experiment

H. Tokuno, Y. Tameda, M. Takeda +134

Since 2007, the Telescope Array (TA) experiment, based in Utah, USA, has been observing ultra high energy cosmic rays to understand their origins. The experiment involves a surface…
