abstract
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-by-event statistical method, we derive upper limits on the absolute flux of primary photons with energies above 10^19, 10^19.5 and 10^20 eV based on the first three years of data taken.

Analysing Ultra High Energy Cosmic Rays' Anisotropy in $\boldsymbol{f(R, T)}$ Gravity Theory
Under f(R,T) gravity models, the predicted dipole anisotropy of diffusive UHECRs is lower than under ΛCDM, and with tuned magnetic field and source distance both fit Pierre Auger data.
