is a gamma ray a particle?
A gamma ray is a form of high energy electromagnetic radiation. Gamma rays are the highest energy electromagnetic radiation, and they are generated by nuclear processes.

Gamma ray burst is a source of a particular type of cosmic rays. Cosmic rays are high-energy particles arriving at Earth from sources that lie outside it. What exactly is high energy in this definition is not well defined. Practically any stable particle can be a cosmic ray. Thus you may have photons (gamma rays), electrons, protons, nuclei, neutrinos... The most common type of cosmic rays detected on Earth are actually protons. It has to do with the fact, that a high energy proton can travel very large distances without losing significant energy.
