Particle acceleration in the Universe, Origin of cosmic rays

We are exploring the high-energy Universe, which cannot be seen in optical light, with gamma-rays. Gamma-rays are emitted from high-energy objects in the Universe, such as supernova remnants, pulsars and pulsar nebulae, and active galactic nuclei. Electrons and protons are accelerated to high energies in these objects and produce gamma-rays via interaction with surrounding radiation and matter. Gamma-rays are the best probe of particle acceleration in the Universe since they travel straight and are not deflected by magnetic fields. In addition, the annihilation of dark matter particles could be detected by gamma-rays. Also we are operating a 60cm optical telescope in the BKC campus to explore timevarying astrophysical objects.
