Gamma Ray Burst

Gamma-ray burst

Gamma waves, located at the short-wave limit of electro-magnetic spectrum, are of huge energies.
The bursts of gamma rays attract special attention of astrophysicists and cosmologists, since not only their manifestations indicate that we observe them from outside of our galaxy, but also they are the most powerful energy sources in the universe.

Although we have learned a lot about GRBs, many pieces of this puzzle are missing, as the physics (mechanism) that produces the light we see. However, we know such parameters as the duration and power of GRB and the spectrum of its afterglow, which allows us to build a scale of distances in the universe.

The burst alerts are received from GRB coordinate network within seconds after its detection by NASA’s Swift satellite. The slope of the spectrum in the optical spectral range has never been measured before and we plan to be the first. A fully automated pre-programmed CDK700 telescope from Plane wave Instruments is going to be installed at Assi Turgen, NU’s first cosmic observatory.
The optical measurements will be made with the Burst Simultaneous Three-Channel Instrument (BSTI), designed by Dr. Grossan et al. It is in process of fabrication with the help of the NU Engineering Department’s Prof. Christos Spitas and Aizat Kashkimbayev. The master’s student Magzhan Kistaubayev is working on his thesis testing our principles and cameras.
