Gama ışın patlamaları ardıl ışınımlarının fotometrik ve tayf gözlemlerinin yorumu

The short (~0.1-100 seconds) and intense bursts of high energy gamma-ray radiation (>100 keV) are called Gamma-Ray Bursts (GRBs). They occur uniformly in the universe approximately once per day at very high distances to Earth. Their nature and origin have remained a mystery of modern astronomy since GRB were discovered serendipitously in 1967. The results of afterglow observations with ground based telescopes and scientific observations sent after 1990 indicated that GRBs are cosmological objects. In this work, the association of GRBs ? SNe (Supernovae) are studied with the optical spectra of afterglow of some selected GRBs by the 6m-BTA (Bolsoi Azimuthal Telescope) telescope at SAO-RAS (Special Astrophysical Observatory of Russian Academy of Sciences). The host galaxy properties and afterglows are also studied with the photometrical observations of some selected GRBs.
