Gamma-Ray Bursts and Puzzles of Core-Collapse Supernovae

Discovery of relation between long-duration gamma-ray bursts (GRBs) and supernovae (SNe) is the most important progress in this domain during recent 10 years. Now the search for SNe signs in photometry and spectra of GRB aftrdglows became the main observational direction both for large ground-based telescopes and space platforms.
In particular, in the process of study, a new branch of observational cosmology has arisen as a result of investigations of GRB host galaxies.
The GRBs themselves are already considered as a tool for studying processes of star-forming at cosmological distances up to redshifts z~10. Irrespective of specific models of this phenomenon, it might be said now that when observing GRBs we observe the most distant SN explosions which, probably, are ALWAYS connected to the relativistic collapse of massive stellar cores in very distant galaxies. The connection is that GRBs may serve as a guideline to better understand the mechanism, and possibly solve the long-standing problem of the core-collapse SN explosion, since in the GRBs we have additional information related to the core-collapse.
This report is about one of the most mysterious phenomenon of the modern astronomy - GRBs.
