Databases of Gamma-Ray Bursts’ Optical Observations
Gamma-ray bursts (GRBs) are the most energetic and yet the most
mysterious events in the Universe, which are observed in all ranges of electromagnetic
spectrum from radio-bandwidth up to very high energy of about TeV
energies. Moreover, recently GRBs accompanying gravitational waves produced
in binary neutron starmerging were discovered. Despite on theGRBis initially registering
by space-born gamma-ray omnidirectional detectors or wide field of view
telescopes, the most information for GRB investigation obtained by ground based
optical observations. Optical observations allow investigating not only the properties
of the bursts themselves, but also their ISM surroundings, host galaxies, and
phenomena related toGRBs such as core collapsed supernova and kilonova.Bright
GRB can give unique information suitable for modeling, but optically bright burst
is registered once per 5 years and can be counted on the fingers of one hand. Statistical
analysis is still a main instrument of GRB investigation.We give a review of
available optical databases of GRBs and present the original database constructed
using optical observations of the Space Research Institute GRB Follow-up Network.
We provide examples of some statistical properties of the phenomenon, that
can be studied using these databases and discuss constructing necessary databases
for future investigations.
