General concept of the project: The main idea of the project comes from the current studies of a population of long GRBs associated with supernovae. It is believed that massive Wolf-Rayet stars could be predecessors of such supernova explosions. The presence of Wolf-Rayet stars in our galaxy, in turn, opens up additional possibilities for their detailed study with Kazakhstani mid-size telescopes. The identification of any dependencies between galactic Wolf-Rayet stars and their identification as precursors to supernova explosions in association with cosmological long GRBs would allow, among other things, a prediction for future catastrophic processes in our galaxy connected to GRB explosions.

Goal: Search of new and analysis of known GRBs associated with supernovae aiming to identify patterns and characteristics for subsequent physical interpretation. Observations and analysis of galactic Wolf-Rayet stars to identify patterns and characteristics for their interpretation as progenitors of cosmological GRBs associated with supernovae.

Problems the study is aimed at: The study is aimed at the following problems in this field of knowledge—the association of gamma-ray bursts with supernovae: 1) an increase in general statistics; 2) early and continuous spectral and photometric observations with ground-based optical telescopes; 3) the search for astrophysical objects-precursors of events; 4) analysis of data from open sources in the entire electromagnetic spectrum to identify patterns and characteristics of objects.

The main approaches in research conduction: 1) experimental—search and alert observations with optical telescopes; 2) data analysis—processing and interpretation of own observations, as well as data from open sources over the entire electromagnetic spectrum; 3) theoretical—development of theoretical scenarios and models; 4) numerical modeling—modeling of gamma-ray burst development processes, as well as statistical studies.

Project Objectives:
1. Alert and follow-up ground-based observations of the optical afterglow of gamma-ray bursts aiming to detect events associated with supernovae.
2. Data analysis for the sample of gamma-ray bursts associated with supernovae and developing of the theoretical models.
3. Ground-based program observations in the optical band of the sample of Wolf-Rayet stars in the Milky Way galaxy, and study of their properties as predecessor objects for cosmological gamma-ray bursts associated with supernovae.

Expected results: 1) an increase in the overall statistics of gamma-ray bursts associated with supernovae, including our own observations; 2) theoretical scenarios and models of gamma-ray bursts associated with supernovae; 3) publications in specialized rating journals; 4) at least one publication in journals recommended by CCSES MES RK; 5) the extend of international cooperation by giving a talk at scientific conferences and collaborating with foreign research centers and researchers.
