description: This work is devoted to the study of the spectral evolution of gamma-ray bursts detected simultaneously in the Konus-Wind and BeppoSAX/WFC experiments. Gamma-ray bursts â are the brightest electromagnetic events in the Universe, accompanied by a huge energy release. These transient phenomena were discovered half-century ago, in the 1960s. The physics behind their nature remains partially unclear. Studying the spectral evolution of gamma-ray burst parameters can help understand physical mechanisms of their central engine. In this work we study a set of 25 gamma-ray bursts registered simultaneously in the Konus-Wind and BeppoSAX/WFC experiments. Time-resolved joint spectral analysis of GRB 970111 burst is conducted. The joint analysis of gamma-ray burst spectra allows us not only to obtain the parameters of the fitting model, but also to estimate the instrumental effects that may influence the final result. Spectral parameters obtained from the analysis of the peak and time-integrated spectra are also compared.
