My research focuses on gamma-ray bursts (GRBs), which are the Universe's most energetic transient phenomena. As objects that sample the entire observable Universe in space and time, GRBs are crucial in extragalactic astrophysics, especially since their joint detection with gravitational waves.I've analyzed the celestial and spatial distribution of GRBs and their relationship with the large-scale structure of the Universe. I worked with spatial two-point correlation functions, taking into account sky coverage and radial distribution. Our results indicate large-scale inhomogeneities in GRB data, the origin of which is still unknown.I developed the ADWO procedure for analyzing high-energy satellite data. This method utilizes multi-channel/multi-detector capabilities to simulate a virtual detector, maximizing information extraction. Currently, I am working on a more precise reconstruction of the detector background, which can improve detection sensitivity, especially for cross-correlation studies.My further research includes investigating the distribution of GRBs, their redshift, and sky-coverage functions, as well as analyzing spectral and physical parameters using data from the Swift and Fermi satellites. I am also participating in the preparation of the ESA Theseus satellite white paper and conducting related simulations.
