Abstract
Recent results of the international High Energy Astronomy Research Team (HEART, a Czech, Japanese, American, and Hungarian collaboration) are presented. Our multi‐messenger investigations revealed the properties of γ‐ray bursts (GRB) and their host environments. We analyzed Fermi measurement data with our ADWO method, which appeared as a handy tool for identifying short and intermediate‐long GRBs, such as GRB170817. By studying the GRBs' spatial distribution, we discovered two of the largest known formations in the Universe: the Giant GRB Ring, and the Hercules‐Corona Borealis Great Wall. We used faar infrared imaging photometry data to resolve the fine structure and composition of the Galactic foreground interstellar medium (ISM) in the direction of GRBs. This resulted in an increase in the precision of calculating the column density of intrinsic ISM at the GRBs in their host galaxies.
