Search for Astrophysical Transients on Limiting Time Scales and Their Classification Based on INTEGRAL Data
G. Yu. Mozgunov, A. S. Pozanenko, P. Yu. Minaev +7
We have searched for ultra-long (> 100 s) gamma-ray transients in the data from the anticoincidence shield (ACS) of the SPI gamma-ray spectrometer onboard the INTEGRAL orbital obse…

From precursor to afterglow: The complex evolution of GRB 210312B
M. JelÃnek, S. A. Grebenev, P. Yu. Minaev +15
Long gamma-ray bursts (GRBs) are characterized by a brief gamma-ray flash followed by a longer-lasting multiwavelength afterglow. The basic mechanism is largely understood, and the…

Pushchino multibeam pulsar search -- V. The bright FRB 20190203 detected at 111 MHz
S. A. Tyul'bashev, V. A. Samodurov, A. S. Pozanenko +6
We report the discovery of a bright pulse having a dispersion measure (DM) equal to 134.4 \pm 2 pc cm^{-3}, a peak flux density (S_p) equal to 20 \pm 4 Jy and a half-width (W_e) eq…
