The October 2022 flare in OJ 287 and the mass of its primary black hole
Mauri J. Valtonen, Staszek Zola, Manpreet Singh +21
The bright blazar OJ~287 has demonstrated a sequence of flares, which are well explained by a quasi-Keplerian orbit model. The flares are associated with the impact of the secondar…
An extremely bright slow-rising afterglow from an off-axis jet in GRB 260310A
Yu-Han Yang, Roberto Ricci, Eleonora Troja +31
We present a multi-wavelength study of GRB 260310A, a nearby long-duration gamma-ray burst at associated with a broad-lined Type Ic supernova. Despite its modest pro…
Prospects for the detection of gamma rays using Cherenkov telescopes enhanced by a ground array observatory
C. Alispach, A. Araudo, A. Bakalová +67
We study through detailed simulated data and their optimized analysis the expected performance of the Single-Mirror Small-Size imaging atmospheric Cherenkov Telescopes (SST-1M) pot…
Identifying the secondary jet in the RadioAstron image of OJ~287
Mauri J. Valtonen, Lankeswar Dey, Staszek Zola +26
The 136 year long optical light curve of OJ~287 is explained by a binary black hole model where the secondary is in a 12 year orbit around the primary. Impacts of the secondary on…
The SST-1M stereoscopic system
C. Alispach, A. Araudo, M. Balbo +63
The Single-Mirror Small-Size Telescope (SST-1M) is an Imaging Atmospheric Cherenkov Telescope designed for detecting very high-energy gamma rays. With a compact design achieved thr…
Early steep optical decay linked to reverse shock for GRB200131A
Martin Jelínek, Filip Novotný, Sylvio Klose +3
We observed an optical afterglow of GRB 200131A obtaining the first photometric point 63 s after the satellite trigger. This early observation shows a steep decay, suggesting eithe…
