Autor: Guidorzi, C., Maccary, R., Tsvetkova, A., Kobayashi, S., Amati, L., Bazzanini, L., Bulla, M., Camisasca, A. E., Ferro, L., Frederiks, D., Frontera, F., Lysenko, A., Maistrello, M., Ridnaia, A., Svinkin, D., Ulanov, M.

At the dawn of the gamma-ray burst (GRB) afterglow era, a Cepheid-like correlation was discovered between time variability V and isotropic-equivalent peak luminosity Liso of the prompt emission of about a dozen long GRBs with measured redshift availa

Long gamma ray bursts (GRBs) are produced by the collapse of some very massive stars, which emit ultra-relativistic jets. When the jets collide with the interstellar medium they decelerate and generate the so-called afterglow emission, which has been

GRB 210619B: first gamma-ray burst detection by the novel polarimeter MOPTOP

Autor: Shrestha, M., Steele, I. A., Kobayashi, S., Smith, R. J., Jermak, H., Piascik, A., Mundell, C. G.

GRB~210619B was a bright long gamma-ray burst (GRB) which was optically followed up by the novel polarimeter MOPTOP on the Liverpool Telescope (LT). This was the first GRB detection by the instrument since it began science observations. MOPTOP starte
