Hence, we infer that gamma rays likely originated with the MGF in Sculptor, and not from a cosmological gamma-ray burst, and we suggest that the GeV signal is generated by an ultra-relativistic outflow that first radiates the prompt MeV-band photons. Our detailed analysis shows that the low-energy emission has very peculiar properties typically observed in flares from nearby magnetars, while the GeV detection is consistent with the IPN localization and spatially associated with the Sculptor galaxy. In this talk we present the recently published results of the GBM and LAT analysis on GRB 200415A. 19 seconds later, and for nearly 300 seconds, the Large Area Telescope (LAT) detected GeV photons in spatial coincidence with the signal at lower energies. On April 15, 2020, a short bright burst of MeV gamma rays triggered the Gamma-Ray Burst Monitor (GBM) aboard the Fermi spacecraft, called GRB 200415A and localized by the InterPlanetary Network (IPN) inside the disk of the nearby Sculptor galaxy. Rarely, magnetars can produce enormous eruptions, called Magnetar Giant Flares (MGF), consisting of short-duration bursts of hard X-rays and soft gamma rays – a bright and variable initial spike lasting a few tenths of a second and a significantly dimmer pulsating tail lasting a few hundred of seconds that can only be detected from MGFs within our close to our galaxy. Magnetars are neutron stars with the strongest magnetic fields known in the Universe, with an intensity up to a thousand times higher than typical neutron stars.

To make full use of the online format, all contributions will be made available one week before the official start of the conference (abstracts and proceedings paper for all contributions presentation slides and pre-recorded presentation videos for the 12-min talks, posters and pre-recorded 2-min flash talks for poster contributions). This allows browsing through the contributions, commenting and asking questions, and coming prepared to the more discussion-like, topical parallel sessions.

We hope to provide an experience to the standards of past ICRCs. The ICRC 2021 will be a prime forum to learn about news and developments in Astroparticle Physics and to appreciate the links between its topics.ĭue to the COVID-19 pandemic, this year’s ICRC will be held entirely online. Broad reviews and recent scientific results, related theory and modelling, experimental methods, techniques and instrumentation will be presented.

Additional new topics in the 2021 conference are Multi-messenger Astronomy and Outreach & Education. The main topics are Cosmic Ray Physics, Gamma-Ray Astronomy, Neutrino Astronomy & Neutrino Physics, Dark Matter Physics and Solar and Heliospheric Physics.

#SEA WOLF EXPRESS RUSSIAN GEV SERIES#

The ICRC Conference Series has been organised biennially since 1947 under the auspices of the International Union of Pure and Applied Physics ( IUPAP) and is the largest conference on Astroparticle Physics, bringing together the different topics of the field.
