From the Astronomer's Telegram
- Since the discovery of FRB 20240114A by CHIME/FRB (ATel 16420), observatories around the world have continued monitoring observations while it remains active. Over 100 bursts have been detected with small radio telescopes across Europe at 330 MHz and 1.4 GHz (ATel 16565); 5 bursts at 2.5 GHz with Nancay (ATel 16597), and 8 bursts spanning 1.2 to 2.2 GHz at the Allen Telescope Array (ATel 16599). In particular, one ATA detection spans over 800 MHz in bandwidth. There is also a report of a potential excess of gamma rays in Fermi LAT observations in the general vicinity of the repeating FRB source (ATel 16594), but that is ruled out by a different analysis of Fermi LAT data (ATel 16602).
Meetings and conference news
- At the Seventeenth Marcel Grossmann meeting in Pescara, 7-12 July 2024, there will be a Parallel Session entitled: "Galactic and extragalactic magnetars: recent observations and theoretical progress". This parallel session, chaired by Simone Dall'Osso and Sandro Mereghetti, will focus on the most recent observational results on Galactic and extraGalactic magnetars, as well as on the theoretical developments on their structure, formation and connections with other astrophysical phenomena (such as, e.g., fast radio bursts, gamma-ray bursts, super luminous supernovae, sources of high-energy cosmic rays, neutrinos and gravitational waves).
