SN 2007it on the RISE -- a radio detection of an interacting supernova 18 years post-explosion
F. Acero, R. Z. E. Alsaberi, M. Arias +17
We report the first detection of radio emission from the Type II supernova SN 2007it, located at a distance of 12.2 Mpc in NGC 5530. The observations were obtained with the Austral…
Interacting supernovae and where to find them
Robert Brose, Iurii Sushch, Jonathan Mackey +1
Early interaction of supernova blast waves with CSM has the potential to accelerate particles to PeV energies, although this has not yet been detected. Current models for this inte…
Ukrainian Wartime Astronomy and its Prospects
Danilo Albergaria, Kateryna Frantseva, Pedro Russo +20
The Russian invasion of Ukraine damaged or compromised astronomical facilities and has prompted the displacement of researchers. A plan to restore Ukrainian astronomy, rooted in a…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Supernova remnants in super bubbles as cosmic ray accelerators
Iurii Sushch, Pasquale Blasi, Robert Brose
Supernova remnants (SNRs) are often considered as the main sites of acceleration of cosmic rays in our Galaxy, possibly up to the knee. However, their ability to accelerate particl…
How to turn a Supernova into a PeVatron
Robert Brose, Iurii Sushch, Jonathan Mackey
Context. It is important to determine which Galactic cosmic-ray sources can accelerate particles to the knee of the cosmic ray spectrum at a few PeV, and in particular whether supe…
