EMU discovery of Thunder: a bow-shock PWN powered by PSR J1631-4722 escaping Nimbus SNR (G336.7+0.5)
S. LazareviÄ, C. Maitra, A. Ahmad +21
We report the discovery of a bow-shock pulsar wind nebula (PWN), dubbed Thunder, powered by the radio pulsar PSR J1631-4722 and projected within the Galactic supernova remnant (SNR…
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…
Radio detection of supernova remnant G310.7-5.4 with -ray counterpart: Abeona SNR
Christopher Burger-Scheidlin, Brianna D. Ball, Sanja LazareviÄ +10
G310.7-5.4 is a supernova remnant (SNR) candidate identified as a faint shell in the second epoch Molonglo Galactic Plane Survey (MGPS-2), but this has not been followed up with mu…
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…
H.E.S.S. observations of SN 2024ggi
Jowita Borowska-Naguszewska, Robert Brose, Bernardo Cornejo +3
Supernova (SN) explosions interacting with dense circumstellar medium are considered to be very promising sites for efficient cosmic-ray (CR) acceleration and subsequent emission o…
Teleios (G305.4-2.2) -- the mystery of a perfectly shaped new Galactic supernova remnant
Miroslav D. Filipovic, Zachary J. Smeaton, Roland Kothes +35
We present the serendipitous radio-continuum discovery of a likely Galactic supernova remnant (SNR) G305.4-2.2. This object displays a remarkable circular symmetry in shape, making…
