XMM-Newton Resolves Parsec-scale X-ray Jets in the PeVatron Microquasar V4641 Sgr
Naomi Tsuji, Caterina Tresoldi, Kaya Mori +34
The microquasar V4641 Sagittarii (V4641 Sgr) has recently been established as one of the most powerful Galactic PeV cosmic-ray accelerators (PeVatrons) through the detection of deg…
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 Lazarević +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…
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…
Thermal emission from bow shocks. III. Variable diffuse X-ray emission from stellar-wind bow shocks driven by dynamical instabilities
Jonathan Mackey, Arun Mathew, Ahmad A. Ali +5
X-ray emission from wind-driven bow shocks is both difficult to measure and predict, but may give important insights into the energy budget of the hot phase of the ISM by quantifyi…
Diprotodon on the sky. The Large Galactic Supernova Remnant (SNR) G278.94+1.35
Miroslav D. Filipović, S. Lazarević, M. Araya +41
We present a re-discovery of G278.94+1.35 as possibly one of the largest known Galactic supernova remnants (SNR) - that we name Diprotodon. While previously established as a Galact…
A multi-ion non-equilibrium solver for ionised astrophysical plasmas with arbitrary elemental abundances
Arun Mathew, Jonathan Mackey, Maggie Celeste +2
While many astrophysical plasmas can be modelled successfully assuming ionisation and thermal equilibrium, in some cases this is not appropriate and a non-equilibrium approach is r…
Core-collapse supernovae in dense environments -- particle acceleration and non-thermal emission
Robert Brose, Iurii Sushch, Jonathan Mackey
Supernova remnants are known to accelerate cosmic-rays from the detection of non-thermal emission in radio waves, X-rays, and gamma-rays. However, the ability to accelerate cosmic-…
A wind-blown bubble in the Central Molecular Zone cloud G0.253+0.016
J. D. Henshaw, M. R. Krumholz, N. O. Butterfield +16
G0.253+0.016, commonly referred to as "the Brick" and located within the Central Molecular Zone, is one of the densest ( cm) molecular clouds in the Galaxy…
