Dynamic shocks powered by a wide, relativistic, super-Eddington outflow launched by an accreting neutron star in the mid-20th century
F. J. Cowie, R. P. Fender, I. Heywood +11
Accreting systems can launch powerful outflows which interact with the surrounding medium. We combine new radio observations of the accreting neutron star X-ray binary (XRB) Circin…
Cosmic rays, gamma rays and neutrinos from discrete black hole X-ray binary ejecta
Nicolas J. Bacon, Alex J. Cooper, Dimitrios Kantzas +2
The origin of cosmic rays from outside the Solar system are unknown, as they are deflected by the interstellar magnetic field. Supernova remnants are the main candidate for cosmic…
Exploring the potential for ultra-relativistic jets in Scorpius X-1 with low angular resolution radio observations
I. Stephens, L. Rhodes, A. J. Cooper +2
Scorpius X-1 (Sco X-1) is a neutron star X-ray binary in which the neutron star is accreting rapidly from a low mass stellar companion. At radio frequencies, Sco X-1 is highly lumi…
Relativistic precessing jets powered by an accreting neutron star
F. J. Cowie, R. P. Fender, I. Heywood +9
Precessing relativistic jets launched by compact objects are rarely directly measured, and present an invaluable opportunity to better understand many features of astrophysical jet…
Blast waves and reverse shocks: from ultra-relativistic GRBs to moderately relativistic X-ray binaries
James H. Matthews, Alex J. Cooper, Lauren Rhodes +8
Blast wave models are commonly used to model relativistic outflows from ultra-relativistic gamma-ray bursts (GRBs), but are also applied to lower Lorentz factor ejections from X-ra…
Joint Radiative and Kinematic Modelling of X-ray Binary Ejecta: Energy Estimate and Reverse Shock Detection
A. J. Cooper, J. H. Matthews, F. Carotenuto +6
Black hole X-ray binaries in outburst launch discrete, large-scale jet ejections which can propagate to parsec scales. The kinematics of these ejecta appear to be well described by…
