Kink instability as a particle acceleration mechanism in X-ray binaries and the connection to the outburst cycle
Emma L. Elley, James H. Matthews, Alex J. Cooper +2
We consider whether the kink instability can explain particle acceleration in hard state 'compact' X-ray binary jets. We apply a 1D model to assess the expected growth rate of the…
Observational Biases and Improved Modelling of Off-axis Relativistic Jets
A. J. Cooper, A. P. Scott, L. Rhodes +8
Relativistic Doppler boosting significantly affects the observed emission of astrophysical jets resulting in observational biases. In this work we investigate the observational bia…
The impact of flickering variability and magnetisation on the dynamics, stability and morphology of radio-loud AGN jets
Emma L. Elley, James H. Matthews, Henry Whitehead +1
The physics governing the morphology of radio-loud AGN jets is not fully understood. We investigate how magnetization, flickering jet power and their interplay affects the morpholo…
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…
Constraining the physical properties of large-scale jets from black hole X-ray binaries and their impact on the local environment with blast-wave dynamical models
Francesco Carotenuto, Rob Fender, Alexandra J. Tetarenko +5
Relativistic discrete ejecta launched by black hole X-ray binaries (BH XRBs) can be observed to propagate up to parsec-scales from the central object. Observing the final decelerat…
