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…
The Physics of the Nebular Phase in Black Hole X-ray Binaries: Modelling V404 Cygni
A. Ambrifi, T. Muñoz-Darias, J. A. Fernández-Ontiveros +3
Some of the most extreme galactic black hole transients exhibit a nebular phase at the end of their outbursts. This stage was first identified in the 2015 outburst of V404 Cygni, w…
Simulation-based inference for AGN jet population modelling: Towards more robust comparisons of black hole jet speeds
Clara Lilje, James H. Matthews, Rob Fender
We present the most complete modelling of the MOJAVE 1.5 Jansky Quarter Century active galactic nuclei (AGN) jet population, using likelihood-free simulation-based inference. Due t…
A MIGHTEE robust measurement of the star formation rate-radio correlation
Charlotte L. Jackson, Matt J. Jarvis, Imogen H. Whittam +9
Determining the relationship between star-formation rate (SFR) and the radio luminosity () is critical if we are to trace the star-formation history of the Universe dust-a…
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 Homogeneous MeerKAT and Swift/XRT X-ray Binary Radio:X-ray Plane
Justine Crook-Mansour, Rob Fender, Andrew Hughes +22
During the hard and quiescent spectral states in X-ray binaries, a non-linear correlation is observed between radio and X-ray luminosities, providing a valuable tool to probe the c…
Spin Demographics of Active Supermassive Black Holes: Updated Estimates from X-ray reflection and Future opportunities
Julia M. Sisk-Reynes, Christopher S. Reynolds, James H. Matthews +5
Understanding the growth of supermassive black holes (SMBHs) requires observational constraints on how their angular momentum (or spin) varies with mass, since the relative importa…
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…
Simulating radio emission from flickering AGN jets: travelling shocks and hotspot brightening
Emma L. Elley, James H. Matthews, Dipanjan Mukherjee +1
We investigate the impact of flickering variability in jet power on the luminosity and morphology of radio galaxies. We use a Lagrangian particle method together with relativistic…
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…
Kinematics show consistency between stellar mass and supermassive black hole parent population jet speeds
Clara Lilje, Rob Fender, James H. Matthews
Jets from stellar-mass and supermassive black holes provide the unique opportunity to study similar processes in two very different mass regimes. Historically, the apparent speeds…
Exploring the quasar disc-wind-jet connection with LoTSS and SDSS
Charlotte L. Jackson, James H. Matthews, Imogen H. Whittam +4
We investigate the relationship between disc winds, radio jets, accretion rates and black hole masses of a sample of 100k quasars at z 2. Combining spectra from the…
