Spectropolarimetric detection of baryonic mass loading in a transient relativistic jet: application to the black hole X-ray binary Swift J1727.81613
A. K. Hughes, R. P. Fender, G. R. Sivakoff +10
Radio emission during X-ray binary outbursts is dominated by synchrotron radiation from relativistic jets, but is usually studied through total-intensity diagnostics such as flux d…
Dense, multi-phase accretion disk atmosphere in the low-luminosity state of black hole transientV4641 Sgr
Zuobin Zhang, Rob Fender, James H. Matthews +11
We present soft X-ray spectroscopy of the black-hole X-ray binary V4641~Sgr with the \textit{XMM-Newton} Reflection Grating Spectrometer (RGS). The RGS spectrum shows narrow emissi…
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…
Large-scale radio bubbles around the black hole transient V4641 Sgr
Noa Grollimund, Stéphane Corbel, Rob Fender +7
Black holes (BHs) in microquasars can launch powerful relativistic jets that have the capacity to travel up to several parsecs from the compact object and interact with the interst…
A MeerKAT view of the parsec-scale jets in the black-hole X-ray binary GRS 1758-258
I. Mariani, S. E. Motta, P. Atri +5
Jets from accreting black hole (BH) X-ray binaries (XRBs) are powerful outflows that release a large fraction of the accretion energy to the surrounding environment, providing a fe…
A relativistic jet from a neutron star breaking out of its natal supernova remnant
K. V. S. Gasealahwe, K. Savard, I. M. Monageng +10
The young neutron star X-ray binary, Cir X-1, resides within its natal supernova remnant and experiences ongoing outbursts every 16.5 days, likely due to periastron passage in an e…
Monte-Carlo radiation hydrodynamic simulations of line-driven disc winds: relaxing the isothermal approximation
Amin Mosallanezhad, Christian Knigge, Nicolas Scepi +4
Disc winds play a crucial role in many accreting astrophysical systems across all scales. In accreting white dwarfs (AWDs) and active galactic nuclei (AGN), radiation pressure on s…
Comprehensive Radio Monitoring of the Black Hole X-ray Binary Swift J1727.81613 during its 20232024 Outburst
Andrew K. Hughes, Francesco Carotenuto, Thomas D. Russell +39
This work presents comprehensive multi-frequency radio monitoring of the black hole low-mass X-ray binary Swift J1727.81613, which underwent its first recorded outburst after it…
Relativistic ejecta from stellar mass black holes: insights from simulations and synthetic radio images
Katie Savard, James H. Matthews, Rob Fender +1
We present numerical simulations of discrete relativistic ejecta from an X-ray binary (XRB) with initial conditions directly informed by observations. XRBs have been observed to la…
MeerKAT discovers a jet-driven bow shock near GRS 1915+105. How an invisible large-scale jet sculpts a microquasar's environment
S. E. Motta, P. Atri, James H. Matthews +5
Black holes, both supermassive and stellar-mass, impact the evolution of their surroundings on a large range of scales. While the role of supermassive black holes is well studied,…
Quantifying jet-interstellar medium interactions in Cyg X-1: Insights from dual-frequency bow shock detection with MeerKAT
P. Atri, S. E. Motta, Jakob van den Eijnden +6
Accretion and outflows are astrophysical phenomena observed across a wide range of objects, from white dwarfs to supermassive black holes. Developing a complete picture of these pr…
Jets from a stellar-mass black hole are as relativistic as those from supermassive black holes
Xian Zhang, Wenfei Yu, Francesco Carotenuto +15
Relativistic jets from supermassive black holes in active galactic nuclei are amongst the most powerful phenomena in the universe, acting to regulate the growth of massive galaxies…
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…
The origin of the very-high-energy radiation along the jet of Centaurus A
Cainã de Oliveira, James H. Matthews, Vitor de Souza
As the closest known active galactic nucleus, Centaurus A (Cen A) provides a rich environment for astrophysical exploration. It has been observed across wavelengths from radio to g…
Galaxy scale consequences of tidal disruption events: extended emission line regions, extreme coronal lines and infrared-to-optical light echoes
Andrew Mummery, Muryel Guolo, James Matthews +3
Stars in galactic centers are occasionally scattered so close to the central supermassive black hole that they are completely disrupted by tidal forces, initiating a transient accr…
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…
