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…
An ultraviolet burst oscillation candidate from the low-mass X-ray binary EXO 0748-676
A. Miraval Zanon, F. Ambrosino, G. Illiano +15
X-ray burst oscillations are quasi-coherent periodic signals at frequencies close to the neutron star spin frequency. They are observed during thermonuclear Type I X-ray bursts fro…
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…
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…
The Accretion-Ejection Connection in the Black Hole X-ray Binary MAXI J1820070
Joe S. Bright, Rob Fender, David M. Russell +12
The black hole X-ray binary MAXI J1820070 began its first recorded outburst in March 2018, and remained an active radio, X-ray, and optical source for over four years. Due to th…
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…
