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…
The odyssey of the black hole low mass X-ray binary GX339-4: Five years of dense multi-wavelength monitoring
E. Tremou, S. Corbel, R. Fender +15
We present the longest and the densest quasi-simultaneous radio, X-ray and optical campaign of the black hole low mass X-ray binary GX339-4, covering five years of weekly GX339-4 m…
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…
A MeerKAT survey of nearby dwarf novae: I. New detections
J. Kersten, E. Körding, P. A. Woudt +8
A program to search for radio emission from dwarf-novae-type cataclysmic variables was conducted with the South African MeerKAT radio telescope. The dwarf novae RU Pegasi, V426 Oph…
MeerKAT caught a Mini Mouse: serendipitous detection of a young radio pulsar escaping its birth sit
S. E. Motta, J. D. Turner, B. Stappers +4
In MeerKAT observations pointed at a Galactic X-ray binary located on the Galactic plane we serendipitously discovered a radio nebula with cometary-like morphology. The feature, wh…
The 2019 outburst of AMXP SAX J1808.4-3658 and radio follow up of MAXI J0911-655 and XTE J1701-462
K. V. S. Gasealahwe, I. M. Monageng, R. P. Fender +14
We present radio coverage of the 2019 outburst of the accreting millisecond X-ray pulsar SAX J1808.4-3658, obtained with MeerKAT. We compare these data to contemporaneous X-ray and…
Radio observations of the Black Hole X-ray Binary EXO 1846-031 re-awakening from a 34-year slumber
D. R. A. Williams, S. E. Motta, R. Fender +15
We present radio [1.3 GHz MeerKAT, 4-8 GHz Karl G. Jansky Very Large Array (VLA) and 15.5 GHz Arcminute Microkelvin Imager Large Array (AMI-LA)] and X-ray (Swift and MAXI) data fro…
21 new long-term variables in the GX 339-4 field: two years of MeerKAT monitoring
L. N. Driessen, B. W. Stappers, E. Tremou +14
We present 21 new long-term variable radio sources found commensally in two years of weekly MeerKAT monitoring of the low-mass X-ray binary GX 339-4. The new sources vary on time s…
Search and identification of transient and variable radio sources using MeerKAT observations: a case study on the MAXI J1820+070 field
A. Rowlinson, J. Meijn, J. Bright +11
Many transient and variable sources detected at multiple wavelengths are also observed to vary at radio frequencies. However, these samples are typically biased towards sources tha…
A MeerKAT, e-MERLIN, H.E.S.S. and Swift search for persistent and transient emission associated with three localised FRBs
James O. Chibueze, M. Caleb, L. Spitler +156
We report on a search for persistent radio emission from the one-off Fast Radio Burst (FRB) 20190714A, as well as from two repeating FRBs, 20190711A and 20171019A, using the MeerKA…
The black hole transient MAXI J1348-630: evolution of the compact and transient jets during its 2019/2020 outburst
F. Carotenuto, S. Corbel, E. Tremou +14
We present the radio and X-ray monitoring campaign of the 2019/2020 outburst of MAXI J1348-630, a new black hole X-ray binary (XRB) discovered in 2019 January. We observed MAXI J13…
Radio and optical observations of the possible AE Aqr twin, LAMOST J024048.51+195226.9
M. L. Pretorius, D. M. Hewitt, P. A. Woudt +8
Thorstensen (2020) recently argued that the cataclysmic variable (CV) LAMOST J024048.51+195226.9 may be a twin to the unique magnetic propeller system AE Aqr. If this is the case,…
The Galactic center chimneys: The base of the multiphase outflow of the Milky Way
G. Ponti, M. R. Morris, E. Churazov +2
Outflows and feedback are key ingredients of galaxy evolution. Evidence for an outflow arising from the Galactic center (GC) has recently been discovered at different wavelength. W…
A MeerKAT Survey of Nearby Novalike Cataclysmic Variables
D. M. Hewitt, M. L. Pretorius, P. A. Woudt +17
We present the results of MeerKAT radio observations of eleven nearby novalike cataclysmic variables. We have detected radio emission from IM Eri, RW Sex, V3885 Sgr and V603 Aql. W…
MKT J170456.2-482100: the first transient discovered by MeerKAT
