Radio Properties of RS Canum Venaticorum Variables in VLASS and RACS
Suhasini S. Rao, Gregory R. Sivakoff, Craig O. Heinke +6
We performed a systematic search for radio emission from RS Canum Venaticorum (RS CVn) binaries, selected from the International Variable Star Index (VSX) catalog, in the Very Larg…
VASTER: The ASKAP real-time fast-imaging pipeline -- overview and discovery of two long period transients
Yuanming Wang, Dougal Dobie, Tara Murphy +22
Recent developments in widefield radio telescopes have enabled searches of a new region of parameter space in the time domain: timescales of seconds to minutes, that have been over…
Periodic Radio and X-ray Emission from an Accreting White Dwarf Binary
Kovi Rose, Joshua Pritchard, Tara Murphy +26
Long period radio transients (LPTs) are coherent bursts of polarised radio emission that repeat periodically on timescales of minutes to hours. Little is known about the physical o…
A broadband search for coherent radio emission in cataclysmic variables
Margaret E. Ridder, Paul E. Barrett, Craig O. Heinke +1
Radio observations of cataclysmic variables have revealed a variety of behavior. From some systems, we see bright unpolarized radio flares occurring during dwarf nova outbursts, co…
The ASKAP Variables and Slow Transients (VAST) Extragalactic Survey - Data Release 1
Iris de Ruiter, Dougal Dobie, Tara Murphy +13
The Variables and Slow Transients (VAST) Survey on the Australian SKA Pathfinder (ASKAP) is designed to systematically explore the dynamic radio sky, detecting sources that vary on…
ASKAP J144834-685644: a newly discovered long period radio transient detected from radio to X-rays
Akash Anumarlapudi, David L. Kaplan, Nanda Rea +13
Long-period radio transients (LPTs) are an emerging group of radio transients that show periodic polarized radio bursts with periods varying from a few minutes to a few hours. Fewe…
Discovery of Main-sequence Radio Pulse emitters from widefield sky surveys
Barnali Das, Matt E. Shultz, Joshua Pritchard +6
Magnetic AB stars are known to produce periodic radio pulses by the electron cyclotron maser emission (ECME) mechanism. Only 19 such stars, known as 'Main-sequence Radio Pulse emit…
VAST-MeMeS: Characterising non-thermal radio emission from magnetic massive stars using the Australian SKA Pathfinder
Barnali Das, Laura N. Driessen, Matt E. Shultz +7
Magnetic massive stars are stars of spectral types O, B and A that harbour kG strength (mostly dipolar) surface magnetic fields. Their non-thermal radio emission has been de…
Radio detections of two unusual cataclysmic variables in the VLA Sky Survey
Margaret E Ridder, Craig O Heinke, Gregory R Sivakoff +1
We report two new radio detections of cataclysmic variables (CVs), and place them in context with radio and X-ray detections of other CVs. We detected QS Vir, a low accretion-rate…
Radio monitoring of transient Be/X-ray binaries and the inflow-outflow coupling of strongly-magnetized accreting neutron stars
J. van den Eijnden, N. Degenaar, T. D. Russell +5
Strongly-magnetized ( G) accreting neutron stars (NSs) are prime targets for studying the launching of jets by objects with a solid surface; while classical jet-launc…
Disk-jet coupling changes as a possible indicator for outbursts from GX 339-4 remaining within the X-ray hard state
S. E. M. de Haas, T. D. Russell, N. Degenaar +8
We present quasi-simultaneous radio, (sub-)millimetre, and X-ray observations of the Galactic black hole X-ray binary GX 339-4, taken during its 2017--2018 outburst, where the sour…
The X-ray Emissivity of Low-Density Stellar Populations
C. O. Heinke, M. G. Ivanov, E. W. Koch +17
The dynamical production of low-mass X-ray binaries and brighter cataclysmic variables (CVs) in dense globular clusters is well-established. We investigate how the X-ray emissivity…
Revealing the Origin and Cosmic Evolution of Supermassive Black Holes
T. E. Woods, R. M. Alexandroff, S. L. Ellison +14
The next generation of electromagnetic and gravitational wave observatories will open unprecedented windows to the birth of the first supermassive black holes. This has the potenti…
The 2018 outburst of BHXB H1743-322 as seen with MeerKAT
D. R. A. Williams, S. E. Motta, R. Fender +11
In recent years, the black hole candidate X-ray binary system H1743-322 has undergone outbursts and it has been observed with X-ray and radio telescopes. We present 1.3 GHz MeerKAT…
Extreme Jet Ejections from the Black Hole X-ray Binary V404 Cygni
A. J. Tetarenko, G. R. Sivakoff, J. C. A Miller-Jones +14
We present simultaneous radio through sub-mm observations of the black hole X-ray binary (BHXB) V404 Cygni during the most active phase of its June 2015 outburst. Our hour long…
Rapid Radio Flaring during an Anomalous Outburst of SS Cyg
K. P. Mooley, J. C. A. Miller-Jones, R. P. Fender +12
The connection between accretion and jet production in accreting white dwarf binary systems, especially dwarf novae, is not well understood. Radio wavelengths provide key insights…
