VLBI with SKAMPI, the SKA-Mid MPIfR dish demonstrator
Jompoj Wongphechauxsorn, Niclas Alexander Esser, Tobias Winchen +13
The SKA-MPIfR telescope (SKAMPI) is a prototype SKA-Mid antenna located at the SKA site in the Karoo Desert, South Africa. It is funded by the Max Planck Society, through the Max P…
Frequency Phase Transfer for Future Millimetre Arrays with Arbitrary Frequency Ratios
Senkhosi Simelane, Athol Kemball, Roger Deane
Non-dispersive tropospheric turbulence-induced phase delays enforce significant, often dominant, limitations to the imaging fidelity and dynamic range in (sub-)millimetre astronomy…
Extending the SKA Across Africa: The Case for a Continental African VLBI Network
Emmanuel K. Bempong-Manful, Jompoj Wongphechauxsorn, Jack Radcliffe +31
The African continent holds the key to unlocking the full potential of global Very Long Baseline Interferometry (VLBI). Strategic placement of radio telescopes across Africa provid…
Prospecting MeerKAT Continuum Data for Enigmatic Radio Sources with Unsupervised Vector-Quantised Variational Autoencoders
Fernando L. Ventura, Kshitij Thorat, Anna Bosman +2
We present a novel application of Vector quantised variational autoencoders (VQ-VAEs) as an unsupervised tool to probe deep 1.28 GHz radio continuum images taken from the MeerKAT G…
Evaluation of South African Candidate Sites for an Expanded Event Horizon Telescope
Senkhosi Simelane, Roger Deane, Athol Kemball +5
Global expansion of the Event Horizon Telescope (EHT) will see the strategic addition of antennas at new geographical locations, transforming the sensitivity and imaging fidelity o…
First Very Long Baseline Interferometry Detections at 870μm
Alexander W. Raymond, Sheperd S. Doeleman, Keiichi Asada +276
The first very long baseline interferometry (VLBI) detections at 870m wavelength (345GHz frequency) are reported, achieving the highest diffraction-limited angular resoluti…
