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…
Advancing extragalactic spectral line studies with the Square Kilometre Array Observatory
Jacco Th. van Loon, Viviana Casasola, Manuela Bischetti +6
We present an overview of the Square Kilometre Array Observatory (SKAO) science potential in the area of extragalactic spectral lines besides 21-cm neutral hydrogen. It highlights…
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…
HI 21-cm absorption in low- and high-excitation radio-loud AGNs at from MALS
P. P. Deka, N. Gupta, J-. K. Krogager +5
We present results from a search of cold neutral gas associated with radio-loud active galactic nuclei (AGNs) at using HI 21-cm absorption measurements from the MeerKAT A…
The MeerKAT Absorption Line Survey (MALS) data release 3: Cold atomic gas associated with the Milky Way
N. Gupta, J. Kerp, S. A. Balashev +15
We present results of a blind search for Galactic HI 21-cm absorption lines toward 19130 radio sources, using 390 pointings of MALS, each pointing centered on a source brighter tha…
The kinematic contribution to the cosmic number count dipole
J. D. Wagenveld, S. von Hausegger, H-R. Klöckner +1
Measurements of the number count dipole with large surveys have shown amplitudes in tension with kinematic predictions based on the observed Doppler dipole of the cosmic microwave…
