Fast Simultaneous Surveys with On-the-Fly Mapping
Suman Chatterjee, Sarvesh Mangla, Sourabh Paul +10
The SKAO is a next-generation radio telescope that will transform our understanding of the formation and evolution of radio galaxies, quasars, transients, and other cosmic sources.…
The MeerKLASS L-band On-the-Fly Continuum Survey: Data Release 1
Sarvesh Mangla, Joseph J. Mohr, Kristof Rozgonyi +8
The MeerKAT Large Area Synoptic Survey (MeerKLASS) collaboration has acquired multiple passes of L-band (856-1712 MHz) scanning observations over a 268 deg sky region. This sca…
The MeerKLASS On-the-Fly continuum survey: pipeline design and validation
Suman Chatterjee, Mario G. Santos, Kristof Rozgonyi +8
The MeerKAT Large Area Synoptic Survey (MeerKLASS) is designed to map large areas of the Southern sky for cosmology using the single-dish HI intensity mapping (IM) technique, while…
Square Kilometre Array Science Data Challenge 3a: foreground removal for an EoR experiment
A. Bonaldi, P. Hartley, R. Braun +179
We present and analyse the results of the Science data challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an EoR foreground-removal community-wide exercise organis…
Radio Frequency Interference from Radio Navigation Satellite Systems: simulations and comparison to MeerKAT single-dish data
Brandon Engelbrecht, Mario G. Santos, José Fonseca +11
Radio Frequency Interference (RFI) is emitted from various sources, terrestrial or orbital, and create a nuisance for ground-based 21cm experiments. In particular, single-dish 21cm…
SkyPy: A package for modelling the Universe
Adam Amara, Lucia F. de la Bella, Simon Birrer +18
SkyPy is an open-source Python package for simulating the astrophysical sky. It comprises a library of physical and empirical models across a range of observables and a command-lin…
The w-effect in interferometric imaging: from a fast sparse measurement operator to super-resolution
Arwa Dabbech, Laura Wolz, Luke Pratley +2
Modern radio telescopes, such as the Square Kilometre Array (SKA), will probe the radio sky over large fields-of-view, which results in large w-modulations of the sky image. This e…
Revisiting the spread spectrum effect in radio interferometric imaging: a sparse variant of the w-projection algorithm
L. Wolz, J. D. McEwen, F. B. Abdalla +2
Next-generation radio interferometric telescopes will exhibit non-coplanar baseline configurations and wide field-of-views, inducing a w-modulation of the sky image, which in turn…
The varying w spread spectrum effect for radio interferometric imaging
Laura Wolz, Filipe B. Abdalla, Rafael E. Carrillo +2
We study the impact of the spread spectrum effect in radio interferometry on the quality of image reconstruction. This spread spectrum effect will be induced by the wide field-of-v…
