A curated portfolio of end-to-end SKA simulations: from synthetic sky models to visibilities, dirty and CLEANed images, and UV coverage across the world's most powerful radio interferometers, created with skasim and powered by the Karabo pipeline.
A 1.28 GHz continuum field observed with MeerKAT L-band, SKA1-MID Band 1/2, and the VLA in B and D configurations. All runs share the MIGHTEE DR1 sky model and a matched 0.2° field of view.

A 2 h SKA-LOW-AAstar observation at 175 MHz of a 1° field filled with 60 462 T-RECS sources. Two faint, 80% circularly polarized sources lost in the confused Stokes I image are recovered blindly in Stokes V at +8.1σ and −6.3σ, with no false positives.

Exploring the chronological staged delivery of the SKA telescopes, from the initial AA0.5 verification array to the full AA4 design baseline. Each assembly is simulated on a 0.6° portion of the SKA Data Challenge 1 catalogue with sources down to 10 μJy.

Arp 220 and Arp 299 placed at z = 0.15, 0.30, 0.50, 1.00 and 2.00, observed with SKA-MID-AA* at 1.35, 6.5 and 11.9 GHz. Cosmological dimming, angular-size scaling and SFR evolution applied to the same resolved radio galaxy model.

A pyHIARD spiral galaxy observed in the 21-cm line with SKA-MID-AA* for 20 min, seen nearly face-on, at 45° and nearly edge-on. Moment maps and position–velocity diagrams show how much of the rotation each geometry recovers.
Read the case →skasim orchestrates OSKAR/Karabo for visibility simulation, CASA for image-model injection, WSClean for imaging, and shadeMS for uv-coverage diagnostics.
Catalogs, component lists, or FITS images with continuum Stokes I and spectral index.
OSKAR/Karabo generates Measurement Sets for the requested telescope, frequency, and integration.
WSClean with configurable Briggs robust, niter, pixels, and FoV; dirty images via OSKAR.
Weblog with previews, FITS downloads, metadata JSON, and shadeMS uv-coverage plots.
Preparing Spanish research groups and technologies for the Square Kilometre Array.
CSIC4SKA is a espSRC-coordinated initiative with the goal of enhancing CSIC members' participation in international collaborations for SKA Key Science Projects, increasing visibility of CSIC studies within the SKA international community, and foster scientific and technological cooperation.
skasim is a modular SKA simulator for creating synthetic radio-interferometric observations of the SKA (Square Kilometre Array) and precursors. It bridges user-supplied sky models and simulated imaging data products, supporting feasibility studies, definition of science cases and pipeline validation for the SKA community.
