Data releases (generally fully processed image products and/or catalogues) from various projects can be found in the SARAO repository.

This includes public releases of SARAO legacy surveys, calibrator images from the SARAO monitoring programme, and periodic some data releases from the large survey projects.

Following review, the Report of the MeerKAT Large Project Review Panel resulted in this rank-ordered list of approved LSPs and components:

LSPs will be are being allocated up to 2/3 of the MeerKAT science time to be scheduled over a period of 5 years for projects selected competitively. As of mid-2024, two of the LSPs have already reached their 5-year terms, and as this happens gradually more observing time is allocated to Open Time projects.

No more LSP calls are envisioned at this stage.

Open Time

These projects will use have used up to approximately 28% of the observing time awarded through competitive proposalsprocesses during the first 5 years of MeerKAT operations. There will be periodic are yearly calls for Open Time proposals. The following projects were accepted for the previous open OT calls. Please click on the links for more details.

Open Time 2023 accepted projects

Open TIme 2024 accepted projects

DDT

The DDT mechanism is available to allocate approximately 5% of competitively awarded observing time. Instructions on how to apply can be found here.

...

All of the projects below have used the L-band receiver and 4k mode of the correlator.

The region surrounding the Galactic Center has been surveyed with a variety of pointings. Long tracks have been used to cover approximately |b| < 1°, |l| < 2°; a vertical strip at approximately |b| < 20°, |l| < 1.5° has been covered with a mosaic pointing scheme that achieves 1 hour integration time per pointing spread over a range of hour angles to obtain good uv coverage. The overview paper for the long-tracks portion of the survey has been accepted for publicationpublished, and the corresponding data products are available from the SARAO repository.

The MeerKAT Galaxy Cluster Legacy Survey

Approximately 30 radio-selected and 70 X-ray-selected galaxy clusters have been observed with long tracks. The survey overview and highlights paper has been published, along with the first data release on the SARAO repository.

The data release includes unprocessed visibilities (please read the paper for caveats), basic imaging products, enhanced imaging products and catalogues.

...

Both the SMC and LMC have been surveyed with a mosaic pointing scheme that achieves 1 hour integration time per pointing spread over a range of hour angles to obtain good uv coverage. The SMC survey paper and associated data release have been published. Science exploitation has begun for the LMC survey, and those potentially interested to participate should contact SARAO.

A thin strip of the Southern Galactic Plane (4^th quadrant, and also portions of the 3^rd and 1^st: 248° < l < 61°, |b| < 1.5°) has been surveyed with a mosaic pointing scheme that achieves 1 hour integration time per pointing spread over a range of hour angles to obtain good uv coverage. Science exploitation is underway, and those potentially interested to participate should contact Sharmila GoedhartThe initial survey paper and associated data release have been published.

Science Verification

SARAO has surveyed a 30 deg² region in the GAMA23 field in order to demonstrate MeerKAT's capabilities for relatively shallow and large area neutral hydrogen surveys, while demonstrating the science utility of the SDP near real-time spectral imager. This uses the L-band receiver, 32k mode of the correlator, and 1 hour per pointing. Those potentially interested to participate in the science exploitation of this dataset should contact SARAO.

MPIfR MeerKAT Galactic Plane survey (MMGPS)

This survey is a multi-wavelength campaign incorporating imaging, spectral line and time-domain (including pulsar search) modes commensally. The components of the survey are as follows:
