- Description:
- Apertif is a phased-array feed system for the Westerbork SynthesisRadio Telescope (WSRT), operating at 1.4 GHz and providing forty instantaneous beams over 300 MHz of bandwidth. This data release includes the image of the ELAIS-N field observed with Apertif. The image covers 25 square degree region, has an angular resolution of 18x11 arcseconds and a median background noise of 37 μJy/beam. The corresponding source catalog, complete down to the 0.3 mJy level, includes 8526 sources. https://science.astron.nl/telescopes/wsrt-apertif/apertif-data-access/data-releases/apertif-single-fields/

- Apertif Time Domain FRB detection cone search (DR2)
- Short Name:
- Detected FRB
- Date:

- Publisher:
- ASTRON
- Description:
- This is the final, full data release from the Apertif Radio Transient System (ARTS), a supercomputing radio-telescope instrument that performed real-time FRB detection and localisation on the Westerbork Synthesis Radio Telescope (WSRT) interferometer. It reached coherent-addition sensitivity over the entire field of the view of the primary- dish beam. The Apertif FRB survey (ALERT) detected 24 new FRBs, and interferometrically localised each of these to 0.4−10 sq. arcmin. All detections are broad band and very narrow, of order 1 ms duration, with high dispersion measures. Please note that the ARTS DR2 collection includes all data from the DR1 collection.

- Publisher:
- ASTRON
- Description:
- This is the first release of data from the Apertif Radio Transient System (ARTS), a supercomputing radio-telescope instrument that performs real-time FRB detection and localisation on the Westerbork Synthesis Radio Telescope (WSRT) interferometer. It reaches coherent-addition sensitivity over the entire field of the view of the primary- dish beam. After commissioning results verified the system performed as planned, we initiated the Apertif FRB survey (ALERT). Over the first 5 weeks we observed at design sensitivity in 2019, we detected 5 new FRBs, and interferometrically localised each of these to 0.4−10 sq. arcmin. All detections are broad band and very narrow, of order 1 ms duration, and unscattered. Dispersion measures are generally high. Please note that the ARTS DR1 collection available from this end-point is superseded by the ARTS DR2 collection. DR2 includes all data from the DR1 collection that can be queried here.
