cds-question@unistra.frgamma-ray-astronomygamma-ray-burstsradio-sourcesWe present the Arcminute Microkelvin Imager (AMI) Large Array catalogue of 139 gamma-ray bursts (GRBs). AMI observes at a central frequency of 15.7GHz and is equipped with a fully automated rapid-response mode, which enables the telescope to respond to high-energy transients detected by Swift. On receiving a transient alert, AMI can be on-target within 2-min, scheduling later start times if the source is below the horizon. Further AMI observations are manually scheduled for several days following the trigger. The AMI GRB programme probes the early-time (<1d) radio properties of GRBs, and has obtained some of the earliest radio detections (GRB 130427A at 0.36 and GRB 130907A at 0.51d post-burst). As all Swift GRBs visible to AMI are observed, this catalogue provides the first representative sample of GRB radio properties, unbiased by multiwavelength selection criteria. We report the detection of six GRB radio afterglows that were not previously detected by other radio telescopes, increasing the rate of radio detections by 50 per cent over an 18-month period. The AMI catalogue implies a Swift GRB radio detection rate of >~15 per cent, down to ~0.2mJy/beam. However, scaling this by the fraction of GRBs AMI would have detected in the Chandra & Frail (2012, Cat. J/ApJ/746/156) sample (all radio-observed GRBs between 1997 and 2011), it is possible ~44-56 per cent of Swift GRBs are radio bright, down to ~0.1-0.15mJy/beam. This increase from the Chandra & Frail (2012, Cat. J/ApJ/746/156) rate (~30 per cent) is likely due to the AMI rapid-response mode, which allows observations to begin while the reverse-shock is contributing to the radio afterglow.2018MNRAS.473.1512Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/473/1512CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/51 : GRB list (1990-2014) (Ruggeri+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/473/1512https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/473/1512http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/473/1512https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/473/1512https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/473/1512http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/473/1512GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/473/1512/table1 (The AMI 15.7GHz GRB catalogue: GRBs that have been detected or possibly detected with AMI)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/473/1512/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/473/1512/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/473/1512/table1?GETtext/xml+votable180.050000true212.51791678.69646110.005555555555555556Cone search capability for table J/MNRAS/473/1512/table2 (The AMI 15.7GHz GRB catalogue: GRBs that were not detected with AMI, have a possible steady source association or a concatenated detection)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/473/1512/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/473/1512/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/473/1512/table2?GETtext/xml+votable180.050000true47.53637528.49191670.0055555555555555566/207 211 590 825 866 962 1001 1882 2336 2385 2473 2574 2682 2948 3089 3675 3965 4312 4371 4595 4800 4809 5073 5162 5606 5791 6521 6523 6758 7084 7276 7356 7466 7558 7589 7750 7951 8021 8318 8459 8693 8733 9022 9321 9325 9341 9576 9612 9643 9662 9860 9897 10046 10178 10363 10401 10407 10424 10482 10602 10704 10941 11058 11140 11177 11218 11220 11300 11372 11456 11713 11822 12006 12071 12155 12226 12230 12785 13293 13651 13828 13889 14325 14372 14517 14567 14616 15144 15320 15383 15406 15422 15485 15498 15530 15653 15790 16057 16254 16367 19610 19946 20011 20372 20401 20460 22619 23514 23782 24007 24145 24152 24495 26076 26452 26910 27302 27307 27320 27983 28032 28071 28224 28234 28496 28555 28651 29565 29685 29816 30195 30214 30235 30290 31241 31521 31958 32310 32484https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/473/1512?format=asciiGamma-rayRadiodefaultJ/MNRAS/473/1512/table1The AMI 15.7GHz GRB catalogue: GRBs that have been detected or possibly detected with AMIrecnoRecord number assigned by the VizieR team.
