cds-question@unistra.frSeveral large structures, including the Sloan Great Wall, the Huge Large Quasar Group, and a large gamma-ray burst cluster referred to as the Hercules-Corona Borealis Great Wall, appear to exceed the maximum structural size predicted by Universal inflationary models. The existence of very large structures such as these might necessitate cosmological model modifications. Gamma-ray bursts are the most luminous sources found in nature. They are associated with the stellar endpoints of massive stars and are found in and near distant galaxies. Since they are viable indicators of the dense part of the Universe containing normal matter, the spatial distribution of gamma-ray bursts can serve as tracers of Universal large-scale structure. An increased sample size of gamma-ray bursts with known redshift provides us with the opportunity to validate or invalidate the existence of the Hercules-Corona Borealis Great Wall. Nearest-neighbour tests are used to search the larger sample for evidence of clustering and a bootstrap point-radius method is used to estimate the angular cluster size. The potential influence of angular sampling biasing is studied to determine the viability of the results. The larger gamma-ray burst database further supports the existence of a statistically significant gamma-ray burst cluster at 1.6<=z<2.1 with an estimated angular size of 2000-3000Mpc. Although small number statistics limit our angular resolution and do not rule out the existence of adjacent and/or line-of-sight smaller structures, these structures must still clump together in order for us to see the large gamma-ray burst cluster detected here. This cluster provides support for the existence of very large-scale universal heterogeneities.2015A&A...584A..48Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/584/A48CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.astro.caltech.edu/grbox/grbox.php : Gamma-Ray Burst Online Indexhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/584/A48https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/584/A48http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/584/A48https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/584/A48https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/584/A48http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/584/A48GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/584/A48/tablea1 (ID, duration, coordinates, and redshift of the 357 GRBs as were published at http://www.astro.caltech.edu/grbox/grbox.php)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/584/A48/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/584/A48/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/584/A48/tablea1?GETtext/xml+votable180.050000true210.6668832.170640.0055555555555555566/186 207 228 314 393 500 503 557 585 646 699 908 918 944 2044 2315 2357 2375 2538 2735 2948 3111 3536 3586 3935 4312 4323 4341 4371 4397 4449-4450 4485 4955 5051 5061 5376 5455 5493 5625 5633 5726 5840 5941 5987 6102 6141 6258 6261 6404 6445 6448 6729 7182 7227 7518 7532 7650 8074 8103 8318 8459 8641 8669 8733 8761 8798 8932 9022 9100 9321 9363 9370 9431 9576 9682 9750 9910 9989 9998 10080 10094 10135 10166 10335 10400 10407 10447 10519 10589 10602 10666 10704 10723 10762 10852 10912 11008 11220 11649 11657 11673 11756 11822 11905 12020 12134 12438 12597 13312 13331 13694 13701 13720 13779 13924 14259 14892 14977 15004 15054 15214 15246 15295 15348 15530 15915 16057 16282 16489 16524 16546 16661 16991 17038 17316 17406 17411 17453 17561 17703 17721 17733 17749 17758 17814 17911 18030 18494 18681 18777 18911 18978 19049 19164 19168 19194 19293 19519 19731 19864-19865 19890 19911 20030 20053 20177 20191 20263 20346 20360 20372 20401 20460 20655 20753 21082 21284 21439 21498 21595 21688 21766 21962 22008 22129 22422 22559 22580 22619 22916 23138 23413 24072 24779 24993 25146 25148 25174 25192 25248 25452 25761 25901 25946 26036 26365 26441 26503 26671 27085 27238 27289 27566 27572 27841 27906 27933 27961-27962 27983 28058 28063 28187 28234 28344 28497 28546 28555 28930 29231 29816 30088 30195 30557 31185 31281 31385 31494 31521 31583 31607 31667 31700 31934 32110 32239 32310 32646 32713 32790 33004 33050 33265 33278 33525 33617 33679 33735 33813 34147 34364 34435 34440 34465 34699 34788 34949 35045 35088 35227 35330 35393 35427 35566 35569 35633 35844 36066 36074 36292 36297 36361 36460 36528 37007 37123 37324 37459 37505 37628 38280 38926 39008 39076 39327 39427 39594 39993 40249 40433 40482 40778 41020 41095 42545 42901 42952 43193 43853 44021-44022 44212 44630 44857 45008 45180 45205 45347 45361 45401 45409 45510 45777 45828 45836 45938 46022 46218 46250 46365 46510 46517 46594 46789 47027 47031 47136 47148 47162 47217 47251 47436 47454 47459 47620 47991 48007 48054 48189 48371 48447 48458 48666 48804 49004https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/584/A48?format=asciiGamma-rayOpticaldefaultJ/A+A/584/A48/tablea1ID, duration, coordinates, and redshift of the 357 GRBs as were published at http://www.astro.caltech.edu/grbox/grbox.phprecnoRecord number assigned by the VizieR team.
