cds-question@unistra.frgalaxy-clustersredshiftedIn an earlier paper we inferred, from the distribution of galaxy redshifts in three small fields ~30{deg} apart, the existence of a 10^6^Mpc^3^ void in the distribution of galaxies in the constellation of Bootes. In this paper, we describe a redshift survey undertaken to test that hypothesis. Galaxies were selected by eye from 283 small fields distributed between the three original fields, and redshifts were measured for 239 of them. We confirm the existence of a large, roughly spherical void, of radius 62Mpc, centered at {alpha}=14h50, {delta}=+46{deg}, v=15500km/s. The low density of this region is of high statistical significance and does not appear easily reconcilable with any of the popular models for the growth of structure in the universe. This void does contain some unusual galaxies characterized by strong, high-excitation emission spectra, but not in sufficient numbers to compensate for the absence of more usual objects.1987ApJ...314..493Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/314/493CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/314/493https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/314/493http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/314/493https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/314/493https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/314/493http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/314/493GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/314/493/table1 (Survey fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/314/493/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/314/493/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/314/493/table1?GETtext/xml+votable180.050000true205.2248929.14760.005555555555555556Cone search capability for table J/ApJ/314/493/table2 (The galaxy sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/314/493/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/314/493/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/314/493/table2?GETtext/xml+votable180.050000true208.3330340.366070.0055555555555555566/9082 9113 9115 9125 9129 9131 9133 9145 9147 9148 9150 9164 9166 9172 9178 9180 9184 9186 9190 9194 9196 9200 9204 9207 9208 9209 9210 9215 9469 9759 9768 9775 9779 9785 9802 9806 9811 9813 9817 9823 9826 9830 9834 9836 9843 9853 9857 9859 9863 9867 9869 9870 9876 9878 9880 9886 9887 9888 9889 9893 9894 9895 9896 9897 9898 9900 9903 9904 9908 9910 9911 9912 9913 9914 9919 9922 9924 9926 9928 9934 9939 9952 9954 9961 9962 9963 9964 9968 9978 10319 10323 10327 10331 10333 10339 10343 10349 10351 10353 10357 10361 10365 10449 10453 10455 10497 10501 10505 10509 10511 10513 10518 10523 10526 10529 10531 10535 10537 10539 10543 10545 10547 10553 10557 10559 10562 10564 10567 10568 10571 10572 10573 10574 10577 10578 10579 10580 10585 10586 10587 10588 10591 10592 10595 10597 10598 10599 10600 10601 10605 10606 10607 10608 10611 10614 10616 10617 10618 10622 10627 10631 10635 10637 10641 10645 10647 10649 10651 10655 10661 10675 10677 10685 10688 10690 10692 10695 10700 10701 10702 10705 10706 10707 10708 10713 10714 10715 10716 10718 10726 10734 10736 10743 10744 10746 10751 11093 11265 11266 11267 11268 11269 11272 11275 11276 11277 11278 11281 11282 11283 11285 11288 11291 11293 11295 11296 11297 11298 11301 11302 11303 11304 11305 11306 11308 11311 11312 11315 11319 11320 11321 11322 11325 11327 11330 11331 11336 11339 11340 11352 11360 11362 11366 11370 11384 11391 11393 11394 11395 11396 11397 11400 11403 11404 11405 11409 11410 11411 11412 11419 11422 11425 11429 11431 11433 11435 11439 11446 11452 11458 11460 11464 11470 11474 11485 11488 11490 11494 11496 11498 11500 11505 11511 11515 11689 11779 11781 11789 11796 11798 11806 11842 11844 11848 11852 11854 11861 11867 11872 11878 11889 11893 11897 12035https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/314/493?format=asciiOpticaldefaultJ/ApJ/314/493/table1Survey fieldsFieldField numbermeta.id;obs.fieldintprimaryrecnoRecord number assigned by the VizieR team.
