cds-question@unistra.frgalaxiesgalaxy-clustersWe note that nearby galaxies having high negative peculiar velocities are distributed over the sky very inhomogeneously. A part of this anisotropy is caused by the "Local Velocity Anomaly," i.e., by the bulk motion of nearby galaxies away from the Local Void. However, half of the fast-flying objects reside within a small region [RA=11.5h-13.0h, DE=+20{deg}-40{deg}] known as the Coma I cloud. According to Makarov & Karachentsev, this complex contains 8 groups, 5 triplets, 10 pairs, and 83 single galaxies with a total mass of 4.7x10^13^M_{sun}_. We use 122 galaxies in the Coma I region with known distances and radial velocities V_LG_<3000km/s to draw the Hubble relation for them. The Hubble diagram shows a Z-shaped effect of infall with an amplitude of +200km/s on the nearby side and -700km/s on the back side. This phenomenon can be understood as the galaxy infall toward a dark attractor with a mass of ~2x10^14^M_{sun}_ situated at a distance of 15 Mpc from us. The existence of a large void between the Coma and Virgo clusters also probably affects the Hubble flow around the Coma I.2011ApJ...743..123Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/743/123CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/412/2498 : Galaxy groups and clouds in local universe (Makarov+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/743/123https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/743/123http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/743/123https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/743/123https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/743/123http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/743/123GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/743/123/table1 (List of 36 Galaxies with V_LG_<600km/s and D>12Mpc (Outside the Virgo Cluster Core))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/743/123/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/743/123/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/743/123/table1?GETtext/xml+votable180.050000true54.878333-18.6880560.005555555555555556Cone search capability for table J/ApJ/743/123/table2 (MK-Groups with V_LG_<3000km/s within RA=[11.5h,13.0h], DE=[+20{deg},+40{deg}])https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/743/123/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/743/123/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/743/123/table2?GETtext/xml+votable180.050000true177.28958327.0219440.005555555555555556Cone search capability for table J/ApJ/743/123/table3 (MK-Triplets and Pairs with V_LG_<3000km/s within RA=[11.5h,13.0h], DE=[+20{deg},+40{deg}])https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/743/123/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/743/123/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/743/123/table3?GETtext/xml+votable180.050000true173.95833335.3352780.005555555555555556Cone search capability for table J/ApJ/743/123/table4 (Field Galaxies within RA=[11.5h,13.0h], DE=[+20{deg},+40{deg}], V_LG_<3000km/s)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/743/123/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/743/123/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/743/123/table4?GETtext/xml+votable180.050000true172.54708335.8688890.0055555555555555565/1349 7129 7159 6/4983 5061 5116 5440 5448 5451 5456 5708 7242 10402 10755 10757 10758 10761 10762 10767 10769 10771 10774 10784 10785 10787 10789 10793 10798 10799 10800 10808 10809 10810 10814 10881 10883 10888 10889 10892 10896 10897 10898 10912 10914 10921 10923 10924 10925 10934 10998 20400 27375 27465 28003 28015 28060 28076 28077 28081 28087 28091 28097 28100 28123 28126 28141 28142 28145 28147 28149 28151 28154 28156 28200 28247 28283 28287 28375 28416 28435 28438 28444 28451 28461 28463 28468 28471 28476 28477 28479 28483 28486 28487 28489 28491 28493 28494 28495 28496 28498 28502 28505 28508 28510 28511 28513 28515 28521 28523 28524 28526 28528 28529 28531 28535 28538 28540 28543 28557 28574 28577 28593 28595 28596 28598 28601 28603 28604 28607 28608 28610 28612 28620 28630 28631 28643 28644 28650 28651 28653 28659 28666 28670 33271 33277 36247 38843 40177 40323 403588.650015785639275e-20 9.710690472292815e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/743/123?format=asciiOpticaldefaultJ/ApJ/743/123/table1List of 36 Galaxies with V_LG_<600km/s and D>12Mpc (Outside the Virgo Cluster Core)SimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
