cds-question@unistra.frgalaxy-clustersredshiftedThe halo assembly bias, a phenomenon referring to dependencies of the large-scale bias of a dark matter halo other than its mass, is a fundamental property of the standard cosmological model. First discovered in 2005 from the Millennium Run simulation, it has been proven very difficult to be detected observationally, with only a few convincing claims of detection so far. The main obstacle lies in finding an accurate proxy of the halo formation time. In this study, by utilizing a constrained simulation that can faithfully reproduce the observed structures larger than 2Mpc in the local universe, for a sample of 634 massive clusters at z<=0.12, we found their counterpart halos in the simulation and used the mass growth history of the matched halos to estimate the formation time of the observed clusters. This allowed us to construct a pair of early- and late-forming clusters, with a similar mass as measured via weak gravitational lensing, and large-scale biases differing at the ~3{sigma} level, suggestive of the signature of assembly bias, which is further corroborated by the properties of cluster galaxies, including the brightest cluster galaxy and the spatial distribution and number of member galaxies. Our study paves a way to further detect assembly bias based on cluster samples constructed purely on observed quantities.2022A&A...666A..97Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/666/A97CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/666/A97https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/666/A97http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/666/A97https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/666/A97https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/666/A97http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/666/A97GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/666/A97/table1 (Early-forming clusters of the z_20ex,Mz_ set)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/666/A97/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/666/A97/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/666/A97/table1?GETtext/xml+votable180.050000true257.4468988934.438801110.005555555555555556Cone search capability for table J/A+A/666/A97/table2 (Late-forming clusters of the z_20ex,Mz_ set)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/666/A97/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/666/A97/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/666/A97/table2?GETtext/xml+votable180.050000true227.337401947.6519950.0055555555555555566/4146 4238 4243 4327 4487 4523 4526 4556 4607 4638 4647 4655 4658 4666 4705 4718 4813 4821 4996 5005 5011-5014 5017 5050 5078 5113 5118 5206 5234 5285 5290 5332 5338 5363 5373 5425 5428 5432 5471 5492 5524 5573 5585 5606 5699 5715 5761 5775 5911 5929 5960 5987-5988 5990 5996 6047 6140 6391 6434 6437 6449 6481 6535 7180 7223 7266 7303 7317 7361 7372 8208 8214 8219-8220 8262 8288 8335 8340 8418 8514 8518 8552 8561 8572 8608 8612-8613 8661 8663 8667-8668 8685 8713 8808 8821 8859 8884 8913 8918-8919 8963 8968 9003 9032 9038-9040 9047-9048 9051-9052 9058 9072 9081 9084 9166 9184 9219 9251 9268 9289 9317 9384 9403 9504 9507-9508 9747 9753 10242 10267 10269 10311 10319 10322 10339 10478 10614 10616 10619 10622 10627 10679 10689 10691 10693 10718 10733 10823 10848 10987 11003 11005 11080 11114 11137 11159 11195 11250 11287 11448 11499 11778 11936 22003 22010 22012 25852 25915 25935 26016 26042 26071 26075 26100 26167 26169 26179 26193 26195 26197 26200 26205 26215 26259 26313 26329 26339 26373 26439 26526 26545 26568 26573 26965 27064 27074 27089 27247 27257 27314 27325 27334 27378 27407 27452 27472 27476 27533 27539 27570 27587 27619 27676 27685 27692 27694 27736 27765 27781 27792-27793 27804 27841 27844 27848 27867 27872 27879 27937 27943 27999 28265 28269 28378 28518 28529 28620 31387 31391 31412 31417 31419 31449 31458 31474 31635 31656https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/666/A97?format=asciidefaultJ/A+A/666/A97/table1Early-forming clusters of the z_20ex,Mz_ setRAJ2000Right ascension (J2000)degpos.eq.ra;meta.mainDEJ2000Declination (J2000)degpos.eq.dec;meta.mainzCluster redshiftsrc.redshiftdoublez20Formation redshiftsrc.redshift;pos.heliocentricdoublerecnoRecord number assigned by the VizieR team.
