cds-question@unistra.frgalaxy-clustersx-ray-sourcesUnderstanding baryonic physics at the galaxy-group level is a prerequisite for cosmological studies of the large-scale structure. One poorly understood aspect of galaxy groups is related to the properties of their hot intragroup medium. The well-studied X-ray groups have strong cool cores by which they were selected, so expanding the selection of groups is currently an important avenue in uncovering the diversity within the galaxy group population. We present a new all-sky catalogue of X-ray-detected groups (AXES-2MRS) based on the identification of large X-ray sources found in the ROSAT All-Sky Survey (RASS) with the Two Micron Redshift Survey (2MRS) Bayesian Group Catalogue. We studied the basic properties of these galaxy groups to gain insights into the effect of different group selections on the properties. In addition to X-ray luminosity from shallow survey data of RASS, we obtained detailed X-ray properties of the groups by matching the AXES-2MRS catalogue to archival X-ray observations by XMM-Newton and complemented this by adding the published XMM-Newton results on galaxy clusters in our catalogue. We analysed temperature and density to the lowest overdensity accessible by the data, obtaining hydrostatic mass estimates at a uniform overdensity of 10000 times the critical, and comparing them to the velocity dispersions of the groups. We explored the relationship between X-ray and optical properties of AXES-2MRS groups through the sigma_v_-L_X_, sigma_v-kT, kT-L_X_, {sigma}_v-M_, and c_200_-L_X_ scaling relations. We find a large spread in the central mass M_10000_, measured by XMM-Newton, to virial mass M_200_, inferred by the velocity dispersion, ratios for galaxy groups. This can either indicate that large non-thermal pressure of galaxy groups affects our X-ray mass measurements or the effect of a diversity of halo concentrations on the X-ray properties of galaxy groups. Previous catalogues based on detecting the peak of the X-ray emission preferentially sample the high-concentration groups. In contrast, our new catalogue uncovered many low-concentration groups, completely revising our understanding of X-ray groups.2024A&A...690A.212Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/690/A212CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/618/A81 : Bayesian group finder applied to the 2MRS data (Tempel+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/690/A212https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/690/A212http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/690/A212https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/690/A212https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/690/A212http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/690/A212GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/690/A212/axes2mrs (AXES-2MRS catalogue (table C1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/690/A212/axes2mrs?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/690/A212/axes2mrs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/690/A212/axes2mrs?GETtext/xml+votable180.050000true49.9816641.497870.0055555555555555566/50 82 87 148 225 227 242 306 377 659 721 751 822 929 986 1200 1255 1526 1579-1580 1598 1601 1647 1667 1671 1684 1691 1701 1704 1707-1708 1727 1845 2065 2169 2186 2215 2217 2227 2231 2251 2264 2332 2341 2353 2375 2378 2387-2388 2394-2395 2409 2414 2432 2830 2966 3075 3082-3083 3105 3116 3130 3516 3703 4110 4188 4373 4468 4488 4491 4540 4616 4777 4804 4928 4966 4990 4992 5030 5394 5423 5558 5597 5616 5622 5772 5865 5894 5982 6000 6057 6087 6097 6101 6138 6177 6213 6304 6340 6639 6963 6999 7026 7042 7064 7254 7355 7385 7413 7613 7681 7684 7716 7923 7925 8048 8066 8085 8173 8179 8196 8225 8264 8266 8268 8271 8351 8419 8442 8477 8514 8520 8526 8648 8735 8793 8919 8939 9019 9026 9264 9285 9287 9305 9348 9368 9371 9443 9464 9468 9471 9526 9672 9827 9946 9987 10095 10132 10182 10196 10207 10220 10257 10342 10379 10438-10439 10442 10456 10472 10475 10560 10904 10923 10979 11015 11101 11182 11263 11301 11384 11389 11438 11543 11568 11612 11626 11633 11696 11989 12025 12121 12153 12210 12217 12241 13100 13430 13512 13543 13550 13564 13720 13760 13894 14024 14135 14228 14879 14893 14939 14979 15085 15112 15174 15243 15562 15933 16112 16454 16492 16543 16619 17435 17472 17509 17513 17522 17662 17673 17745 17754 17784 17810 17982 17998 18001 18009 18016 18035 18064 18071 18148 18168 18184 18241 18324 18411 18742 18757 18939 18941 19130 19269 19321 19432 19501 19516 19608 19626 19900 19993 20021 20029 20078 20112 20124 20221 20286 20308 20325 20355 20392 20432 20481 20511 20527 20642 20644 20669 20706 20742 21016 21036 21039 21133 21139 21142 21256 21823 21977 22374 22545 22577 22610 22644 22746 22773 22830 22912 22936 22939 22962 23027 23041 23077 23169 23226 23306 24053 24160 24633 24683 24848 24906 24912 24943 24951 25042 25054 25498 25593 25610 25633 25687 25762 25769 25981-25982 26128 26148 26313 26349 26432 26474 26563 26596 26710 26733 26874 26884 27060 27079 27160 27224 27255 27471 27486 27606 27652 27672 27714 27719 27736 27803 28047 28075 28090 28151-28152 28234 28249 28301 28360 28377 28414-28415 28441 28471 28476 28494 28517 28597 28758 29234 29625 29908 31080 31111 31219 31256 31305 31465 31998 32147 32175 32183 32186 32602 32606 32660 32662 32683 32693 32746 33034 33095 33242 33264 33605 33624 33638 33649 33666 33828 33869 33894 33956 33968 34025 34207-34208 34229 34260 34334 34495 34535-34536 34694 34961 34973 35052 35055 35360 35719 35987 36150 36152 36247 36299 36669 37294 37388 37513 37538 37567 37771 37802 38096 38129 38308 38364 38515 38704 38820 38842 38853 38912 38916 38920 38922 38975 39040 39048 39077 39139-39140 39558 39562 39613 39627 39658 39715 39724-39725 39912 40214 40293 40316 40337 40340 40402 40404 40442 40466 40495 40538 40774 40809 41240 41279 41326 41423 41510 41923 41929 42640 43078 43259 43412 43451 43503 43603 43621 43627 43644 43649 43677 43702 43806 43830 43835-43838 43849 43877 43925 43939 43941 43948 43968 43971 43977 44000 44005 44247 44550 44554 44585 44613 44698 45227 45389 45636 45754 45756 45852 45984 45997 46020 46077 46212 46484 46495 46526 46608 46615 46756 47120 47375 47466 47541 47951 48064 48128 48132 48134 48311 48323 48344 48349 48440 48717 48945 48950https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/690/A212?format=asciiX-raydefaultJ/A+A/690/A212/axes2mrsAXES-2MRS catalogue (table C1)NmembNumber of spectroscopic members in 2MRS group catalogue (NMEM)meta.numberintNmembClean?
