cds-question@unistra.frglobular-star-clustersgalaxiesvisible-astronomygalaxy-classification-systemsgalaxy-kinematicsWe describe the structural and kinematic properties of the first compact stellar systems discovered by the Archive of Intermediate Mass Stellar Systems project. These spectroscopically confirmed objects have sizes (~6<R_e_[pc]<500) and masses (~2x10^6^<M*/M_{sun}_<6x10^9^) spanning the range of massive globular clusters, ultracompact dwarfs (UCDs) and compact elliptical galaxies (cEs), completely filling the gap between star clusters and galaxies. Several objects are close analogues to the prototypical cE, M32. These objects, which are more massive than previously discovered UCDs of the same size, further call into question the existence of a tight mass-size trend for compact stellar systems, while simultaneously strengthening the case for a universal 'zone of avoidance' for dynamically hot stellar systems in the mass-size plane. Overall, we argue that there are two classes of compact stellar systems (1) massive star clusters and (2) a population closely related to galaxies. Our data provide indications for a further division of the galaxy-type UCD/cE population into two groups, one population that we associate with objects formed by the stripping of nucleated dwarf galaxies, and a second population that formed through the stripping of bulged galaxies or are lower mass analogues of classical ellipticals. We find compact stellar systems around galaxies in low- to high-density environments, demonstrating that the physical processes responsible for forming them do not only operate in the densest clusters.2014MNRAS.443.1151Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/443/1151CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/421/1485 : NGC 3923 globular clusters (Norris+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/443/1151https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/443/1151http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/443/1151https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/443/1151https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/443/1151http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/443/1151GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/443/1151/tablea1 (Catalogue of Compact Stellar Systems (CSS) and comparison sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/443/1151/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/443/1151/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/443/1151/tablea1?GETtext/xml+votable180.050000true14.4536811130.352448060.0055555555555555565/4581 6930 6935 6941 6978 8633 6/50 619 664 697 1133 1701 1707 2110 2142 2145 2214 2216 2234 2272 2297 2374 2432 2565 2572-2573 2604 2611 2621-2623 2628 2666 2668 2676 2704 2708-2710 2746 2755 2758 2767 2789 2830 2852 3950 4378 4410 4419 4439 4447 4565 4807 4829 4869 4930 4989-4990 5021 5075 5125 5134 5182 5196 5288 5398 5429 5474 5558 5599 5608 5623 5745 5939 5975 5999 6021 6047 6087 6090 6093 6097 6103 6162 6389 6623 7110 7214 7265 7287 7355 7374 7385 7416 7424 7460 7560 7584 7597 8173 8193 8195-8197 8208 8228 8264 8266 8533 8745 9186 9436 9666 10008 10153 10183 10203 10308 10321 10336 10379 10444 10454 10501 10523 10551 10628 10637 10714 10720 10739 10769 10901 10924 10980 11026 11246 11253 11263 11418 11435 11443 11448 11457 11691 11776 11791 11800 11824 12018 12025 12425 12531 13336 13401 13505 13655 14149 14489 15056 15204 16459 16647 16898 17121 17183 17229 17472 17492 17605 17612 17744-17745 17761 18002 18011 18184 18209 18241 18269 18411 18748 18755 18766 18926 18935 19091 19442 19506 19990 20014 20101 20262 20277 20353 20355 20416 20437 20440 21017 22577 22740 22746 22826 22914 23177-23178 24732-24733 24843 24912 25083 25533 25571 25768 25873 25893 25907 25979 26055 26065 26068 26125 26128 26149 26157 26166 26173 26210 26285 26307 26313 26316-26317 26361-26362 26487 26542 26803 26983 27000 27079 27135 27186 27199 27207 27237 27255 27367 27458 27480 27515 27518 27580 27595 27604-27606 27669 27671 27712-27714 27718-27719 27728 27730 27734-27736 27738-27739 27748 27755-27756 27758 27763 27769 27771-27774 27802 27857 27859 27861-27862 27904-27905 27907-27908 27910 27919 27931 27936 27938 27941 27944-27946 27948-27949 27981 27986 28032-28034 28036-28038 28044-28045 28067 28136 28141-28142 28200 28221 28264 28300 28311 28360-28362 28491 28495 28515 28524 28538 28577 28601 28653 28705 28741 28769 28778 28882 28962 28973 29187 29216 29231 29267 29294 29318 29377 29636-29637 29816 29870 30321 30378 30769 30998 31019 31043 31115 31398 31404 31417-31418 31453-31454 31469 31624 31692 31723 31795 32083 32168 32482 32539 33321 33330 33635 33954 34242 34317 34334 34492-34493 35482 35536 35720 35908 35969 36152 36156 36247 36623 36785 36819 36831 37294 38347 38465 38704 39100 39642 39860 40294 40952 41011 41257 41304 42314 42320 42700 42761 42841 42955 42990 43125 43227 43262 43627 43828 43849 44086 44220 44427 45423 46043 46568 47078 47383 47620 47777 47825 47866 47916 47971 48035 48444 48698 48942 48952https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/443/1151?format=asciiOpticaldefaultJ/MNRAS/443/1151/tablea1Catalogue of Compact Stellar Systems (CSS) and comparison sampleSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
