cds-question@unistra.frmilky-way-galaxyvariable-starsvisible-astronomyWe apply the GC3 stream-finding method to RR Lyrae stars (RRLSs) in the Catalina survey. We find 2 RRLS stream candidates at >4{sigma} confidence and another 12 at >3.5{sigma} confidence over the Galactocentric distance range 4<D/kpc<26. Of these, only two are associated with known globular clusters (NGC 1261 and Arp2). The remainder are candidate 'orphan' streams, consistent with the idea that globular cluster streams are most visible close to dissolution. Our detections are likely a lower bound on the total number of dissolving globulars in the inner galaxy, since many globulars have few RRLSs, while only the brightest streams are visible over the Galactic RRLS background, particularly given the current lack of kinematical information. We make all of our candidate streams publicly available and provide a new galstreamspython library for the footprints of all known streams and overdensities in the Milky Way.2018MNRAS.474.4112Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/474/4112CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/339 : Hot Stuff for One Year (HSOY) (Altmann+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/474/4112https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/474/4112http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/474/4112https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/474/4112https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/474/4112http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/474/4112GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/474/4112/table1 (Detection and geometric properties of the stream candidates detected in GC3 +nGC3 PCMs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/474/4112/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/474/4112/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/474/4112/table1?GETtext/xml+votable180.050000true210.428872.64180.005555555555555556Cone search capability for table J/MNRAS/474/4112/table3 (RRLSs associated with each of the stream candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/474/4112/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/474/4112/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/474/4112/table3?GETtext/xml+votable180.050000true252.78216-18.916710.0055555555555555566/1131 2154 2234 2600 2659 2670 2695 2725 4050 4143 4346 5466 5491 5666 5818 6189 6351 7142 7155 7692 7695 7819 8230 8284 8598 8638 8642 8866 8966 9085 9231 9236 9276 9332 9352 9410 9417 9446 9453 9509 9534 9539 9546 9694 9703 9720 9722 9811 9820 9844 9846 9896 9898 9940 10029 10031 10072 10075 10114 10127 10179 10736 10754 10758 10776-10777 10832 11320 11394 11542 11546 12160 12289 12296 12325-12326 12345 12397 12487 12497 12503 12549 12630 12660 13321 13343 13632 13675 14376 14982 15003 15221-15222 15431 15556 16478 16575 16588 16945 16962 17038 17040 17224 17254 17477 17551 17566 17575 17665 17768 17867 18434 18489 18854 19099 19106 19112 19123 19171 19175 19178 19185 19736 19818 19820 19931 19979 20006 20411 20414 21081 21209 21285 21405 22227 22636 22708 23122 23441 23447 24707 24723-24724 24728 24761 24764 24766 24800 24803 24824 24949 24962 24985 25011 25014 25020 25022 25034 25037 25040-25042 25044 25049 25056 25063 25108 25128 25172 25174 25181 25194 25206 25210 25214 25220-25221 25297 25310 25320 25327-25328 25354-25355 25357 25367 25374 25384 25386 25390 25472 25476 25490 25493 25498 25506 25513 25520 25532 25536 25600 25605 25619 25628 25768 25844-25845 25872 25923 25959 25976 26003 26043 26187 26271 26350 26377 26399 26611 26637 26644 26661 26727 26768 26789 26934 26950 26962 27061 27421 27465 27492-27493 27620 27622 27655 27689 27693 27706 27763 27853 27870 28027 28065 28138 28501 28567 28874 29360 29675 30387 30871 30900 31046 31145 31163 31321 31385 31489 31732 32297 32418 32455 32461 32479 32499 32655 32740 32765-32766 32893 33167 33181 33201 33544 33649 34149 34407 34446 34469 34485 34491 34993 35611 35629 35714 35762 35769 35818 35844-35845 35925 36094 36667 36742 36773 36784 36788 37530 38217 38219 38246-38247 38253 38678 38758 38845 38888-38889 38903 39534 39545 40025 40027 40195 40202 40420 40430 40759 40778 40801 41677 41985 42712 43389 43436 43476 43478 43484-43485 43519 43784 43788 43810 43816-43817 43860-43861 43868 44050 44074 44127 44179 44362 44364 44433 44450 44554 44610 44621 44672 44687 44703 44709 44718 44722 44757-44758 44927 44954 45023 45619 45675 45741 45803 45896 45977 45997 46002 46009 46078 46084 46148 46163 46199 46206 46384 46639 46817 46831 46840 46842-46843 46859 46982 47105 47114 47123 47136 47139 47147 47197 47263 47283 47313 47373 47402 47404 47406 47479 47481-47483 47487 47492-47493 47561 47595 47608 47612 47614 47890 47903 47910 47916 47921 47926 47940 47945 47950 47956 47960 47962-47963 47965 47972 47984-47985 47990-47991 48132 48139 48160 48186 48209 48264 48291 48293 48299 48309 48315 48362 48384 48394 48404 48407 48570 48596 48598 48600 48613-48614 48621 48660-48662 48669 48706-48707 48712 48730 48750-48751 48754 48759 48763 48796 48812 48839 48846 48886 48916 48921 48965-48966 48972 48985 48993 49046 49056 49060 49068 49094 49109 49118 49136 49140 49149https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/474/4112?format=asciiOpticaldefaultJ/MNRAS/474/4112/table1Detection and geometric properties of the stream candidates detected in GC3 +nGC3 PCMsComCommentsmeta.notechar_RA.icrsRight ascension (ICRS) (computed by VizieR, not part of the original data.
