cds-question@unistra.fryoung-stellar-objectsinfrared-sourcesastrophysical-masersradio-astronomyThe Red MSX Source (RMS) survey has identified a sample of ~1200 massive young stellar objects (MYSOs), compact and ultra-compact HII regions from a sample of ~2000 MSX and Two Micron All Sky Survey (2MASS) colour-selected sources. We have used the 100-m Green Bank Telescope to search for 22-24GHz water maser and ammonia (1,1), (2,2) and (3,3) emission towards ~600 RMS sources located within the northern Galactic plane. We have identified 308 H_2_O masers which corresponds to an overall detection rate of ~50 per cent. We find no significant difference in the detection rate for HII regions and MYSOs which would suggest that the conditions required to produce maser emission are equally likely in both phases. Comparing the detection rates as a function of luminosity, we find the H_2_O detection rate has a positive dependence on the source luminosity, with the detection rate increasing with increasing luminosity.2011MNRAS.418.1689Uhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/418/1689CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/525/A149 : Red MSX Survey: bolometric fluxes of YSOs (Mottram+, 2010)J/MNRAS/410/1237 : Red MSX survey (RMS) massive young stars (Urquhart+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/418/1689https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/418/1689http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/418/1689https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/418/1689https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/418/1689http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/418/1689GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/418/1689/table2 (MSX names, source types, positions, temperatures, column density and intensities, velocities and line widths of the three ammonia transitions for 591 sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/418/1689/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/418/1689/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/418/1689/table2?GETtext/xml+votable180.050000true270.0945-18.86890.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/MNRAS/418/16895/3588 3660 3672 7275 7278 7376-7377 7383 7564 7578 7605 7651 7654 7679 6/1329 1340 1344 1412 1470 1781 1848 1925 1927-1928 1930 1963 3005 3023 3031 3039 3052 3071 3157 3175 3184 3195 3198 3268 3271 3290 3302 3309 3311 3320 3338 3606 3628 3630 3649 3715 3727-3730 3738 3747 12970-12971 12974-12975 13050 14014 14063 14241 14255 14267 14278 14280 14282 14287 14304 14307-14309 14311-14312 14314-14315 14317 14321 14356 14358 14365 14409 14411 14430 14452 14594 14603-14606 14611 14616 14618 14621-14622 14624-14625 14630 14647 14652 14654-14655 14663-14664 14666-14667 14670-14671 14681-14683 14685 14692-14693 14696-14697 14700 14704 14706 14709 14711 14713 14716 15368 15370 15374 15385 15408-15409 15414 15428 15430 15434-15435 15448-15449 15452 15455-15456 15468 15473 15476-15477 15621 15624 15626-15627 15629 15642 15649 15681-15682 15696 20831 21542 21639 21643 21645 21671 21689 24457 24476 24493 24496 24507 24515 24554 29070 29091-29092 29094-29095 29097 29116 29118 29160 29440 29461 29463 29469 29513 29517 29522 29529 30216 30218-30219 30222 30240-30241 30243-30245 30262-30263 30266-30269 30318-30319 30328 30330 30341 30343 30348 30359 30405 30416-30417 30419 30592 30594-30595 30598 30600 30621-30622 30624-30625 30640 30644 30690-30692 30694-30695 30701 30707 30710 30712 30714-30715 39899 40612https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/418/1689?format=asciiInfraredRadiodefaultJ/MNRAS/418/1689/table2MSX names, source types, positions, temperatures, column density and intensities, velocities and line widths of the three ammonia transitions for 591 sourcesplotimages of NH_3_ spectrameta.ref.urlcharH2O[y/n] H2O maser detectedmeta.codecharrecnoRecord number assigned by the VizieR team.
