cds-question@unistra.frastrophysical-masersradio-astronomyinterstellar-mediumWe have observed a sample of 288 molecular outflow sources including 123 high-mass and 165 low-mass sources in order to search for class I methanol masers at the 95GHz transition and to investigate the relationship between outflow characteristics and class I methanol maser emission with the Purple Mountain Observatory 13.7m radio telescope. Our survey detected 62 sources with 95GHz methanol masers above a 3{sigma} detection limit, which includes 47 high-mass sources and 15 low-mass sources. Therefore, the detection rate is 38% for high-mass outflow sources and 9% for low-mass outflow sources, suggesting that class I methanol masers are relatively easily excited in high-mass sources. There are 37 newly detected 95GHz methanol masers (including 27 high-mass and 10 low-mass sources), 19 of which are newly identified (i.e., first identification) class I methanol masers (including 13 high-mass and 6 low-mass sources). A statistical analysis of the distributions of maser detections with the outflow parameters reveals that the maser detection efficiency increases with the outflow properties (e.g., mass, momentum, kinetic energy, mechanical luminosity of outflows, etc.). Systematic investigations of the relationships between the intrinsic luminosity of methanol masers and the outflow properties (including mass, momentum, kinetic energy, bolometric luminosity, and mass-loss rate of the central stellar sources) indicate a positive correlation. This further supports the theory that class I methanol masers are collisionally pumped and associated with shocks when outflows interact with the surrounding ambient medium.2013ApJ...763....2Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/763/2CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/96 : 6-GHz methanol multibeam maser catalogue (Caswell+, 2010-12)J/AZh/89/611 : Class I methanol maser catalog (Bayandina+, 2012)J/ApJS/200/5 : 95GHz class I methanol maser survey (Chen+, 2012)J/ApJS/196/9 : 95GHz methanol maser survey toward GLIMPSE EGOs (Chen+, 2011)J/ApJ/702/1615 : CH_3_OH maser survey of EGOs (Cyganowski+, 2009)J/other/PASA/26.454 : Precise positions of methanol masers (Caswell, 2009)J/AJ/136/2391 : GLIMPSE Extended Green Objects catalog (Cyganowski+, 2008)J/AZh/84/839 : Methanol emission of isolated maser (Larionov+, 2007)J/AZh/84/579 : Catalog of Class I methanol masers (Val'tts+, 2007)J/ApJ/656/255 : Arecibo methanol maser Survey (Pandian+, 2007)J/MNRAS/359/1498 : Class I and class II methanol masers (Ellingsen+, 2005)J/A+A/432/737 : General Cat. of 6.7GHz Methanol Masers (Pestalozzi+, 2005)J/A+A/426/503 : Cat. of high velocity molecular outflows (Update) (Wu+ 2004)J/ApJS/155/149 : CH_3_OH 7_0_-6_1_ A^+^ maser sources (Kurtz+, 2004)J/A+A/403/1095 : 6.7GHz methanol masers survey of YSO (Minier+, 2003)J/A+A/314/615 : Maps of the 36 GHz methanol emission (Liechti+, 1996)J/AZh/72/22 : A 95 GHz Survey of Methanol Masers (Valtts+, 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/763/2https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/763/2http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/763/2https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/763/2https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/763/2http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/763/2GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/763/2/masers (Combined table from original tables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/763/2/masers?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/763/2/masers?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/763/2/masers?GETtext/xml+votable180.050000true274.800417-20.7905560.005555555555555556Cone search capability for table J/ApJ/763/2/table6 (Sources that have no 95GHz methanol masers detected)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/763/2/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/763/2/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/763/2/table6?GETtext/xml+votable180.050000true248.622083-15.7836110.0055555555555555566/68 69 70 110 113 190 227 529 531 862 2973 2996 3011 3061 3290 12294 12338 12462 12490 12491 12606 12694 12711 12714 12749 12751 12754 12809 12818 12824 12829 12833 12853 12872 12874 12876 12889 12898 12912 13025 13050 13056 13073 13314 13316 14002 14287 14307 14309 14314 14315 14317 14353 14355 14372 14622 14624 14647 14655 14689 14692 14697 14704 15479 15667 15759 18885 19144 19168 19193 19198 19207 19218 19241 19316 19321 19344 19358 19362 19370 19377 19393 19436 19437 19443 19565 19645 19646 19705 19757 19781 19847 19850 19852 19981 19983 19998 20007 20008 20859 21303 21425 21428 21430 21435 21436 21439 21456 21458 21643 21646 22038 22045 22243 22555 22797 22804 22805 22854 22855 22860 22866 22873 22876 22954 22955 22959 23030 23161 23278 23292 23293 23296 23298 23328 23466 23530 23533 23549 23562 23563 23601 23636 23637 23692 23697 23704 23728 23734 23739 23795 23810 23969 24071 24113 24158 24189 24325 24507 24554 29070 29092 29094 29096 29154 29504 29509 29556 29653 30119 30137 30141 30143 30176 30234 30241 30319 30341 30355 30366 30420 30481 30519 30551 30552 30594 30595 30618 30621 30622 30623 30644 30714 30715 30716 30719 30733 30821 32083 44374https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/763/2?format=asciiRadiodefaultJ/ApJ/763/2/masersCombined table from original tablesrecnoRecord number assigned by the VizieR team.
