cds-question@unistra.frastrophysical-masersradio-astronomyinfrared-photometryradio-spectroscopyWe performed a systematic 6.7GHz Class II methanol maser survey using the Shanghai Tianma Radio Telescope toward targets selected from the all-sky Wide-Field Infrared Survey Explorer (WISE) point catalog. In this paper, we report the results from the survey of those at high Galactic latitudes, i.e., |b|>2{deg}. Of 1473 selected WISE point sources at high latitude, 17 point positions that were actually associated with 12 sources were detected with maser emission, reflecting the rarity (1%-2%) of methanol masers in the region away from the Galactic plane. Out of the 12 sources, 3 are detected for the first time. The spectral energy distribution at infrared bands shows that these new detected masers occur in the massive star-forming regions. Compared to previous detections, the methanol maser changes significantly in both spectral profiles and flux densities. The infrared WISE images show that almost all of these masers are located in the positions of the bright WISE point sources. Compared to the methanol masers at the Galactic plane, these high-latitude methanol masers provide good tracers for investigating the physics and kinematics around massive young stellar objects, because they are believed to be less affected by the surrounding cluster environment.2017ApJ...846..160Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/846/160CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)VIII/96 : 6-GHz methanol multibeam maser catalogue (Caswell+, 2010-12)J/A+A/291/943 : Protostellar cores (Ossenkopf+, 1994)J/A+AS/110/81 : Methanol masers towards IRAS sources (van der Walt+ 1995)J/MNRAS/291/261 : Methanol maser of IRAS-selected sources (Walsh+ 1997)J/MNRAS/301/640 : Ultracompact H II regions studies.
