A New 95 GHz Methanol Maser Catalog. I. Data

Abstract: The Purple Mountain Observatory 13.7 m radio telescope has been used to search for 95 GHz (8 0 -7 1 A + ) class I methanol masers toward 1020 Bolocam Galactic Plane Survey (BGPS) sources, leading to 213 detections. We have compared the line width of the methanol and HCO + thermal emission in all of the methanol detections, and on that basis, we find that 205 of the 213 detections are very likely to be masers. This corresponds to an overall detection rate of 95 GHz methanol masers toward our BGPS sample of 20%.… Show more

“…The concentration of class I methanol masers increase to the direction of the Galactic center and decrease at the Galactic anti-center: 77% of detected class I methanol masers have 320 < l < 40 deg. The same is reported in Yang et al (2017c) result of the association of class I methanol masers with Galactic star-formation regions located mainly in the Galactic plane. Position-velocity diagram (see Figure 3) reveals that the most populated in class I methanol maser sites are CMZ (Central Molecular Zone or Nuclear Disk) and Molecular Ring.…”
