Abstract

The Purple Mountain Observatory 13.7m radio telescope has been used to search for 95GHz (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%. Of the 205 detected masers, 144 (70%) are new discoveries. Combining our results with those of previous 95GHz methanol maser searches, a total of 481 95GHz methanol masers are now known. We have compiled a catalog listing the locations and properties of all known 95GHz methanol masers.
