High-mass Star Formation in the Near and Far 3 kpc Arms
journal contribution
posted on 2023-05-16, 23:53 authored by Green, JA, McClure-Griffiths, NM, Caswell, JL, Simon EllingsenSimon Ellingsen, Fuller, GA, Quinn, L, Voronkov, MAWe report on the presence of 6.7 GHz methanol masers, known tracers of high-mass star formation, in the 3 kpc arms of the inner Galaxy. We present 49 detections from the Methanol Multibeam Survey, the largest Galactic plane survey for 6.7 GHz methanol masers, which coincide in longitude, latitude, and velocity with the recently discovered far-side 3 kpc arm and the well-known near-side 3 kpc arm. The presence of these masers is significant evidence for high-mass star formation actively occurring in both 3 kpc arms.
