TL;DR
This study uses high-resolution VLA observations to identify and catalog 44 GHz methanol maser sources in three massive star-forming regions, expanding the understanding of maser distributions in such environments.
Contribution
It provides detailed VLA observations of methanol masers in NGC 6334F, G8.67-0.36, and M17, completing a larger survey and confirming maser presence in these regions.
Findings
Detected 8 maser components in NGC 6334F
Detected 12 maser components in G8.67-0.36
Detected 1 maser component in M17
Abstract
We present Very Large Array observations of the 7_0-6_1 A^+ methanol maser transition at 44 GHz towards NGC 6334F, G8.67-0.36, and M17. These arcsecond resolution observations complete a previous, larger VLA survey of this maser transition in high-mass star-forming regions reported by Kurtz et al. We confirm the presence of 44 GHz methanol maser emission in all three sources, detecting eight distinct maser components in NGC 6334F, twelve components in G8.67-0.36 and one in M17.
