ALMAGAL Survey: Analysis of 59 Protostellar Clumps hosting Class II Methanol Masers

Georgina Stroud, Gary Fuller, ALMAGAL Collaboration

The ALMAGAL Survey is a galactic-plane survey of over 1000 massive protostellar clumps, using ALMA. As part of the ALMAGAL project, we are studying the subset of 59 ALMAGAL targets which contain 6.7 GHz class II methanol masers. These masers are believed to trace a particular phase in the evolution of massive protostars. This study aims to identify differences between the clumps that host these masers and clumps with otherwise similar properties which do not contain masers. We will report on analyses of the molecules detected in the clumps, the multiplicity of cores inside each clump, separations of maser locations from core locations, and the kinematics of the cores within the clumps.
