VLBI with ALMA in the field of maser studies

Maser lines from species such as SiO, HCN, water, methanol and atomic hydrogen lie in the ALMA Bands. There are several reasons to study masers in the mm/submm in addition to study at longer wavelengths. These include higher angular resolution, the ability to potentially trace out different parts of targets and the possibility to probe regions for which emission from other maser transitions could be obscured. In this talk, I will discuss the implications of VLBI with ALMA for masers in evolved stars, star-forming regions, and the circumnuclear regions of AGN.
