Star formation is the defining process in the evolution of galaxies.
understanding of star formation has primarily been informed by low-mass
stars in nearby clouds, but these nearby regions do not reflect typical
conditions over the history of the universe. The denser and more crowded
regions that represent our own origins exist within our Galaxy, and ALMA
allows us to explore these regions in ways previously impossible.
My research group is working to count forming stars in high-mass
protoclusters, with the ultimate aim of answering how the stellar
initial mass function (IMF) forms from gas. I will discuss recent and
ongoing efforts to count protostars and cores, measure their masses, and
measure the gas they came from. These include the ALMA-IMF large program
and comparable observations toward W49 and Sgr B2. I will highlight the
recently-discovered lines of salt (NaCl and KCl) and CS masers as tools
for measuring high-mass stars with disks. Finally, I will describe a
planned small satellite mission, PASHION, that will map the Paschen
Alpha line throughout the Galaxy.
