Abstract:
Most work on high-mass star formation has focused on observations of
young massive stars in protoclusters. Very little is known about the
preceding stage. Here, we present a new high-resolution study of
pre-protocluster regions in tracers exclusively probing the coldest
and dense gas (NH2 D). The two target regions G29.96-0.02 and
G35.20-1.74 (W48) are drawn from the SCAMPS project, which searches
for pre-protoclusters near known ultracompact HII regions. We used our
data to constrain the chemical, thermal, kinematic, and physical
conditions (i.e., densities) in G29.96e and G35.20w. NH3, NH2 D,
HCO+, and continuum emission were mapped using the VLA, PdBI, and
BIMA.
