Abstract:
We present a complete sample of molecular clumps containing compact
and ultracompact HII (UC HII) regions between l=10° and 60°
and |b|<1°, identified by combining the APEX Telescope Large Area
Survey of the Galaxy submm and CORNISH radio continuum surveys with
visual examination of archival infrared data. Our sample is complete
to optically thin, compact and UC HII regions driven by a zero-age
main-sequence star of spectral type B0 or earlier embedded within a
1000M☉ clump. In total we identify 213 compact and UC HII
regions, associated with 170 clumps. Unambiguous kinematic distances
are derived for these clumps and used to estimate their masses and
physical sizes, as well as the Lyman continuum fluxes and sizes of
their embedded HII regions.
Description:
Derived clump parameters for ATLASGAL clumps associated with compact
HII regions identified by the CORNISH 5GHz radio continuum survey.
