Abstract:

We have performed a submillimeter survey of the areas around 47 selected IRAS point sources of high luminosity. A number of new submm sources were found. The high multiplicity of the sources suggests that isolated massive-star formation is a rare event. In some cases the filaments near the young stellar objects (YSO) or between them were found. The pointers of massive star formation like masers, outflows and high-density knots were identified. Available catalogs in the near-infrared (2MASS), mid-infrared (MSX point sources) and radio continuum (NVSS at 1.4 GHz point sources) were correlated to our submm maps.
