    • <p>The nuclear structure of the quasar 3C 345 has been surveyed at wavelength = 18 and 49 cm with two different VLBI networks. From the nucleus issues a jet, bending as it advances outward. Individual structure components are identified; their radio continuum and that of the nucleus indicate an optically thick source, the break in the spectrum shifting toward lower frequencies with increasing distance from the nucleus.</p>

  • Protostellar Condensations within the Orion Ridge
  • 1986
  • Ingår i: Astrophysical Journal. - Philadelphia, PA : Institute of Physics Publishing (IOPP). - 0004-637X .- 1538-4357. ; 304:2, s. L51-L55
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>Aperture synthesis observations of the CS J = 2 to 1 line and 95 GHz continuum emission from a 2 arcmin x 3 arcmin region around IRc2 in the OMC-1 molecular cloud have been obtained at 7.5 arcsec resolution with the Owens Valley Radio Observatory millimeter interferometer. These observations reveal four distinct condensations with the OMC-1 molecular ridge. The condensations lie along the edge of the bright central part of the H II region, M 42, suggesting that they may have been formed as a result of shock compression driven by the H II region. Their masses and densities, M about 50 solar masses and n about 10 to the 6th - 10 to the 7th/cu cm, suggest that the condensations will undergo further massive star formation on a short time scale (about 20,000 yr).</p>
