  • Bokkapitel (refereegranskat)abstract
    • <p>Fifteen sources known to be varying at low frequencies have been observed at six epochs during 1983–84 with a global VLBI array. Some of the sources show structural variations similar to the superluminals. Beaming effect may therefore play an important role at low as well as at higher frequencies.</p>

  • Bokkapitel (refereegranskat)abstract
    • <p>The purpose of this lecture is to introduce the VLBI user to the practical details of mapping radio sources. I will concentrate on data processing and mapping with the AIPS (Thompson and D’Addario, 1982)-package. Other data reduction systems do exist, e.g. the Caltech-package and OLAF. These differ from AIPS mostly in the <em>strategy</em> for reaching the final and “best” map. It is more important to know the method and to be careful than what reduction procedure is used.</p>

  • The quasars 1038+528 A and B
  • 1985
  • Ingår i: Astronomy and Astrophysics. - Les Ulis : EDP Sciences. - 0004-6361 .- 1432-0746. ; 142:1, s. 71-84
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>The results of VLBI observations of the quasars 1038 + 528 A and B at 2.8, 3.6, 13, and 18 cm at various times between November 1979 and March 1981 are reported. The observations and data calibration are described, as are the mapping and astrometric techniques applied in the study. Both quasars are found to have 'core-jet' morphologies. The core of the A quasar dominates its morphology at centrimetric wavelengths with the brightness temperature of its 400 pc long jet being about 1/100 that of the core. By contrast, the 'jet' in the B quasar is very short (about 70 pc); the tail of this jet has the steepest spectral index found to date in extragalactic compact sources, indicating that high electron losses are responsible for the shortness of the jet. No evidence for appreciable morphological change in the B quasar was found over the time span of the study, whereas a new feature may be emerging from the A quasar core at superluminal speed.</p>

  • Decimeter-wavelength structure in the quasar 3C 345
  • 1986
  • Ingår i: Pis'ma v Astronomicheskii Zhurnal. - Moscow : Izdatel'stvo Nauka. - 0320-0108. ; 12:1, s. 63-67
  • Tidskriftsartikel (refereegranskat)abstract
    • <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>

  • Studies of the 3c 345 Quasar Structure at Dm-Wavelengths
  • 1987
  • Ingår i: Observational evidence of activity in galaxies : proceedings of the 121st Symposium of the International Astronomical Union, held in Byurakan, Armenia, U.S.S.R., June 3-7, 1986. - Dordrecht : D. Reidel Publishing Group. - 90-277-2473-3 - 90-277-2474-1 ; s. 301-304
  • Konferensbidrag (refereegranskat)abstract
    • <p>The structure of the quasar 3C 345 has been studied at 18 and 49 cm wavelengths by VLBI method. The structure has a nucleus and a jet, which changes direction with distance from the nucleus. The continuum emission of the nucleus and the jet regions correspond to a source with a large optical depth, the cut frequence goes down with increasing distance from nucleus.</p>

  • High-resolution images of the Orion molecular ridge in the CS J = 2-1 transition
  • 1988
  • Ingår i: Astrophysical Journal. - Philadelphia, PA : Institute of Physics Publishing (IOPP). - 0004-637X .- 1538-4357. ; 325:1, s. 382-388
  • Tidskriftsartikel (refereegranskat)abstract
    • <p>The authors have constructed 7arcsec.5 resolution images of the CS J = 2-1 emission from a 3arcmin.5 section of the Orion molecular ridge using a maximum entropy algorithm to combine Owens Valley Millimeter-Wave Interferometer and Onsala Space Observatory 20 m data. The resulting images include all of the flux and have positional accuracy of 1arcsec-2arcsec on the small-scale features. The observed section of the ridge includes four condensations. The condensations have dimensions from 0.03 to 0.11 pc and virial massses from 30 to 80 M_sun;. Approximately 70% of the total mass within the 3arcmin region is contained in these condensations.</p>
