Herschel and Galaxies/AGN
Peter Barthel
Herschel will represent a breakthrough in the study of nearby gas-rich and gas-poor galaxies, as it will for the first time permit imaging photometric and spectroscopic observation…
On the viewing angle to broad-lined radio galaxies
J. Dennett-Thorpe, P. D. Barthel, I. M. van Bemmel
We address the nature of broad-lined radio galaxies, in particular their radio axis orientation, using new, matched resolution, dual frequency radio observations of a sample of twe…
ISOPHOT observations of 3CR quasars and radio galaxies
Ilse M. van Bemmel, Peter D. Barthel, Thijs de Graauw
In order to check for consistency with the radio-loud AGN unification scheme, ISOPHOT data obtained for two small sets of intermediate redshift steep-spectrum 3CR radio galaxies an…
Radio imaging of core-dominated high redshift quasars
Peter D. Barthel, Marianne Vestergaard, Colin J. Lonsdale
VLA imaging at kiloparsec-scale resolution of sixteen core-dominated radio-loud QSOs is presented. Many objects appear to display variable radio emission and their radio morphologi…
Infrared emission from radio-loud active nuclei
Ilse M. van Bemmel, Peter D. Barthel, Thijs de Graauw
In order to test the unification scheme for double-lobed radio sources, the far-infrared properties of matched samples of radio-galaxies and radio-loud quasars were studied using I…
Nature of 60 micron emission in 3C47, 3C207 and 3C334
Ilse M. van Bemmel, Peter D. Barthel, Min S. Yun
We try to explain the unusually high far-infrared emission seen by IRAS in the double-lobed radio-loud quasars 3C47, 3C207 and 3C334. High resolution cm--mm observations were carri…
