MAMBO 1.25mm observations of 3CR radio galaxies and quasars at z=1.5: On the debate of the unified schemes
Martin Haas, Rolf Chini, Sven Mueller +2
In order to explore the nature of the 850 micron flux difference between powerful radio galaxies and steep radio-spectrum quasars at z=1.5 reported by Willott et al. (2002), we hav…
Dust in 3CR radio galaxies: On the FR1-FR2 difference
S. A. H. Mueller, M. Haas, R. Siebenmorgen +4
We compare three 3CR samples of 11 FR1 galaxies, 17 FR2 galaxies and 18 lobe-dominated quasars contained in the ISO Data Archive. In contrast to the powerful FR2 galaxies with edge…
The ISOPHOT-MAMBO survey of 3CR radio sources: Further evidence for the unified schemes
M. Haas, S. A. H. Mueller, F. Bertoldi +9
We present the complete set of ISOPHOT observations of 3CR radio galaxies and quasars, which are contained in the ISO Data Archive, providing 75 mid- and far-infrared spectral ener…
Mid-infrared selection of AGN
Martin Haas, Ralf Siebenmorgen, Christian Leipski +6
Since a large fraction of active galactic nuclei (AGN) is missed in common UV-excess surveys and is even hard to find in radio, near-IR and X-ray surveys, we have used a new AGN se…
