SED models of AGN
Ralf Siebenmorgen, Andreas Efstathiou
Present AGN models aiming to account for the observed infrared SEDs consider a physical description of the dust and a solution of the radiative transfer problem. Mid infrared spect…
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…
Thermal infrared observations of near-Earth asteroid 2002 NY40
T. G. Mueller, M. F. Sterzig, O. Schuetz +2
We obtained N-band observations of the Apollo asteroid 2002 NY40 during its close Earth fly-by in August 2002 with TIMMI2 at the ESO 3.6 m telescope. The photometric measurement al…
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…
