Unification of 3CR Radio Galaxies and Quasars
Bernhard Schulz, Ralf Siebenmorgen, Martin Haas +2
We have observed seven powerful FR2 radiogalaxies and seven quasars with the Spitzer IRS. Both samples are comparable in both, redshift range and isotropic 178 Hz luminosity. Both…
Dust in starburst nuclei and ULIRGs: SED models for observers
Ralf Siebenmorgen, Endrik Kruegel
We provide a library of some 7000 SEDs (available at www.eso.org/~rsiebenm) for the nuclei of starburst and ultra luminous galaxies. Its purpose is to quickly obtain estimates of t…
Radio continuum monitoring of the extreme carbon star IRC+10216
K. M. Menten, M. J. Reid, E. Kruegel +2
We describe Very Large Array observations of the extreme carbon star IRC+10216 at 8.4, 14.9, and 22.5 GHz made over a two year period. We find possible variability correlated with…
Spitzer IRS spectroscopy of 3CR radio galaxies and quasars: Testing the unified schemes
Martin Haas, Ralf Siebenmorgen, Bernhard Schulz +2
With the Spitzer Space Telescope Infrared Spectrograph (IRS) we have observed seven powerful FR2 radio galaxies and seven quasars. Both samples, the galaxies and the quasars, are c…
The protostellar system HH108MMS
R. Siebenmorgen, E. Kruegel
We probe the region around the protostar HH108MMS by deep mid infrared photometric and polarimetric imaging. The protostar is detected at 14mu in absorption against the diffuse bac…
CO band emission from MWC349: I. First overtone bands from a disk or from a wind?
M. Kraus, E. Kruegel, C. Thum +1
We observed the near infrared emission in the wavelength range 2.28-2.50 micron from the peculiar B[e]-star MWC349. The spectra contain besides the strong IR continuum the first ov…
