Size and Properties of the NLR in the Seyfert-2 Galaxy NGC 1386
Nicola Bennert, Bruno Jungwiert, Stefanie Komossa +2
We study the narrow-line region (NLR) of the Seyfert-2 galaxy NGC 1386 by means of long-slit spectroscopy obtained with FORS1 at the VLT. We use the galaxy itself for subtracting t…
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…
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…
The ISO-2MASS AGN survey: On the type-1 sources
C. Leipski, M. Haas, H. Meusinger +9
We combined the ISOCAM Parallel Mode Survey at 6.7 micron (LW2 filter) with the Two Micron All Sky Survey in order to obtain a powerful tool to search for AGN independent of dust e…
Obscured Activity: AGN, Quasars, Starbursts and ULIGs observed by the Infrared Space Observatory
Aprajita Verma, Vassilis Charmandaris, Ulrich Klaas +2
Some of the most active galaxies in the Universe are obscured by large quantities of dust and emit a substantial fraction of their bolometric luminosity in the infrared. Observatio…
VPMS J1342+2840 - an unusual quasar from the variability and proper motion survey
H. Meusinger, D. Froebrich, M. Haas +3
We report the discovery of the highly peculiar, radio-loud quasar VPMS J1342+2840 (z ~ 1.3) from the variability and proper motion survey. We present spectroscopic, imaging and pho…
