A New Radio Loudness Diagnostic for Active Galaxies: A Radio-to-Mid-Infrared Parameter
, 2010 We have studied the relationship between the nuclear (high-resolution) radio emission, at 8.4GHz (3.6cm) and 1.4GHz (20cm), the [O IV) (gamma)25.89 micron, [Ne III] (gamma)l5.56 micron and [Ne II] (gamma)l2.81 micron emission lines and the black hole ...

Comparing six evolutionary population synthesis models by performing spectral synthesis for galaxies
, 2010 Aims. We compare six popularly used evolutionary population synthesis (EPS) models by fitting the full optical spectra of six representative types of galaxies (star-forming and composite galaxies, Seyfert 2s, LINERs, E+A, and early-type galaxies) taken

Galaxienaktivitaet als Resultat von Gezeitenwechselwirkung Abschlussbericht
, 1996 There is growing evidence that nonthermal activity in the nuclei of galaxies (Seyfert activity) and starbursts are triggered due to galaxy interaction. In most Seyfert galaxies a composition of both components has been observed.

ISO observations of hot dust in the nucleus of the S0 galaxy NGC3998
, 2007 . ISOCAM maps of the Seyfert 1 S0 galaxy NGC 3998 between 4:5¯m and 15¯m detect both extended emission from the bulge stars and strong point source emission from the nucleus.
