A low-luminosity type-1 QSO sample. V. Overluminous host spheroids and their excitation mechanisms
Gerold Busch, Nastaran Fazeli, Andreas Eckart +6
We present near-infrared (NIR) -band longslit spectra of eleven galaxies which are obtained with SOFI at the NTT (ESO). The galaxies are chosen from the low-luminosity type-1…
Line and Continuum Variability in Active Galaxies
Y. E. Rashed, A. Eckart, M. Valencia-S. +5
We compared optical spectroscopic and photometric data for 18 AGN galaxies over 2 to 3 epochs, with time intervals of typically 5 to 10 years. We used the Multi-Object Double Spect…
The Galactic Center Black Hole Laboratory
A. Eckart, S. Britzen, M. Valencia-S. +8
The super-massive 4 million solar mass black hole Sagittarius~A* (SgrA*) shows flare emission from the millimeter to the X-ray domain. A detailed analysis of the infrared light cur…
