A low-luminosity type-1 QSO sample; III. Optical spectroscopic properties and activity classification
E. Tremou, M. Garcia-Marin, J. Zuther +4
We report on the optical spectroscopic analysis of a sample of 99 low-luminosity quasi-stellar objects (LLQSOs) at base the Hamburg/ESO QSO survey (HES). The LLQSOs pr…
Galaxy evolution across the optical emission-line diagnostic diagrams?
M. Vitale, L. Fuhrmann, M. Garcia-Marin +3
The discovery of the M-sigma relation, the local galaxy bimodality, and the link between black-hole and host-galaxy properties, have raised the question whether AGN play a role in…
Nuclei of Seyfert galaxies and QSOs - Central engine and conditions of star formation. Workshop summary and open questions
M. Valencia-S., J. Zuther, M. Vitale +5
Observationally established correlations between black hole mass and host galaxy structural/dynamical properties (like the M_BH - sigma relation) give support to the idea of an int…
The infrared K-band identification of the DSO/G2 source from VLT and Keck data
Andreas Eckart, M. Horrobin, S. Britzen +24
A fast moving infrared excess source (G2) which is widely interpreted as a core-less gas and dust cloud approaches Sagittarius A* (SgrA*) on a presumably elliptical orbit. VLT K_s-…
The Galactic Center as a Paradigm for Low Luminosity Nuclei? The K-band identification of the DSO/G2 source from VLT and Keck data
Andreas Eckart, S. Britzen, M. Horrobin +27
The super-massive 4 million solar mass black hole (SMBH) SgrA* shows flare emission from the millimeter to the X-ray domain. The nucleus of the Milky Way has properties (stellar cl…
