Large-scale outflows in luminous QSOs revisited: The impact of beam smearing on AGN feedback efficiencies
B. Husemann, J. Scharwächter, V. N. Bennert +3
[Abridged] Enormous observational efforts have been made to constrain the energetics of AGN feedback by mapping the kinematics of the ionized gas on kpc scale. We study how the obs…
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…
The MUSE view of QSO PG1307+085: An elliptical galaxy on the relation interacting with its group environment
B. Husemann, V. N. Bennert, J. Scharwächter +2
We report deep optical integral-field spectroscopy with the MUSE of the luminous radio-quiet QSO PG1307+085 (z=0.154) obtained during the commissioning of the instrument. Given the…
The WiFeS S7 AGN survey: Current status and recent results on NGC 6300
J. Scharwächter, M. A. Dopita, P. Shastri +14
The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) is a targeted survey probing the narrow-line regions (NLRs) of a representative sample of ~140 nearby (z<0.02)…
The overmassive black hole in NGC 1277: new constraints from molecular gas kinematics
J. Scharwächter, F. Combes, P. Salomé +2
We report the detection of CO(1-0) emission from NGC 1277, a lenticular galaxy in the Perseus Cluster. NGC 1277 has previously been proposed to host an overmassive black hole (BH)…
Probing the Physics of Narrow Line Regions in Active Galaxies III: Accretion and Cocoon Shocks in the LINER NGC1052
Michael A. Dopita, I-Ting Ho, Linda L. Dressell +16
We present Wide Field Spectrograph (WiFeS) integral field spectroscopy and HST FOS spectroscopy for the LINER galaxy NGC 1052. We infer the presence of a turbulent accretion flow f…
Probing the Physics of Narrow Line Regions in Active Galaxies II: The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7)
Michael A. Dopita, Prajval Shastri, Rebecca Davies +14
Here we describe the \emph{Siding Spring Southern Seyfert Spectroscopic Snapshot Survey} (S7) and present results on 64 galaxies drawn from the first data release. The S7 uses the…
