A low-luminosity type-1 QSO sample: I. Overluminous host spheroidals or undermassive black holes?
Gerold Busch, Jens Zuther, Mónica Valencia-S. +6
Recognizing the properties of the host galaxies of quasi-stellar objects (QSOs) is essential to understand the suspected coevolution of central supermassive black holes (BHs) and t…
A low-redshift low luminosity QSO sample: Comparison with NUGA galaxies and PG QSOs and first interferometric images of three sample members
Lydia Moser, Jens Zuther, Sebastian Fischer +5
The low luminosity QSO (LLQSO) sample consists of type 1 active galactic nuclei (AGN) up to a redshift of z=0.06 in the Hamburg/ESO QSO survey. Its purpose is to study how the brig…
High-resolution observations of SDSS J080800.99+483807.7 in the optical and radio domains. A possible example of jet-triggered star formation
Y. E. Rashed, J. Zuther, A. Eckart +5
Double-lobe radio galaxies are ideally suited to investigate the interaction of the individual components of the radio structure with the intergalactic medium and the interstellar…
Are Narrow Line Seyfert 1s a special class of Active Galactic Nuclei?
M. Valencia-S., J. Zuther, A. Eckart +12
No. Due to their apparently extreme optical to X-ray properties, Narrow Line Seyfert 1s (NLSy1s) have been considered a special class of active galactic nuclei (AGN). Here, we summ…
