Young Stellar Objects close to Sgr A*
B. Jalali, I. Pelupessy, A. Eckart +6
We aim at modelling small groups of young stars such as IRS 13N, 0.1 pc away from Sgr A*, which is suggested to contain a few embedded massive young stellar objects. We perform hyd…
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…
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…
Discovery of an Intermediate Mass Black Hole at the center of the starburst/Seyfert composite galaxy IRAS 01072+4954
M. Valencia-S., A. Eckart, J. Zuther +8
The starburst/Seyfert composite galaxy IRAS 01072+4954 (z=0.0236) is an enigmatic source that combines a Seyfert~1-like X-ray emission with a starburst optical spectrum that lacks…
