Molecular gas in NUclei of GAlaxies (NUGA): VIII The Seyfert 2 NGC6574
E. Lindt-Krieg, A. Eckart, R. Neri +4
Within the frame of the NUclei of GAlaxies (NUGA) project, we have determined the distribution and kinematics of the molecular gas within the central kpc with high spatial resoluti…
The enigma of GCIRS 3 - Constraining the properties of the mid-infrared reference star of the central parsec of the Milky Way with optical long baseline interferometry
J. -U. Pott, A. Eckart, A. Glindemann +3
GCIRS3 is the most prominent MIR source in the central pc of the Galaxy. NIR spectroscopy failed to solve the enigma of its nature. The properties of extreme individual objects of…
NUclei of GAlaxies: V. Radio emission in 7 NUGA sources
M. Krips, A. Eckart, T. P. Krichbaum +10
We present high angular resolution radio snap-shot observations of seven nearby low-luminosity active galaxies (LLAGN) from the NUclei of GAlaxies (NUGA) survey. The observations w…
VLT-SINFONI observations of Mrk 609 - A showcase for X-ray active galaxies chosen from a sample of AGN suitable for adaptive optics observations with natural guide stars
J. Zuther, J. -U. Pott, C. Iserlohe +2
We will present first results of ESO-VLT AO-assisted integral-field spectroscopy of a sample of X-ray bright AGN with redshifts of 0.04 < z < 1. We constructed this sample by cross…
VLTI/MIDI measurements of extended mid-infrared emission in the Galactic Center
J. -U. Pott, A. Eckart, A. Glindemann +2
We investigated with MIDI the extension of dusty mid-infrared excess sources (IRS 1W, IRS 10W, IRS 2, IRS 8) in immediate vicinity to the black hole (BH) at the GC. We derive 3…
A feasibility study of future observations with MIDI and other VLTI science instruments: The example of the Galactic Center
J. -U. Pott, A. Glindemann, A. Eckart +4
VLT-Interferometry will allow imaging of the Galactic Center (GC) and the nuclei of extragalactic sources at an angular resolution of a few milliarcseconds. VLTI will be a prime in…
VLTI observations of IRS~3: The brightest compact MIR source at the Galactic Centre
J. -U. Pott, A. Eckart, A. Glindemann +7
The dust enshrouded star IRS~3 in the central light year of our galaxy was partially resolved in a recent VLTI experiment. The presented observation is the first step in investigat…
Relativistic jet motion in the core of the radio-loud quasar J1101+7225
J. -U. Pott, A. Eckart, M. Krips +4
Multi-epoch GHz Very Long Baseline Interferometry (VLBI) data of the radio-loud quasar J1101+7225 were analyzed to estimate the proper motion of extended optically thin jet compone…
The Warped Gas and Dust Lane in NGC 3718
M. Krips, J. -U. Pott, A. Eckart +2
We present the first observations of molecular line emission in NGC 3718 with the IRAM 30m and the Plateau de Bure Interferometer. This galaxy is an impressive example for a strong…
