Monitoring the Galactic Centre with Australia Telescope Compact Array
A. Borkar, A. Eckart, C. Straubmeier +12
The supermassive black hole, Sagittarius A* (Sgr A*), at the centre of the Milky Way undergoes regular flaring activity which is thought to arise from the innermost region of the a…
Multiwavelength study of the flaring activity of Sgr A* in 2014 February-April
E. Mossoux, N. Grosso, H. Bushouse +8
The supermassive black hole Sgr A* is located at the Milky Way center. We studied its flaring activity close to the DSO/G2 pericenter passage to constrain the physical properties a…
Effect of an isotropic outflow from the Galactic centre on the bow-shock evolution along the orbit
Michal Zajacek, Andreas Eckart, Vladimir Karas +5
Motivated by the observations of several infrared-excess bow-shock sources and proplyd-like objects near the Galactic centre, we analyse the effect of a potential outflow from the…
The nuclear gas disk of NGC 1566 dissected by SINFONI and ALMA
S. Smajić, L. Moser, A. Eckart +5
We present the results of near-infrared H- and K-band European Southern Observatory SINFONI integral field spectroscopy of the Seyfert galaxy NGC 1566. We investigate the central k…
A low-luminosity type-1 QSO sample - A morphological study of nearby AGN hosts
Gerold Busch, Jens Zuther, Mónica Valencia-S. +2
There is growing evidence that every galaxy with a considerable spheroidal component hosts a supermassive black hole (SMBH) at its center. Strong correlations between the SMBH and…
Beating the confusion limit: The necessity of high angular resolution for probing the physics of Sagittarius A* and its environment: Opportunities for LINC-NIRVANA (LBT), GRAVITY (VLTI) and and METIS (E-ELT)
A. Eckart, N. Sabha, G. Witzel +16
The super-massive 4 million solar mass black hole (SMBH) SgrA* shows variable emission from the millimeter to the X-ray domain. A detailed analysis of the infrared light curves all…
Is IRAS 01072+4954 a True-Seyfert 2? Hints from Near Infrared Integral Field Spectroscopy
M. Valencia-S., J. Zuther, A. Eckart +4
In contrast to the predictions of the unified model, some X-ray unobscured Seyfert 2 galaxies have been discovered in the last decade. One of them, the starburst/Seyfert composite…
Optical Integral Field Spectroscopy of NGC 5850
M. Bremer, J. Scharwächter, A. Eckart +3
Here we present the preliminary results of the analysis of VIMOS observations of the central 4.5 kpc of the double-barred galaxy NGC 5850. We use optical diagnostic diagrams to stu…
