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…
What produces the extended LINER-type emission in the NUGA galaxy NGC 5850?
Marcus Bremer, Julia Scharwächter, Andreas Eckart +5
(Abridged) The role of low ionization nuclear emission region (LINER) galaxies within the picture of active galactic nuclei (AGN) has been controversial. It is still not clear whet…
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…
The Central 3 kpc of NGC 5850
M. Bremer, J. Scharwächter, A. Eckart +5
NGC 5850 is a nearby (z=0.0085) early type spiral galaxy classified as LINER. It is considered as a prototype double-barred system. Our optical Integral Field Spectroscopic (IFS) d…
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…
A statistical study of SDSS radio-emitters
Mariangela Vitale, Jens Zuther, Macarena García-Marín +4
The cross-correlation of the Sloan Digital Sky Survey Data Release 7 with the Faint Images of the Radio Sky at Twenty-Centimeters survey allows for a multiwavelength statistical st…
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…
Instanton Cosmology and Domain Walls from M-theory and String Theory
M. Bremer, M. J. Duff, H. Lu +2
The recent proposal by Hawking and Turok for obtaining an open inflationary universe from singular instantons makes use of low-energy effective Lagrangians describing gravity coupl…
Dirac Quantisation Conditions and Kaluza-Klein Reduction
M. S. Bremer, H. Lu, C. N. Pope +1
We present the form of the Dirac quantisation condition for the p-form charges carried by p-brane solutions of supergravity theories. This condition agrees precisely with the condi…
