Shape parameters of Galactic open clusters
N. V. Kharchenko, P. Berczik, M. I. Petrov +4
(abridged) In this paper we derive observed and modelled shape parameters (apparent ellipticity and orientation of the ellipse) of 650 Galactic open clusters identified in the ASCC…
High resolution in z-direction: The simulation of disc-bulge-halo galaxies using the particle-mesh code SUPERBOX
R. Bien, A. Just, P. Berczik +1
SUPERBOX is known as a very efficient particle-mesh code with highly-resolving sub-grids. Nevertheless, the height of a typical galactic disc is small compared to the size of the w…
Post-Newtonian simulations of super-massive black hole binaries in galactic nuclei
I. Berentzen, M. Preto, P. Berczik +2
We present some preliminary results from recent numerical simulations that model the evolution of super-massive black hole (SMBH) binaries in galactic nuclei. Including the post-Ne…
High-order 3D Voronoi tessellation for identifying Isolated galaxies, Pairs and Triplets
A. Elyiv, O. Melnyk, I. Vavilova
Geometric method based on the high-order 3D Voronoi tessellation is proposed for identifying the single galaxies, pairs and triplets. This approach allows to select small galaxy gr…
Extremely metal-poor star-forming galaxies. New detections and general morphological and photometric properties
P. Papaderos, N. G. Guseva, Y. I. Izotov +1
(abridged) We present long-slit spectroscopy with the 3.6m ESO telescope of eight HII regions in seven star-forming (SF) dwarf galaxies, discovered in SDSS DR4 and 6dFGRS. In addit…
MHS sunspot model from deep sub-photospheric to chromospheric layers
E. Khomenko, M. Collados
In order to understand the influence of magnetic fields on the propagation properties of waves, as derived from different local helioseismology techniques, forward modeling of wave…
