Arp 58 and Arp 68: two M 51- type systems
Anatoly V. Zasov, Anna S. Saburova, Oleg V. Egorov +2
We study two M 51-type systems Arp 68 and Arp 58, which strongly differ by their stellar masses, gas content and environment. Long-slit spectral observations obtained at the 6-m te…
Multi-segment and Echelle stellar spectra processing issues and how to solve them
Sviatoslav Borisov, Igor Chilingarian, Evgenii Rubtsov +7
High-quality stellar spectra are in great demand now - they are the most important ingredient in the stellar population synthesis to study galaxies and star clusters. Here we descr…
The insight into the dark side. I. The pitfalls of the dark halo parameters estimation
Anna Saburova, Anastasia Kasparova, Ivan Katkov
We examined the reliability of estimates of pseudoisothermal, Burkert and NFW dark halo parameters for the methods based on the mass-modelling of the rotation curves.To do it we co…
Tidal bridge and tidal dwarf candidates in the interacting system Arp194
Anatoly Zasov, Anna Saburova, Oleg Egorov +1
Arp194 is a system of recently collided galaxies, where the southern galaxy (S) passed through the gaseous disc of the northern galaxy (N) which in turn consists of two close compo…
On the surface density of dark matter haloes
A. Saburova, A. Del Popolo
In this article, we test the conclusion of Donato et al. (2009) concerning the universality of the DM halo surface density . According to our study, the dispersion o…
To be or not to be oblate: the shape of the dark matter halo in the polar ring galaxies
S. A. Khoperskov, A. V. Moiseev, A. V. Khoperskov +1
With the aim to determine the spatial distribution of the dark matter halo, we investigate two polar ring galaxies NGC 4262 and SPRC-7. For both galaxies the stellar kinematics dat…
