The Diversity of Thick Galactic Discs
Anastasia V. Kasparova, Ivan Yu. Katkov, Igor V. Chilingarian +3
Although thick stellar discs are detected in nearly all edge-on disc galaxies, their formation scenarios still remain a matter of debate. Due to observational difficulties, there i…
A complex stellar line-of-sight velocity distribution in the lenticular galaxy NGC 524
I. Katkov, I. Chilingarian, O. Sil'chenko +2
We present the detailed study of the stellar and gaseous kinematics of the luminous early-type galaxy NGC 524 derived from the long-slit spectroscopic observations obtained with th…
Stellar populations and galaxy evolution in the NGC 80 group
Olga K. Silchenko, Victor L. Afanasiev
We have studied the central parts of seven early-type galaxies -- the members of the X-ray-bright galaxy group NGC 80 -- by means of integral-field spectroscopy at the Russian 6m t…
Ionized and neutral gas in the peculiar star/cluster complex in NGC 6946
Yu. N. Efremov, V. L. Afanasiev, E. J. Alfaro +8
The characteristics of ionized and HI gas in the peculiar star/cluster complex in NGC 6946, obtained with the 6-m telescope (BTA) SAO RAS, the Gemini North telescope, and the Weste…
Diffuse elliptical galaxies, the first 3D spectroscopic observations
Igor Chilingarian, Philippe Prugniel, Olga Silchenko +1
Diffuse elliptical galaxies (or dwarfs) are the numerically dominant population in clusters like Virgo and Fornax. They carry only a few percent of the baryonic mass but are very s…
Stellar Population Properties in the Nuclei and Bulges of the Nearby Lenticular Galaxies
Olga K. Silchenko
The properties of stellar populations in the centers of 54 nearby lenticular galaxies are investigated by means of 2D spectroscopy, with the Multi-Pupil Spectrograph of the 6m tele…
