Lenticular galaxy IC 719: current building of the counterrotating large-scale stellar disk
Ivan Yu. Katkov, Olga K. Sil'chenko, Victor L. Afanasiev
We have obtained and analyzed long-slit spectral data for the lenticular galaxy IC 719. In this gas-rich S0 galaxy, its large-scale gaseous disk counterrotates the global stellar d…
Is dynamic heating of stellar disk inevitable?
A. Zasov, A. Saburova, I. Katkov
Major mergers or/and the repeated minor mergers lead to dynamical heating of disks of galaxies. We analyze the available data on the velocity dispersion of stellar disks of S-S0 ga…
Supermassive Black Holes and Kinematics of Disc Galaxies
A. V. Zasov, A. M. Cherepashchuk, I. Yu. Katkov
The statistical relations between the masses of supermassive black holes (SMBHs) in disk galaxies and the kinematic properties of their host galaxies are analyzed. We use the radia…
Hoag's Object: Evidence for Cold Accretion onto an Elliptical Galaxy
Ido Finkelman, Alexei Moiseev, Noah Brosch +1
(Abridged) We present new photometric and spectroscopic observations of the famous Hoag's Object, a peculiar ring galaxy with a central roundish core. The nature of Hoag's Object i…
Stars and ionized gas in S0 galaxy NGC 7743: an inclined large-scale gaseous disk
Ivan Yu. Katkov, Alexei V. Moiseev, Olga K. Sil'chenko
We used deep long-slit spectra and integral-field spectral data to study the stars and ionized gas kinematics and stellar population properties in the lenticular barred galaxy NGC…
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…
