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…
A new method for reconstructing the density distribution of matter in the disks of spiral galaxies from the rotation velocity curve in it
Alexander Shatskiy, Igor Novikov, Olga K. Sil'chenko +2
In this paper we propose a new method for reconstructing the surface density of matter in flat disks of spiral galaxies. The surface density is expressed through observational rota…
