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…
Fabry-Perot observations at the 6m telescope
A. V. Moiseev, V. L. Afanasiev, S. N. Dodonov
A current status of the observations with Interferometer Fabry-Perot (IFP) at the 6m telescope are described. A reduction of the data obtaining with a new focal reducer SCORPIO in…
Helical structures in Seyfert galaxies
A. V. Moiseev, V. L. Afanasiev, S. N. Dodonov +2
The Seyfert galaxies with Z-shaped emission filaments in the Narrow Line Region (NLR) are considered. We assume that observable Z-shaped structures and velocity pattern of NLR may…
The extraordinarily bright optical afterglow of GRB 991208 and its host galaxy
A. J. Castro-Tirado, V. V. Sokolov, J. Gorosabel +50
Observations of the extraordinarily bright optical afterglow (OA) of GRB 991208 started 2.1 d after the event. The flux decay constant of the OA in the R-band is -2.30 +/- 0.07 up…
The structure and kinematics of AGN with ionization cones
A. V. Moiseev, V. L. Afanasiev, S. N. Dodonov +2
Results of 2D spectral observations for 4 Sy galaxies with ionization cones are presented. Images in the [OIII] line, velocity fields of the ionized gas, stellar velocity and veloc…
