Exponential bulges and antitruncated disks in lenticular galaxies
Olga K. Sil'chenko
The presence of exponential bulges and anti-truncated disks has been noticed in many lenticular galaxies. In fact, it could be expected because the very formation of S0 galaxies in…
Low-Luminosity Early-Type Galaxies in the NGC 128 Group
Igor Chilingarian, Olga Sil'chenko, Victor Afanasiev +1
We present spatially resolved kinematics and stellar population parameters for three low-luminosity galaxies in the NGC128 group obtained by means of 3D spectroscopy. We briefly di…
NBursts: Simultaneous Extraction of Internal Kinematics and Parametrized SFH from Integrated Light Spectra
Igor Chilingarian, Philippe Prugniel, Olga Sil'chenko +1
We present a novel approach for simultaneous extraction of stellar population parameters and internal kinematics from the spectra integrated along a line of sight. We fit a templat…
Age and metallicity of the bulges in lenticular galaxies
Olga K. Sil'chenko
Panoramic spectroscopic data of the sample of 80 nearby lenticular galaxies obtained with the Multi-Pupil Fiber Spectrograph of the 6-m telescope are presented. The SSP-equivalent…
Metallicity and age gradients in round elliptical galaxies
M. Baes, O. K. Sil'chenko, A. V. Moiseev +1
We probe the stellar population age and metallicity distributions in nearby elliptical galaxies over the largest extension to date. Long-slit spectroscopy is made by using the spec…
Kinematics and stellar populations of the dwarf elliptical galaxy IC 3653
Igor Chilingarian, Philippe Prugniel, Olga Sil'chenko +1
We present the first 3D observations of a diffuse elliptical galaxy (dE). The good quality data (S/N up to 40) reveal the kinematical signature of an embedded stellar disc, reminis…
