Properties of Stellar Populations in Isolated Lenticular Galaxies [PDF]

, 2014
In this paper we present the results of long-slit spectral observations for a sample of isolated lenticular galaxies, made with the SCORPIO and SCORPIO-2 spectrographs of the 6-meter BTA telescope of the SAO RAS.

Bar fraction in lenticular galaxies: dependence on luminosity and environment [PDF]

, 2010
We present a study of bars in lenticular galaxies based on a sample of 371 galaxies from the SDSS-DR 7 and 2MASS in optical and near-infrared bands, respectively.

Angular Momentum across the Hubble sequence from the CALIFA survey [PDF]

, 2014
We investigate the stellar angular momentum of galaxies across the Hubble sequence from the CALIFA survey. The distribution of CALIFA elliptical and lenticular galaxies in the $\lambda_{\rm Re}-\epsilon_{\rm e}$ diagram is consistent with that shown by ...

Properties of the Photometric Components of Lenticular Galaxies

Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012
After almost one century since their definition, the origin of lenticular galaxies is still a matter of debate. Several formation processes have been proposed in order to explain the wide variety of their observational properties. These properties could indicate that the class of lenticulars is a family formed by galaxies with different formations and ...

Isolated lenticular galaxies: properties and evolution [PDF]

arXiv, 2014
This work is dedicated to investigation of galaxies that do not fit into a common scenario of galaxy formation - isolated lenticular galaxies. We have studied stellar populations and ionized gas content of a sample of 22 lenticular galaxies (among those 4 targets have appeared to be of erroneous morphological classification) by undertaking deep long ...

Stellar nuclei and inner polar disks in lenticular galaxies [PDF]

Astronomical Journal v. 152, no. 3, September 2016, Article Id. 73, 2016
I analyze statistics of the stellar population properties for stellar nuclei and bulges of nearby lenticular galaxies in different environments by using panoramic spectral data of the integral-field spectrograph SAURON retrieved from the open archive of Isaac Newton Group.

Near-infrared bulge-disc correlations of lenticular galaxies [PDF]

Mon.Not.Roy.Astron.Soc.394:1991B,2009, 2008
We consider the luminosity and environmental dependence of structural parameters of lenticular galaxies in the near-infrared K band. Using a two-dimensional galaxy image decomposition technique, we extract bulge and disk structural parameters for a sample of 36 lenticular galaxies observed by us in the K band.

Luminosities of Barred and Unbarred S0 Galaxies [PDF]

, 2012
Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for objects classified in blue light, and for those that were classified in ...

A catalog of warps in spiral and lenticular galaxies in the Southern hemisphere [PDF]

Astron.Astrophys.399:457-468,2003, 2002
A catalog of optical warps of galaxies is presented. This can be considered complementary to that reported by Sanchez-Saavedra et al., with 42 galaxies in the northern hemisphere, and to that by Reshetnikov & Combes, with 60 optical warps. The limits of the present catalog are: logr25 > 0.60, B_{t} < 14.5, delta(2000) < 0, -2.5 < t < 7.

Lenticular Galaxies and Their Environments [PDF]

, 2009
It is widely believed that lenticular (S0) galaxies were initially spirals from which the gas has been removed by interactions with hot cluster gas, or by ram-pressure stripping of cool gas from spirals that are orbiting within rich clusters of galaxies.
