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

Monthly Notices of the Royal Astronomical Society: Letters, 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.

Lenticular Galaxies and Their Environments [PDF]

The Astrophysical Journal, 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.

NGC 1436: the making of a lenticular galaxy in the Fornax cluster [PDF]

Monthly Notices of the Royal Astronomical Society, 2023
ABSTRACT We study the evolutionary path of the Fornax Cluster galaxy NGC 1436, which is known to be currently transitioning from a spiral into a lenticular morphology. This galaxy hosts an inner star-forming disc and an outer quiescent disc, and we analyse data from the MeerKAT Fornax Survey, ALMA, and the Fornax 3D survey to study the ...

Properties of Stellar Populations in Isolated Lenticular Galaxies [PDF]

Astrophysical Bulletin, 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. By applying full spectral fitting technique using the stellar population evolutionary synthesis models, we have measured the radial profiles ...

Formation of a Massive Lenticular Galaxy Under the Tidal Interaction with a Group of Dwarf Galaxies [PDF]

The Astrophysical Journal Letters, 2023
Based on the atomic-hydrogen (H i ) observations using the Five-hundred-meter Aperture Spherical radio Telescope, we present a detailed study of the gas-rich massive S0 galaxy NGC 1023 in a nearby galaxy group.

Lenticular galaxies with UV-rings [PDF]

Astronomy Letters, 2011
By using the public UV imaging data obtained by the GALEX (Galaxy Ultraviolet Explorer) for nearby galaxies, we have compiled a list of lenticular galaxies possessing ultraviolet rings - starforming regions tightly confined to particular radial distances

Creating lenticular galaxies with major mergers [PDF]

Proceedings of the International Astronomical Union, 2016
Lenticular galaxies (S0s) represent the majority of early-type galaxies in the local Universe, but their formation channels are still poorly understood. While galaxy mergers are obvious pathways to suppress star formation and increase bulge sizes, the marked parallelism between spiral and lenticular galaxies (e.g.

PGC 44685: A Dwarf Star-forming Lenticular Galaxy with a Wolf–Rayet Population

The Astrophysical Journal
Lenticular galaxies (S0s) are formed mainly from the gas stripping of spirals in the cluster. But how S0s form and evolve in the field is still in need of being resolved.

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 ...

Age and metallicity of the bulges in lenticular galaxies [PDF]

Proceedings of the International Astronomical Union, 2007
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 ages, [Z/H], and [Mg/Fe] are determined through the Lick indices H-beta, Mgb, and separately for the nuclei and for the bulges.
