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 the Photometric Components of Lenticular Galaxies [PDF]
Advances in Astronomy, 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.

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.

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.

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 ...

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

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

Stellar counter-rotation in lenticular galaxy NGC 448 [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 The counter-rotation phenomenon in disc galaxies directly indicates a complex galaxy assembly history which is crucial for our understanding of galaxy physics. Here we present the complex data analysis for a lenticular galaxy NGC 448, which has been recently suspected to host a counter-rotating stellar component.

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.
