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.

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.

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.

Lenticular Galaxy Formation - Possible Luminosity Dependence [PDF]
The Astrophysical Journal, 2007 We investigate the correlation between the bulge effective radius (r_e) and disk scale length (r_d), in the near-infrared K band for lenticular galaxies in the field and in clusters. We find markedly different relations between the two parameters as a function of luminosity.

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.

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.

A Chandra Observation of the Nearby Lenticular Galaxy NGC 5102: Where are the X-ray Binaries? [PDF]
, 2005 We present results from a 34 ks Chandra/ACIS-S observation of the nearby (d=3.1 Mpc) lenticular galaxy NGC 5102, previously shown to have an unusually low X-ray luminosity.

S-PLUS: LEnticular Galaxies in Stripe 82 (LEGS82) [PDF]
Anais da Academia Brasileira de Ciências, 2021 This work is a Brazilian-Indian collaboration. It aims at investigating the structural properties of Lenticular galaxies in the Stripe 82 using a combination of S-PLUS (Southern Photometric Local Universe Survey) and SDSS data.

Asymmetric Star Formation Triggered by Gas Inflow in a Barred Lenticular Galaxy PGC 34107 [PDF]
Astrophysical Journal, 2022 Comparing the inactive and gas-poor normal lenticular galaxies (S0s) in the local universe, we study a barred star-forming S0 galaxy, PGC 34107, which has been observed by the Centro Astronómico Hispano Alemán 3.5 m telescope and the Northern Extended ...

Thick disks of lenticular galaxies - 3D-photometric thin/thick disk decomposition of eight edge-on S0 galaxies [PDF]
Astronomy & Astrophysics, 2004 Thick disks are faint and extended stellar components found around several disk galaxies including our Milky Way. The Milky Way thick disk, the only one studied in detail, contains mostly old disk stars (~10 Gyr), so that thick disks are likely to trace the early stages of disk evolution.
