Thick disks of lenticular 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.

Structure of the Galaxies in the NGC 80 Group [PDF]
, 2009 BV-bands photometric data obtained at the 6-m telescope of the Special Astrophysical Observatory are used to analyze the structure of 13 large disk galaxies in the NGC 80 group.

Outer stellar disks of lenticular galaxies [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractBy studying the radial distribution of the properties of stellar populations in 15 nearby S0 galaxies, I have found that the outer stellar disks are mostly old, with SSP-equivalent ages of 8–15 Gyr, often being older than the bulges. This fact throws doubt on the currently accepted paradigm that S0 galaxies were formed at z=0.4 through the ...

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.

Globular Clusters in Lenticular Galaxies: NGC 3115 [PDF]
Symposium - International Astronomical Union, 1988 We present a progress report for the ongoing study of the globular cluster (GC) system around the edge-on lenticular galaxy NGC 3115. This object is one of the best targets for this kind of investigation, due to its proximity (~ 10 Mpc) and favourable inclination (for a deep photometric study and a review of the properties of NGC 3115, see Capaccioli ...

On the Classification of UGC1382 as a Giant Low Surface Brightness Galaxy [PDF]
, 2016 We provide evidence that UGC1382, long believed to be a passive elliptical galaxy, is actually a giant low surface brightness (GLSB) galaxy which rivals the archetypical GLSB Malin 1 in size.

S-PLUS: LEnticular Galaxies in Stripe 82
, 2021 This work is a Brazilian-Indian collaboration. It aims at investigating the structuralproperties of Lenticular galaxies in the Stripe 82 using a combination of S-PLUS (Southern Photometric Local Universe Survey) and SDSS data. S-PLUS is a noveloptical multi-wavelength survey which will cover nearly 8000 square degrees of the Southern hemisphere in the ...

The Structure of Stellar Disks in Isolated Lenticular Galaxies∗ [PDF]
The Astronomical Journal, 2020 Abstract We have obtained imaging data in two photometric bands, g and r, for a sample of 42 isolated lenticular galaxies with the Las Cumbres Observatory 1 m telescope network. We have analyzed the structure of their large-scale stellar disks.

Footprints in the sand: What can globular clusters tell us about NGC 4753 past? [PDF]
, 2015 NGC 4753 is a bright (M_V approx -22.3) lenticular galaxy. It is a very interesting target to test different theories of formation of lenticular galaxies, due to its low-density environment and complex structure.
