Inner Polar Rings in Regular Lenticular Galaxies [PDF]
The Astronomical Journal, 2004 We have investigated a sample of S0 galaxies, mostly with circumnuclear dust lanes orthogonal to their major axes, chosen from Hubble Space Telescope Wide Field Planetary Camera 2 images. Two-dimensional spectroscopy undertaken with the Multipupil Fiber Spectrograph of the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of

Exponential bulges and antitruncated disks in lenticular galaxies [PDF]
Proceedings of the International Astronomical Union, 2008 The presence of exponential bulges and anti-truncated disks has been noticed in many lenticular galaxies. In fact, it could be expected because the very formation of S0 galaxies includes various processes of secular evolution. We discuss how to distinguish between a pseudobulge and an anti-truncated disk, and also what particular mechanisms may be ...

Spectroscopic bulge-disc decomposition: a new method to study the evolution of lenticular galaxies [PDF]
, 2012 A new method for spectroscopic bulge–disc decomposition is presented, in which the spatial light profile in a two-dimensional spectrum is decomposed wavelength by wavelength into bulge and disc components, allowing separate one-dimensional spectra for ...

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.

Distribution and Motions of Atomic Hydrogen in Lenticular Galaxies [PDF]
Symposium - International Astronomical Union, 1983 We report the results of HI observations of eleven gas-rich SO/SOa galaxies with the Westerbork Synthesis Telescope. The majority of these galaxies have most of their hydrogen outside the optical body, in annular configurations with diameters ~2 times the optical. These outer gas rings are often clumped, incomplete, and in approximately circular motion.

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.

Chromodynamical analysis of lenticular galaxies using globular clusters and planetary nebulae [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Recovering the origins of lenticular galaxies can shed light on the understanding of galaxy formation and evolution, since they present properties that can be found in both elliptical and spiral galaxies.

3D spectroscopy of candidate double-barred lenticular galaxies [PDF]
arXiv, 2008 Significant fraction of barred galaxies hosts secondary bar-like structures on optical and NIR images. The circumnuclear dynamics of double-barred objects are still not well understood, observational data concerning kinematics are incomplete and inconsistent.

Statistical study of warps in a sample of spiral and lenticular galaxies
NRIAG Journal of Astronomy and Geophysics, 2016 AbstractA sample of edge-on (or nearly edge-on) spiral and lenticular galaxies is selected to study the warp phenomenon in their disks. This sample contains 36 disk galaxies selected from Watanabe’s catalogue (Watanabe, 1983). We investigate the existence of physical relations between photometric and spectroscopic parameters and the warp degree of ...

Splitting the lentils: Clues to galaxy/black hole coevolution from the discovery of offset relations for non-dusty versus dusty (wet-merger-built) lenticular galaxies in the Mbh-M*, spheroid and Mbh-M*, galaxy diagrams [PDF]
Monthly notices of the Royal Astronomical Society, 2023 This work advances the (galaxy morphology)-dependent (black hole mass, Mbh)-(spheroid/galaxy stellar mass, M*) scaling relations by introducing ‘dust bins’ for lenticular (S0) galaxies.
