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. These properties could indicate that the class of lenticulars is a family formed by galaxies with different formations and ...

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.

Spectroscopic Study of Globular and Fuzzy Clusters in Lenticular Galaxy NGC 1023 [PDF]

The Astrophysical Journal
We here report the results from spectroscopic observations of a sample of 26 globular cluster (GC) and 21 faint fuzzy (FF) candidates in the lenticular galaxy NGC 1023 using the 10.4 m Gran Telescopio Canarias.

Inner structure of the lenticular galaxy NGC 3384 [PDF]

Monthly Notices of the Royal Astronomical Society, 1984
La region interne de la galaxie lenticulaire NGC 3384 presente une structure complexe. La haute resolution (FWHM≃0,7 arc sec) obtenue pour cette etude photometrique permet de montrer que la faible structure allongee croisant le bulbe perpendiculairement a l'axe principal de la galaxie n'est probablement pas une barre, mais un petit anneau polaire de ...

NGC 1436: the making of a lenticular galaxy in the Fornax Cluster

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 ...

STELLAR NUCLEI AND INNER POLAR DISKS IN LENTICULAR GALAXIES [PDF]

The Astronomical Journal, 2016
ABSTRACT 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 the Isaac Newton Group.

The lenticular galaxy NGC3607: stellar population, metallicity and ionised gas [PDF]

, 2009
In this work we derive clues to the formation scenario and ionisation source of the lenticular galaxy NGC 3607 by means of metallicity gradients, stellar population and emission lines properties.

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.
