Photometric investigations of NGC 2577 and NGC 4310 Lenticular Galaxies
Iraqi Journal of Science, 2018 In this study, two lenticular galaxies ( NGC 2577, NGC 4310 ) have been chosen to study their morphological and photometric properties, by using The [1] IRAF ISOPHOTE ELLIPSE task with griz -Filters.

Stellar Populations in Nearby Lenticular Galaxies
The Astrophysical Journal, 2006 We have obtained 2D spectral data for a sample of 58 nearby S0 galaxies with the Multi-Pupil Spectrograph of the 6m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. The Lick indices H-beta, Mgb, and are calculated separately for the nuclei and for the bulges taken as the rings between R=4" and 7"; and the ...

The total mass of the early-type galaxy NGC 4649 (M60) [PDF]
Serbian Astronomical Journal, 2008 In this paper the problem of the total mass and the total mass-to-light ratio of the early-type galaxy NGC 4649 (M60) is analyzed. Use is made of two independent techniques: the X-ray methodology which is based on the temperature of the X-ray halo of NGC

The SAURON project - IV. The mass-to-light ratio, the virial mass estimator and the Fundamental Plane of elliptical and lenticular galaxies [PDF]
, 2005 We investigate the well-known correlations between the dynamical mass-to-light ratio M/L and other global observables of elliptical (E) and lenticul ar (S0) galaxies.

Measurement of the Lick indices in early-type galaxies: Line-of-sight velocity distribution corrections for IC 1459 [PDF]
Serbian Astronomical Journal, 2009 In this paper we analyze the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use the long-slit spectra of the elliptical galaxy IC 1459 from which its kinematics had previously been extracted to calculate ...

Angular Momentum across the Hubble sequence from the CALIFA survey [PDF]
, 2014 We investigate the stellar angular momentum of galaxies across the Hubble sequence from the CALIFA survey. The distribution of CALIFA elliptical and lenticular galaxies in the $\lambda_{\rm Re}-\epsilon_{\rm e}$ diagram is consistent with that shown by the Atlas$^\mathrm{3D}$ survey.

The SLUGGS survey: Using extended stellar kinematics to disentangle the formation histories of low mass S0 galaxies [PDF]
, 2017 We utilise the DEIMOS instrument on the Keck telescope to measure the wide-field stellar kinematics of early-type galaxies as part of the SAGES Legacy Unifying Globulars and GalaxieS (SLUGGS) survey. In this paper, we focus on some of the lowest stellar mass lenticular galaxies within this survey, namely NGC 2549, NGC 4474, NGC 4459 and NGC 7457 ...

CENTRAL STELLAR MASS DEFICITS IN THE BULGES OF LOCAL LENTICULAR GALAXIES, AND THE CONNECTION WITH COMPACT z ∼ 1.5 GALAXIES [PDF]
, 2013 We have used the full radial extent of images from the Hubble Space Telescope's Advanced Camera for Surveys and Wide Field Planetary Camera 2 to extract surface brightness profiles from a sample of six, local lenticular galaxy candidates. We have modeled

The SLUGGS survey: chromodynamical modelling of the lenticular galaxy NGC 1023 [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Globular clusters (GCs) can be considered discrete, long-lived, dynamical tracers that retain crucial information about the assembly history of their parent galaxy. In this paper, we present a new catalogue of GC velocities and colours for the lenticular galaxy NGC 1023, we study their kinematics and spatial distribution, in comparison with the ...

Understanding the Fundamental Plane and the Tully Fisher Relation
Frontiers in Astronomy and Space Sciences, 2020 The relation between early type galaxy size, surface brightness and velocity dispersion, “the fundamental plane,” has long been understood as resulting from equilibrium in their largely pressure supported stellar dynamics.
