Implications and Applications of Kinematic Galaxy Scaling Relations

International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Galaxy scaling relations, which describe a connection between ostensibly unrelated physical characteristics, testify to an underlying order in galaxy formation that requires understanding. I review the development of a scaling relation that (1) unites the well‐known fundamental plane (FP) relation of giant elliptical galaxies and Tully‐Fisher (TF ...

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.

Luminosities of Barred and Unbarred S0 Galaxies

, 2012
Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for objects classified in blue light, and for those that were classified in ...

The APM Bright Galaxy Catalogue [PDF]

, 1995
The APM Bright Galaxy Catalogue lists positions, magnitudes, shapes and morphological types for 14,681 galaxies brighter than $b_J$ magnitude 16.44 over a 4,180 square degree area of the southern sky.

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.

What Are S0 Galaxies?

, 2009
The data collected in the Shapley-Ames catalog of bright galaxies show that lenticular (S0) galaxies are typically about a magnitude fainter than both elliptical (E) and early spiral (Sa) galaxies.

The influence of environment in the formation of lenticular galaxies

, 2021
Lenticular galaxies (S0s) are believed to form through 2 main pathways: mergers or fading of a spiral progenitor. It is not clear yet what is the dominant scenario, nor what are the parameters and physical conditions that favor one path instead of the other. In a pilot study with 21 galaxies (Coccato et al.

The luminosity function of field galaxies

, 2011
Schmidt's method for construction of luminosity function of galaxies is generalized by taking into account the dependence of density of galaxies from the distance in the near Universe.

CDM, Feedback and the Hubble Sequence [PDF]

, 2002
We have performed TreeSPH simulations of galaxy formation in a standard LCDM cosmology, including effects of star formation, energetic stellar feedback processes and a meta-galactic UV field, and obtain a mix of disk, lenticular and elliptical galaxies ...

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 ...
