Structural and dynamical modeling of WINGS clusters. II. The orbital anisotropies of elliptical, spiral and lenticular galaxies [PDF]

open access: greenAstronomy & Astrophysics, 2019
The orbital shapes of galaxies of different classes are a probe of their formation and evolution. The Bayesian MAMPOSSt mass-orbit modeling algorithm is used to jointly fit the distribution of elliptical, spiral-irregular, and lenticular galaxies in projected phase space, on three pseudo-clusters (built by stacking the clusters after re-normalizing ...

The Mean Ratio of Mass to the Three-Halves Power of Luminosity for Elliptical and Lenticular Galaxies [PDF]

open access: bronzePublications of the Astronomical Society of the Pacific, 1971
The available data on masses of ellipticals and lenticulars are summarized with emphasis on the uncertainties in the ratio R of mass to 10-O.6M, where M is the absolute magnitude. With correction for galactic absorption the result is R= 0. ;2147 'o (and, as a by-product, a mean mass-luminosity ratio of 38-+ based on the magnitude scale in the de ...

Investigating the Correlations between Physical Parameters of Elliptical and Lenticular Galaxies

open access: diamondIraqi Journal of Science
This study aims to investigate the features of stellar-gaseous kinematics and dynamics mass using scaling coefficient relationships (such as the Faber–Jackson relation (FJR)) of two samples of elliptical and lenticular galaxies. These two samples of 80 ellipticals and 97 lenticulars were selected from previous literature works.

A Catalog of the Most Optically Luminous Galaxies at z < 0.3: Super Spirals, Super Lenticulars, Super Post-mergers, and Giant Ellipticals [PDF]

open access: bronzeThe Astrophysical Journal Supplement Series, 2019
We present a catalog of the 1525 most optically luminous galaxies from the Sloan Digital Sky Survey (SDSS) with r-band luminosity L_r > 8L* and redshift z<0.3, including 84 super spirals, 15 super lenticulars, 14 super post-merger galaxies, and 1400 giant ellipticals.

The SAURON project--V. Integral-field emission-line kinematics of 48 elliptical and lenticular galaxies [PDF]

open access: greenMonthly Notices of the Royal Astronomical Society, 2006
We present the emission-line fluxes and kinematics of 48 representative elliptical and lenticular galaxies obtained with our custom-built integral-field spectrograph SAURON. Hb, [OIII], and [NI] emission lines were measured using a new procedure that simultaneously fits both the stellar spectrum and the emission lines.

Dust-lanes in elliptical and lenticular galaxies

open access: gold, 1982
A small proportion of elliptical and lenticular galaxies show evidence of well-defined dust-lanes when examined on deep survey plates. New near-infrared (JHK) observations of 46 dust-lane galaxies are presented and compared with those for a sample of 24 morphologigally normal systems. Infrared excesses are found preferentially in galaxies which exhibit

Early-type galaxy speciation: elliptical (E) and ellicular (ES) galaxies in the Mbh–M*,sph diagram, and a merger-driven explanation for the origin of ES galaxies, antitruncated stellar discs in lenticular (S0) galaxies, and the Sérsicification of E galaxy light profiles

open access: goldMonthly Notices of the Royal Astronomical Society
ABSTRACT In a recent series of papers, supermassive black holes were used to discern pathways in galaxy evolution. By considering the black holes’ coupling with their host galaxy’s bulge/spheroid, the progression of mass within each component has shed light on the chronological sequence of galaxy speciation.
