The SAURON project - XVI. On the sources of ionization for the gas in elliptical and lenticular galaxies [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2010
Following our study on the incidence, morphology and kinematics of the ionised gas in early-type galaxies we now address the question of what is powering the observed nebular emission. To constrain the likely sources of gas excitation, we resort to a variety of ancillary data, draw from complementary information on the gas kinematics, stellar ...

The Surface Brightness Fluctuations and Globular Cluster Populations of Virgo Elliptical and Lenticular Galaxies [PDF]

open access: bronzePublications of the Astronomical Society of the Pacific, 2000
The Virgo Cluster of galaxies is a complex system composed of several subclusters or ““ clouds.II Our understanding of this structure is severely limited by the small number of member galaxies for which high-precision distance measurements are available.

The Dynamical Distinction between Elliptical and Lenticular Galaxies in Distant Clusters: Further Evidence for the Recent Origin of S0 Galaxies [PDF]

open access: greenThe Astrophysical Journal, 2007
We examine resolved spectroscopic data obtained with the Keck II telescope for 44 spheroidal galaxies in the fields of two rich clusters, Cl0024+16 (z=0.40) and MS0451-03 (z=0.54), and contrast this with similar data for 23 galaxies within the redshift interval 0 ...

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.

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 ...

FURTHER EVIDENCE FOR LARGE CENTRAL MASS-TO-LIGHT RATIOS IN EARLY-TYPE GALAXIES: THE CASE OF ELLIPTICALS AND LENTICULARS IN THE A262 CLUSTER [PDF]

open access: bronzeThe Astronomical Journal, 2012
We present radially resolved spectroscopy of 8 early-type galaxies in Abell~262, measuring rotation, velocity dispersion, $H_3$ and $H_4$ coefficients along three axes, and line-strength index profiles of Mg, Fe and H$ $. Ionized-gas velocity and velocity dispersion is included for 6 galaxies.

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.
