The ‘Photometric Plane’ of elliptical galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 The Sersic r^(1/n) index n of an elliptical galaxy (or bulge) has recently been shown to correlate strongly (r=0.8) with a galaxy's central velocity dispersion. This index could therefore prove extremely useful and cost-effective (in terms of both telescope time and data reduction) for many fields of extragalactic research.

The Globular Cluster System of the Galaxy NGC 6876
Galaxies, 2017 We present preliminary results of the deep photometric study of the elliptical galaxy NGC 6876, located at the center of the Pavo group, and its globular cluster system.

Tracing Galaxy Evolution by Their Present-Day Luminosity Function
Open Astronomy, 2011 Galaxy luminosity functions are derived for different morphological types and various colors of galaxies, to trace the evolutionary effects which a priori should be different for void and supercluster galaxies.

ABSORPTION LINE GRADIENTS IN THE SPECTRUM OF AN ELLIPTICAL GALAXY NGC 5864A [PDF]
Journal of Astronomy and Space Sciences, 1999 The archival long-slit spectra, covering the wavelength range 4050 ~ 5150 Å, have been used to investigate the radial behavior of absorption line fea-tures (G4300, Fe4383, Ca4455, Fe4531, and Hβ) of an elliptical galaxy NGC 5846A.

THE ELLIPTICITIES OF GALAXIES IN GALAXY CLUSTERS OF DIFFERENT MORPHOLOGICAL TYPE
Odessa Astronomical Publications, 2014 The distribution of galaxy ellipticities was analyzed for 207 rich PF galaxy clusters found in the Munster Red Sky Survey Galaxy Catalogue. Clusters with BM types from a comparison with the ACO catalogue were also classified on the new scheme.

Deep MOS Spectroscopy of NGC 1316 Globular Clusters
Galaxies, 2017 The giant elliptical galaxy NGC 1316 is the brightest galaxy in the Fornax cluster, and displays a number of morphological features that might be interpreted as an intermediate age merger remanent (∼3 Gyr).

Gravitational Lensing by Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 2005 The probability that high-redshift quasars are gravitationally-lensed by intervening galaxies increases rapidly with the cosmological constant, ΩΛ0 (whilst being only weakly dependent on the density parameter, Ωm0), and the low number of lenses observed implies that ΩΛ0 ≲ 0.7 (e.g. Kochanek 1996).

Surface Photometry of Spiral Galaxy NGC 5005 and Elliptical Galaxy NGC 4278
مجلة بغداد للعلوم, 2018 Two galaxies have been chosen, spiral galaxy NGC 5005 and elliptical galaxy NGC 4278 to study their photometric properties by using surface photometric techniques with griz-Filters. Observations are obtained from the Sloan Digital Sky Survey (SDSS).

Galaxy Merging and the Fundamental Plane of Elliptical Galaxies [PDF]
, 2006 We present preliminary results of numerical simulations of dissipationless merging of stellar systems, aimed at exploring the consequences of merging between gas free, spheroidal systems. In particular, we study the dynamical and structural characteristics of hierarchical merging between equal mass stellar systems, and we compare the properties of the ...
