The Physical Origin of the Fundamental Plane (of Elliptical Galaxies)

, 1997
I review the basic problems posed by the existence of the Fundamental Plane, and discuss its relations with the Virial Theorem (VT). Various possibilities are presented that can produce the observed uniform departure from homology (structural, dynamical) and/or from a constant stellar mass-to-light ratio. The role of orbital anisotropy and its relation

The Near-Infrared Fundamental Plane of Elliptical Galaxies and Its Evolution

, 1997
We present the first Fundamental Plane (FP) that has been constructed in the K—band using near—infrared imaging source data. The slope of this IR FP differs systematically both from the optical relation and the virial expectation (assuming homology and constant M/L) in a way that cannot be explained by stellar populations effects alone.

The fundamental plane of brightest cluster galaxies and isolated elliptical galaxies

Astrophysics and Space Science, 2020
This work aims to investigate the fundamental plane, the Kormendy, the Faber-Jackson, and the size-luminosity relations for two galaxy samples (brightest cluster galaxies (BCGs) and isolated elliptical galaxies (IEs)) in different environments. These relations are investigated in different wavelength bands, griz, of the Sloan Digital Sky Survey (SDSS).

Stellar systems following the R^1/m^ luminosity law. II. Anisotropy, velocity profiles, and the fundamental plane of elliptical galaxies.

, 1997
Following a first paper on this subject (Ciotti 1991, hereafter Paper I), we study the dynamical properties of spherical galaxies with surface luminosity profile described by the R1/m-law, in which a variable degree of orbital anisotropy is allowed. The parameter m for the present models covers the range [1, 10].

Elliptical Galaxies and the Thickness of the Fundamental Plane

1992
Re-analysis and comparison of the data presented in Dressier et al. (1978: 7S) and Djorgovski and Davis (1987: DD) lead to the following generic representation of the fundamental plane: 10 log(σ) = (1 + 2β)M t + e +cst, where M t is the absolute magnitude and e then mean surface brightness (in mags) within the effective radius; we have adopted: M/L
