Fundamental Plane of Elliptical Galaxies in f(R) Gravity: The Role of Luminosity [PDF]

open access: greenAtoms, 2018
The global properties of elliptical galaxies are connected through the so-called fundamental plane of ellipticals, which is an empirical relation between their parameters: effective radius, central velocity dispersion and mean surface brightness within ...

Constraining theories of gravity by fundamental plane of elliptical galaxies [PDF]

open access: greenarXiv, 2020
We show that fundamental plane of elliptical galaxies can be used to obtain observational constraints on metric theories of gravity. Being it connected to global properties of ellipticals, it can fix parameters of modified gravity. Specifically, we use fundamental plane to constrain modified theories of gravity with Yukawa-like corrections which ...

Red Mergers and the Assembly of Massive Elliptical Galaxies: the Fundamental Plane and its Projections [PDF]

open access: bronzeMon.Not.Roy.Astron.Soc.369:1081-1089,2006, 2006
Several recent observations suggest that gas-poor (dissipationless) mergers of elliptical galaxies contribute significantly to the build-up of the massive end of the red sequence. We perform a series of major merger simulations to investigate the spatial and velocity structure of the remnants of such mergers.

Investigation of the Fundamental Plane Relationship For the Evolution of the Elliptical and Lenticular Galaxies [PDF]

open access: goldمجلة التربية والعلم
The Fundamental Plane relates the effective radius and surface brightness of an early-type galaxy to its velocity dispersion. It is important in understanding galaxy formation and evolution processes. The present work aims to investigate this relation as

The Fundamental Plane of Elliptical Galaxies in Compact Groups [PDF]

open access: bronzeAstrophys.Space Sci. 285 (2003) 79-84, 2001
We present a study focusing on the nature of compact groups through the study of their elliptical galaxies. We determine velocity dispersions ($\sigma$) for 18 18 bright elliptical galaxies located in the core of Hickson compact groups and a control sample of 12 bright bona fide ellipticals located in the field or very loose groups.

Mergers in Galaxy Groups. II. The Fundamental Plane of Elliptical Galaxies [PDF]

open access: green, 2014
Observations consistently show that elliptical galaxies follow a tight "fundamental plane" scaling relation between size, mean surface brightness and velocity dispersion, with the form $R \propto \sigma^{a}\mu^{b}$. This relation not only has very small (<0.05 dex) intrinsic scatter, but also has significantly different coefficients from the expected ...

The Fate of Cannibalized Fundamental‐Plane Elliptical Galaxies [PDF]

open access: bronze, 1997
Evolution and disruption of galaxies orbiting in the gravitational field of a larger cluster galaxy are driven by three coupled mechanisms: (1) tidal heating due to its time-dependent motion in the primary; (2) mass loss due to the tidal strain field ...

MOND and the fundamental plane of elliptical galaxies [PDF]

open access: greenarXiv, 2003
It is shown that the MOdified Newtonian Dynamics (MOND) explains the tilt of the fundamental plane of elliptical galaxies without the need of non-baryonic dark matter. Results found for elliptical galaxies extends to globular clusters and galaxy clusters, showing that MOND agrees with observations over 7 order of magnitude in acceleration.

Effect of the Environment on the Fundamental Plane of Elliptical Galaxies [PDF]

open access: greenarXiv, 2000
We present an analysis of interacting E/S0 galaxies location on the Fundamental Plane. Using the NEMO package, we performed N-body simulations of close encounters and mergers between two spherical galaxies. We followed how structural and dynamical parameters (central density, half-mass radius and velocity dispersion)of galaxies are changed during the ...

The properties of field elliptical galaxies at intermediate redshift - III. The Fundamental Plane and the evolution of stellar populations fromz≈0.4toz=0 [PDF]

open access: bronze, 2001
We report on the study of a sample of 25 field early-type galaxies, in the redshift range z≈0.1–0.5, selected on the basis of colours and morphology from the Medium Deep Survey (MDS) of the Hubble Space Telescope (HST). Surface photometry in two colours (
