Chaos and Elliptical Galaxies [PDF]

open access: yesCELESTIAL MECHANICS AND DYNAMICAL ASTRONOMY, 1995
Recent results on chaos in triaxial galaxy models are reviewed. Central mass concentrations like those observed in early-type galaxies -- either stellar cusps, or massive black holes -- render most of the box orbits in a triaxial potential stochastic ...

Cold gas in elliptical galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2001
We explore the evolution of the cold gas (molecular and neutral hydrogen) of elliptical galaxies and merger remnants ordered into a time sequence on the basis of spectroscopic age estimates.

Compact Elliptical Galaxies [PDF]

open access: bronzeSymposium - International Astronomical Union, 1987
We summarize our present knowledge on low-mass high-surface brightness elliptical objects near massive galaxies that are often called M32-type or compact elliptical galaxies. The origin of the low mass of these objects is a controversial matter: is it intrinsic to their formation or produced, as classically believed, by tidal stripping from the massive

The Relationship between Slope and Luminosity [PDF]

open access: yesKirkuk Journal of Science, 2010
In this study, a sample of galaxies has been adopted. It consists of 112 elliptical galaxies, among them were 56 dwarf elliptical galaxies, which belong to virgo cluster, 37 normal galaxies and 19 bright galaxies. Also, surface brightness profiles fitted

Retracted: Can the chemical industry solve the climate change?On the role of human energy production, renewable energies, and the potential of chemistry as a solution provider

open access: yesChemie Ingenieur Technik, EarlyView., 2023
Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

Deviations of the Surface Brightness Distribution in Isolated Elliptical Galaxies [PDF]

open access: yesمجلة التربية والعلم, 2012
In this paper, we present the surface brightness profiles of 48 isolated elliptical galaxies. we have adopted the r1/n – law to the observed surface brightness profiles of the adopted sample of isolated elliptical galaxies for the intermediate radial ...

The Fate of the Interstellar Medium in Early-type Galaxies. II. Observational Evidence for Morphological Quenching

open access: yesThe Astrophysical Journal, 2023
The mechanism by which galaxies stop forming stars and get rid of their interstellar medium (ISM) remains elusive. Here, we study a sample of more than 2000 elliptical galaxies in which dust emission has been detected.
