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

On the rotation of elliptical galaxies [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 1978
The tensor virial theorem is applied to models of early-type galaxies. First the theorem is applied to rotating elliptical galaxies whose constant-density surfaces are similar ellipsoids. A relationship is obtained between the observed rotations and the forms of generally triaxial galaxies.

UV fluxes in elliptical galaxies [PDF]

open access: bronzeSymposium - International Astronomical Union, 1997
The key properties of elliptical galaxies are compared to present-day models calling attention on several points of contradiction. The nature of the UV fluxes and their usefulness to cast light on the age-metallicity dilemma are discussed. Finally, preliminary results of an attempt aimed at reconciling theory with observations by means of an new IMF ...

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.

The orientation of elliptical galaxies [PDF]

open access: yesAstrophysics and Space Science, 2010
We determine the orientations of the light distribution of individual elliptical galaxies by combining the profiles of photometric data from the literature with triaxial models. The orientation is given by a Bayesian probability distribution. The likelihood of obtaining the data from a model is a function of the parameters describing the intrinsic ...

On the ellipticity of galaxy clusters [PDF]

open access: yesProceedings of the International Astronomical Union, 2004
We analysed 246 scanned ACO clusters and we do not find any dependence of galaxy cluster ellipticity on redshift.

Gravitational Lensing by Elliptical Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 2002
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).
