The core fundamental plane of B2 radio galaxies

, 2009
The photometric, structural and kinematical properties of the centers of elliptical galaxies, harbor important information of the formation history of the galaxies.

Velocity dispersions and mass-to-light ratios for elliptical galaxies.

, 1976
The close correlation between luminosity and dynamical properties for normal ellipticals is further evidence that the ellipticals are very nearly a one-parameter family with total mass as the most important independent variable. (AIP)

Searching for tidal tails - investigating galaxy harassment

, 2005
Galaxy harassment has been proposed as a physical process that morphologically transforms low surface density disc galaxies into dwarf elliptical galaxies in clusters.

Fundamental Properties of Elliptical Galaxies

, 1987
The global properties of elliptical galaxies, such as luminosity, radius, projected velocity dispersion, projected luminosity, etc., form a two-dimensional family.

MINOR MERGERS AND THE SIZE EVOLUTION OF ELLIPTICAL GALAXIES [PDF]

, 2009
Using a high-resolution hydrodynamical cosmological simulation of the formation of a massive spheroidal galaxy we show that elliptical galaxies can be very compact and massive at high redshift in agreement with recent observations.

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

The habitability of large elliptical galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT Based on numbers of stars, supernova rates, and metallicity, a prior study concluded that large elliptical galaxies contain up to 10 000 times more habitable planets than the Milky Way and are thus the ‘cradles of life’. Using the results of their model and taking into account galactic number distributions and supernova rates, I

The Extremely Low Mechanical Force Generated by Nano‐Pulling Induces Global Changes in the Microtubule Network, Nuclear Morphology, and Chromatin Transcription in Neurons

Small, EarlyView.
Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...

UV Visibility of Moderate-Redshift Giant Elliptical Galaxies [PDF]

Journal of Astronomy and Space Sciences, 1998
We show quantitatively whether giant elliptical galaxies would be visible at far UV wavelengths if they were placed at moderate redshift of 0.4-0.5. On the basis of simple cosmological tests, we conclude that giant elliptical galaxies can be detectable ...

Dust in Hot Plasma of Nearby Dusty Elliptical Galaxies Observed with the Spitzer Space Telescope [PDF]

, 2006
We report on mid- and far-IR Spitzer observations of 7 nearby dusty elliptical galaxies by using the Multiband Imaging Photometer (MIPS) and Infrared Spectrograph (IRS).
