Figure

Figure 1. The EPIC 0.5–2 keV exposure-corrected and particle- particle-background-subtracted image of SL2S J08544
Figure 2. pn spectrum extracted from a 1.5 arcmin aperture: all the back- back-ground components, instrumental and cosmic have been modelled and the source component is shown by the solid red line
Figure 3. Composite CFHTLS g,r,i colour image of the group SL2S J08544-0121, with a size of 3 × 2 arcmin corresponding to 891 kpc × 594 kpc at the redshift of the object, z = 0.351

3. Estimate the physical properties of the system: mass density slope of the lens galaxy γ, projected dark matter mass fraction within the Einstein radius M dark /M lens ,

Mass scale sets radius of tangential critical curve, which is approximately the location of tangential arcs.. 3 dimensional mass density

There is already a considerable amount of evidence that bright galaxies contain large amounts of dark matter, often ten times more than the mass of all their stars put together..

With regard to bone parameters it can be seen that there is a clearly significant difference in the experimental group both in terms of degree of bone mass loss, significantly

The remarkable selectivity, stability, and high current density of CoFePB, in contrast to state-of-the-art catalysts based on platinum-group metals (PGM), is an important step in

In the context of galaxy formation, two fundamental properties are given by the underlying dark matter structure: the distribution of their masses at a certain redshift as the halo

The lightest neutralino, ˜ χ 0 1 , is usually assumed to be the LSP, unless R-parity is not conserved, because it is the only MSSM particle which can make a good cold dark

We use Lenstool to model the gravitational lensing, which is near to a “fold arc” configuration for an elliptical mass distribution of the central halo, where four images of the
