Density variations in the NW star stream of M31

The number density of scalar dark matter particles would then be produced in the early stages of the Universe, by a freeze-in mechanism due to its very feeble coupling to the

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 ,

VI, a discussion of the spatial spin density of the Majorana wave function in the various types of inhomogeneous nanowires as a function of their smoothness.. This will allow us to

In the “big picture” perspective of the recent years that we have described in Brazil, Spain, Portugal and Puerto Rico there are some similarities and important differences,

Numerical simulations accounting for the gravitational evolution of billions of dark matter particles confirm that the cold dark matter model is consistent, at least on large

The density distribution of sources detected in at least one IRAC channel has been analyzed as a function of the distance from the cluster center (panel (A) of Figure 5).. The

In order to elucidate this behavior of the probability density function for the ionization energy, we compare the radial function of the initial confined state with those of

In this work we deal with the problem of the trajectories corresponding to a functional whose Lagragian density is linear in the torsion function of the particle worldline trajectory
