The mass-to-charge ratio scale

On The Mass-to-Light Ratio of Large Scale Structure

We examine the dependence of the mass-to-light (M/L) ratio of large-scale structure on cosmological parameters, in models that are constrained to match observations of the projected galaxy correlation function wp(rp) and the galaxy luminosity function. For a sequence of cosmological models with a fixed, observationally motivated power spectrum shape and increasing normalization σ8, we find para...

Solutions to the Lorentz Force Equation with Fixed Charge-to-mass Ratio in Globally Hyperbolic Spacetimes

We obtain an extension of the classical Avez-Seifert theorem, for trajectories of charged test particles with fixed charge-to-mass ratio. In particular, given two events x0 and x1, with x1 in the chronological future of x0, we find an interval I =]− R, R[ such that for any q/m ∈ I there is a timelike connecting solution of the Lorentz force equation.

On the Charge to Mass Ratio of Neutron Cores and Heavy Nuclei

We determine theoretically the relation between the total number of protons Np and the mass number A (the charge to mass ratio) of nuclei and neutron cores with the model recently proposed by Ruffini et al. (2007) and we compare it with other Np versus A relations: the empirical one, related to the Periodic Table, and the semi-empirical relation, obtained by minimizing the Weizsäcker mass formu...

Charge-to-mass Ratio of Saltating Particles in Wind-Blown Sand

The electrification of sand particles plays an important role in aeolian events. In this paper, the charge-to-mass ratio vertical profiles of saltating particles in wind-blown sand were measured by a field experiments. By combining the results of field measurements with our previous wind-tunnel measurements, we discussed the factors affecting the charge-to-mass ratio of saltating particles. It ...
