Recent research shows that the cosmological components of the Universe should influence
on the propagation of GravitationalWaves (GWs) and even it has been proposed
a new way to measure the cosmological constant using Pulsar Timing Arrays (PTAs).
However, these results have considered very particular cases (e.g. a de Sitter Universe
or a mixing with non-relativistic matter). In this work...

In this work, we present the thermodynamic
study of amodel that considers the black hole as a condensate
of gravitons. In this model, the spacetime is not asymptotically
flat because of a topological defect that introduces an
angle deficit in the spacetime like in Global Monopole solutions.
We have obtained a correction to the Hawking temperature
plus a negative pressure associated with...

108. Angular distribution of Auger electrons following electron-impact excitation of highly charged Be-like ions

Electron-impact excitation (EIE) of atoms and ions is one of fundamental processes in astrophysical and laboratory plasmas. Chen et al. [1] studied the relativistic effect on the angular distribution of Auger electrons following EIE of Be-like ions. However, as a main part of the relativistic effect, the Breit interaction on the angular distribution was not considered. In this work [2], we...
