Dispersive Properties of MHD Waves in the Expanding Solar Wind for a Parker Spiral Geometry
Sebastián Saldivia, Felipe Asenjo, Pablo S. Moya
In this work, we quantify the effects of solar wind expansion on the dispersive properties of the three normal modes of ideal MHD using the Expanding Box Model, under a background…

Laser-Driven Annular Shock Waves as Laboratory Analogues of CDM Cosmologies and Cosmological Gravitational Waves
Felipe A. Asenjo, Felipe Veloso, Julio C. Valenzuela
We demonstrate that the experimental evolution of an annular, laser-driven plasma shock wave, expanding over time and undergoing self-interaction gives rise to multiple shock struc…

Electromagnetic plasma waves in Big Bounce and Big Crunch cosmologies
Felipe A. Asenjo
We study the exact dynamics of electromagnetic waves in cold electron-positron plasma in the simplest background of Big Bounce and Big Crunch cosmologies. We show that these waves…
