    • Alternative high plasma beta regimes of electron heat-flux instabilities in the solar wind 
      López, R. A.; Lazar, M.; Shaaban, S. M.; Poedts, S.; Moya Fuentes, Pablo (IOP Publishing, 2020)
      Heat transport in the solar wind is dominated by suprathermal electron populations, i.e., a tenuous halo and a field-aligned beam/strahl, with high energies and antisunward drifts along the magnetic field. Their evolution ...
    • Applying the horizontal visibility graph method to study irreversibility of electromagnetic turbulence in ... 
      Acosta Tripailao, Belén; Pastén Guzmán, Denisse; Moya Fuentes, Pablo (MDPI, 2021)
      One of the fundamental open questions in plasma physics is the role of non-thermal particles distributions in poorly collisional plasma environments, a system that is commonly found throughout the Universe, e.g., the solar ...
    • Effects of the background turbulence on the relaxation of ion temperature anisotropy in space plasmas 
      Moya Fuentes, Pablo; Navarro, Roberto E. (Frontiers Media, 2021)
      Turbulence in space plasmas usually exhibits two regimes separated by a spectral break that divides the so called inertial and kinetic ranges. Large scale magnetic fluctuations are dominated by non-linear MHD wave-wave ...
    • Electromagnetic electron cyclotron instability in the solar wind 
      Lazar, M.; Yoon, P. H.; Lopez, R. A.; Moya Fuentes, Pablo (American Geophysical Union, 2018)
      The abundant reports on the existence of electromagnetic high-frequency fluctuations in space plasmas have increased the expectations that theoretical modeling may help understand their origins and implications (e.g., ...
    • Feasibility of Ion-cyclotron Resonant Heating in the Solar Wind 
      Navarro, Roberto E.; Muñoz Gálvez, Víctor; Valdivia Hepp, Juan; Moya Fuentes, Pablo (IOP Publishing, 2020)
      Wave-particle interactions are believed to be one of the most important kinetic processes regulating the heating and acceleration of solar wind plasma. One possible explanation for the observed preferential heating of alpha ...
    • Linear kinetic waves in plasmas described by Kappa Distributions 
      Viñas, A. F.; Gaeltzer, R.; Moya Fuentes, Pablo; Mace, R.; Araneda, J. A. (Elsevier, 2017)
      In this chapter we present an overview of the excitation, propagation, and absorption of linear plasma waves in collisionless, spatially uniform, multicomponent, magnetized non-Maxwellian plasma characterized by a ...
    • Magnetic fluctuations in anisotropic space plasmas: The effect of the plasma environment 
      Valdivia Hepp, Juan; Toledo Cabrera, Benjamín; Gallo, N.; Muñoz Gálvez, Víctor; Rogan Castillo, José; Stepanova, M.; Moya Fuentes, Pablo; Navarro, R. E.; Viñas, A. F.; Araneda, J.; López, R. A.; Díaz, M. (Elsevier, 2016)
      The observations in the solar wind, which are usually organized in a beta-anisotropy diagram, seem to be constrained by linear instability thresholds. Unexpectedly, under these quasi-stable conditions, there is a finite ...
    • On the confinement of ultrarelativistic electron remnant belts to low L shells 
      Pinto, V. A.; Zhang, X. J.; Mourenas, D.; Bortnik, J.; Artemyev, A. V.; Lyons, L. R.; Moya Fuentes, Pablo (Wiley, 2020)
      Ultrarelativistic electron remnant belts are frequently observed at low L shells between the inner belt and a re-forming outer belt following geomagnetic disturbances that led to a dropout of electron fluxes at higher ...
    • On the effect of geomagnetic storms on relativistic electrons in the outer radiation belt: Van Allen probes ... 
      Moya Fuentes, Pablo; Pinto, Victor A.; Sibeck, David G.; Kanekal, Shrikanth G.; Baker, Daniel N. (American Geophysical Union, 2017)
      Using Van Allen Probes Energetic Particle, Composition, and Thermal Plasma-Relativistic Electron-Proton Telescope (ECT-REPT) observations, we performed a statistical study on the effect of geomagnetic storms on relativistic ...
    • Outstanding questions in magnetospheric plasma physics: The pollenzo view 
      Borovsky, Joseph E.; Delzanno, Gian Luca; Valdivia Hepp, Juan; Moya Fuentes, Pablo; Stepanova, Marina; Birn, Joachim; Blum, Lauren W.; Lotko, William; Hesse, Michael (Elsevier, 2020)
      Based on discussions held at a workshop in Bra-Pollenzo, Italy, this paper elaborates upon 19 outstanding questions of plasma physics in the Earth’s magnetosphere. The questions are grouped according to (a) driving processes, ...
    • Relativistic Cyclotron Instability in Anisotropic Plasmas 
      López, Rodrigo A.; Moya Fuentes, Pablo; Navarro, Roberto; Araneda, Jaime; Muñoz Gálvez, Víctor; Viñas, Adolfo; Valdivia Hepp, Juan (IOP, 2016)
      A sufficiently large temperature anisotropy can sometimes drive various types of electromagnetic plasma micro-instabilities, which can play an important role in the dynamics of relativistic pair plasmas in space, astrophysics, ...
