  1. 1. Electron energization in near-Earth space Studies of kinetic scales using multi-spacecraft data

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elin Eriksson; Uppsala universitet.; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic reconnection; electron acceleration; electron heating; magnetosheath; magnetotail; magnetic nulls; Cluster; Magnetospheric MultiScale; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Plasma, a gas of charged particles exhibiting collective behavior, is everywhere in the Universe. The heating of plasma to millions of degrees and acceleration of charged particles to very high energies has been observed in many astrophysical environments. How and where the heating and acceleration occur is in many cases unclear. READ MORE

  2. 2. Ion dynamics and structure of collisionless shocks

    University dissertation from Uppsala University

    Author : Andreas Johlander; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Shock waves are responsible for slowing down and heating supersonic flows. In collisionless space plasmas, shocks are able to accelerate particles to very high energies. We study injection of suprathermal ions at Earth’s quasi- parallel shock using high time resolution data from the Cluster spacecraft. READ MORE

  3. 3. 3D Magnetic Nulls and Regions of Strong Current in the Earth's Magnetosphere

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Elin Eriksson; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetic Nulls; Particle Acceleration; Current sheets; Magnetic reconnection; Magnetosphere; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Plasma, a gas of charged particles exhibiting collective behaviour, can be found everywhere in our vast Universe. The characteristics of plasma in very distant parts of the Universe can be similar to characteristics in our solar system and near-Earth space. READ MORE

  4. 4. Ion dynamics and structure of collisionless shocks in space

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andreas Johlander; Uppsala universitet.; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Shock waves form when supersonic flows encounter an obstacle. Like in regular gases, shock waves can form in a plasma - a gas of electrically charged particles. Shock waves in plasmas where collisions between particles are very rare are referred to as collisionless shock waves. READ MORE

  5. 5. Electron-scale physics in space plasma Thin boundaries and magnetic reconnection

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Cecilia Norgren; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Most of the observable Universe consists of plasma, a kind of ionized gas that interacts with electric and magnetic fields. Large volumes of space are filled with relatively uniform plasmas that convect with the magnetic field. READ MORE
