  1. 1. There and back again... An Earth magneto-tale : understanding plasma flows in the magnetotail

    Author : Alexandre De Spiegeleer; Maria Hamrin; Herbert Gunell; Timo Pitkänen; Colin Forsyth; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma dynamics; Earth magnetosphere; magnetotail; plasma sheet flows; oscillatory flows; burst bulk flows; tailward flows; rymdfysik; Space Physics; rymd- och plasmafysik; Space and Plasma Physics;

    Abstract : On average, the Earth's magnetotail plasma sheet seems to be a calm region of the magnetosphere where the plasma moves slowly towards Earth. However, the plasma sheet actually hosts many phenomena, some of which can affect Earth. READ MORE

  2. 2. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts

    Author : Louis Richard; Yuri V. Khotyaintsev; Daniel B. Graham; Andris Vaivads; Emiliya Yordanova; Vassilis Angelopoulos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma jets; Magnetic reconnection; Particle acceleration; Magnetosphere; Magnetospheric Multiscale; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : High-speed plasma flows (jets) are ubiquitous phenomena in the visible Universe. When the fast plasma flow encounters the ambient plasma at rest, it forms a front where its kinetic energy is dissipated. At the jet front, charged particles gain energy from the electromagnetic fields through heating and acceleration. READ MORE

  3. 3. Auroral electrodynamics of plasma boundary regions

    Author : Sónia Liléo; Göran Marklund; Anders Eriksson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space physics; Rymdfysik;

    Abstract : The electrodynamic coupling between the auroral ionosphere and the magnetosphere is the main subject of this thesis. Satellite measurements of electric and magnetic fields and of charged particles are used to explore three distinct plasma boundaries, magnetically linked to the nightside auroral ionosphere.

  4. 4. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts

    Author : Louis Richard; Yuri V. Khotyaintsev; Tomas Karlsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : High speed plasma flows (jets) are ubiquitous phenomena in the universe. For example, they carry energy from the most powerful sources (e.g active galactic nucleï AGN) to the medium at rest surrounding them. READ MORE

  5. 5. Development and simulated observations of the Jovian Neutrals Analyzer

    Author : Angèle Pontoni; Manabu Shimoyama; Mats Holmström; Ove Andersson; Andrew Yau; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; space instrumentation; space physics; Ganymede; Jupiter; fysik; Physics; rymd- och plasmafysik; Space and Plasma Physics;

    Abstract : This thesis deals with the development of the Jovian Neutrals Analyzer (JNA) for the Jupiter ICy moons Explorer (JUICE) mission to Jupiter, planned to launch in 2023. Jupiter, the largest planet in the Solar System, orbits the Sun at five times the distance from the Earth to the Sun, accompanied by dozens of moons, rings, and the largest object in the SolarSystem: the Jovian magnetosphere.
