All mathematical developments are completed by illuminating physical interpretations, and the thesis, which is guided by existing observations, is purely theoretical. In part I, the author further develops a magnetogenesis model proposed in the literature, providing an unprecedented level of physical understanding. He demonstrates that the physics of photoionisation is very likely to have premagnetised, at a relevant level, the entire Universe at the early epoch of the formation of the first luminous sources. In part II, the author adapts the tools of plasma spectral theory to the context of gravitational instability of the baryonic gas within the stratified structures of the Cosmic Web. He skillfully derives the wave equation governing the growth of perturbations and explores various equilibrium configurations, in planar and cylindrical geometries characteristic of cosmic walls and filaments, for isothermal and polytropic conditions, with or without an external gravitational background. Clearly structured and written in pedagogical style, this outstanding thesis puts the results into perspective and highlights the merits and limitations of the various approaches explored. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aAstrophysics 606 $aPlasma (Ionized gases) 606 $aCosmology 606 $aMagnetism 606 $aMagnetic materials 606 $aGravitation 606 $aNuclear physics 606 $aAstrophysics and Astroparticles$3https://scigraph.springernature.com/ontologies/product-market-codes/P22022 606 $aPlasma Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P24040 606 $aCosmology$3https://scigraph.springernature.com/ontologies/product-market-codes/P22049 606 $aMagnetism, Magnetic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/P25129 606 $aClassical and Quantum Gravitation, Relativity Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P19070 606 $aParticle and Nuclear Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P23002 615 0$aAstrophysics. 615 0$aPlasma (Ionized gases). 615 0$aCosmology. 615 0$aMagnetism. 615 0$aMagnetic materials. 615 0$aGravitation. 615 0$aNuclear physics. 615 14$aAstrophysics and Astroparticles. 615 24$aPlasma Physics. 615 24$aCosmology. 615 24$aMagnetism, Magnetic Materials. 615 24$aClassical and Quantum Gravitation, Relativity Theory. 615 24$aParticle and Nuclear Physics. 676 $a523.01 700 $aDurrive$b Jean-Baptiste$4aut$4http://id.loc.gov/vocabulary/relators/aut$0818689 906 $aBOOK 912 $a9910254575703321 996 $aBaryonic Processes in the Large-Scale Structuring of the Universe$91825212 997 $aUNINA
