It explores the observational consequences of the second-order vector mode, and addresses magnetic field generation and the weak lensing signatures, which are key phenomena of the vector mode. The author demonstrates that the second-order vector mode, which never appears at the linear-order level, naturally arises from the non-linear coupling of the first-order scalar modes. This leads to the remarkable statement that the vector-order mode clearly contributes to the generation of cosmological magnetic fields. Moreover, the weak lensing observations are shown to be accessible to the vector mode. On the basis of ongoing and forthcoming observations, the thesis concludes that the second-order vector mode is detectable. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aCosmology 606 $aAstrophysics 606 $aGravitation 606 $aCosmology$3https://scigraph.springernature.com/ontologies/product-market-codes/P22049 606 $aAstrophysics and Astroparticles$3https://scigraph.springernature.com/ontologies/product-market-codes/P22022 606 $aClassical and Quantum Gravitation, Relativity Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P19070 615 0$aCosmology. 615 0$aAstrophysics. 615 0$aGravitation. 615 14$aCosmology. 615 24$aAstrophysics and Astroparticles. 615 24$aClassical and Quantum Gravitation, Relativity Theory. 676 $a521.4 700 $aSaga$b Shohei$4aut$4http://id.loc.gov/vocabulary/relators/aut$0835970 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910300548703321 996 $aThe Vector Mode in the Second-order Cosmological Perturbation Theory$92541122 997 $aUNINA
