This truly ground-breaking work puts the study of modified gravity models on the same footing as the standard model of cosmology. Since the discovery of the accelerating expansion of the Universe, marked by the awarding of the 2011 Nobel Prize in Physics, there has been a growing interest in understanding what drives that acceleration. One possible explanation lies in theories of gravity beyond Einstein?s General Relativity. This thesis addresses all aspects of the problem, an approach that is crucial to avoiding potentially catastrophic biases in the interpretation of upcoming observational missions. . 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aGravitation 606 $aCosmology 606 $aClassical and Quantum Gravitation, Relativity Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P19070 606 $aCosmology$3https://scigraph.springernature.com/ontologies/product-market-codes/P22049 615 0$aGravitation. 615 0$aCosmology. 615 14$aClassical and Quantum Gravitation, Relativity Theory. 615 24$aCosmology. 676 $a530.11 700 $aBarreira$b Alexandre$4aut$4http://id.loc.gov/vocabulary/relators/aut$0814111 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910254622103321 996 $aStructure Formation in Modified Gravity Cosmologies$91818752 997 $aUNINA
