It studies various aspects of this useful quantity and its ability to tell us about the Universe. These include an examination of the accuracy of its approximation in the flat-sky regime, an analysis of the reapportioning of power to its low multipoles as a result of narrow redshift window functions, and an investigation of a new observable based on fluctuations in redshift instead of density, and its effectiveness in constraining cosmological parameters.</p> Dewey 500.2 37 Département de physique théorique 133 false 795 Groupe Durrer 292098f5-b1df-4188-b896-09ef2b2107cd Thesis Public main.pdf 10198804 application/pdf 7e56da55f3793d57e8f81da709fd49240fc0e56abadb27aaf14d2cc187be1853 571f452f-d58c-4aac-965c-7299e9bd1b18 Imprimatur Public 20230803144441300(1).PDF 326784 application/pdf 9f30fc93d8e9f25260e73ab86fbd0a5665f1ba182efdfe9d5d339ec5cc90112a openAccess Faculté des sciences / Section de physique / Département de physique théorique
