My PhD

Bayesian large-scale structure inference and cosmic web analysis

After three years' work in the group of Prof. Benjamin Wandelt, I defended my PhD thesis on September 24th, 2015 at the Institut d'Astrophysique de Paris. In its report, the jury underlines in particular the "exceptionally strong scientific content of this PhD, which pushes forward the state of the art". The jury was composed of

Prof. Bertrand Laforge (président du jury),
Prof. Benjamin Wandelt (directeur de thèse),
Prof. Oliver Hahn (rapporteur),
Prof. Alan Heavens (rapporteur),
Prof. Ofer Lahav (examinateur),
Prof. Will Percival (examinateur),
Prof. Rien van de Weijgaert (invité),
and Prof. Matías Zaldarriaga (invité).

Preface

p.vi and viii: Various typos corrected.

Chapter 1

p.25: References to Melott, 1994 and Sahni & Coles, 1995 added.
p.26, before equation (1.145): Reference for the frozen flow approximation (Matarrese et al., 1992) added.
p.26, before equation (1.149): References for the linearly-evolving potential approximation (Brainerd, Scherrer & Villumsen, 1993, Bagla & Padmanabhan, 1994) added.

Chapter 3

p.50, section 3.1.1: "this probability (definition)" now reads "this definition of probability".

Chapter 4

p.70, figure 4.3, right panel: Colorbar labels fixed.

Chapter 6

p.96: Reference for the renormalization group flow (Matarrese & Pietroni, 2007) corrected.

Chapter 9

p.131 The quote by Claude Shannon now appears after the table of contents, as it should.

Appendix B

p.166: Missing factor of H(0)2 added in the right-hand side of equation (B.6) and in the kick prefactor. I thank Ewoud Wempe for spotting this mistake.
p.170, 172, 173 and 174: Various typos corrected.
p.176, figure B.3: Labels corrected.
p.178, equation (B74): Fixed units so that initial LPT momenta are in physical units.
