The enigma of the largest cosmic structures


The consensus ΛCDM (Lambda-Cold Dark Matter) model of cosmology has shown 
remarkable explanatory power over a variety of cosmic scales and epochs, and 
it narrates a reassuring story of a universe currently filled mostly with 
dark matter and dark energy. Yet, this explanation is not fully satisfactory 
because the actual nature of the dark components remains a puzzle. In this 
talk, I will review the most important new developments in cosmology and 
provide a summary of how the recently reported anomalies concerning the 
delicate balance of cosmic expansion and structure growth have further 
challenged the concordance model. In particular, I will focus on the analysis 
of the largest cosmic structures at 100 Megaparsec scales, and highlight my 
own contributions to state-of-the-art maps of the large-scale structure of 
the Universe, such as the Dark Energy Survey (DES), the ESA Euclid mission, 
and other upcoming sky-survey projects that may shed new light on the cosmic 
dark sector.
