The Planck satellite has set a new frontier for cosmology, providing the most accurate measurements of cosmological parameters to date. It also left us with a number of new, interesting mysteries that might hint to the discovery of new physics. Current and upcoming CMB ground-based experiments will be able to explore these questions further, hopefully providing new insights into these...

Halo sparsity, the ratio of two masses of a dark matter halo measured at two different overdensities, has proven itself to be a promising avenue to probe cosmology using the internal structure of dark matter haloes. In this talk I will present multiple applications of halo sparsity beyond current cosmological constraints. Most notably I will show how sparsity correlates with the dynamical...

The 2-point Correlation Function and its Fourier-space counterpart, the Power Spectrum play a major role in the analysis of spectroscopic galaxy surveys. Yet, they do not describe the full statistical properties of cosmological perturbations at low redshift, a highly non-Gaussian random field. Non-Gaussian properties are quantified by higher-order correlation functions such as the galaxy...

The Deeper Wider Fast Programme (DWF) aims to discover and rapidly follow up the fastest bursts in the Universe (those lasting only milliseconds to hours). For this, we execute a main strategy comprised of coordinated international multi-facility, all-wavelength, and multi-messenger telescope observing runs to detect and follow up fast...

The study of flaring astrophysical events in the multi-messenger approach requires instantaneous follow-up observations to better understand the nature of these events through complementary observational data. We present Astro-COLIBRI as a meta platform for the patchwork of different specific tools in the real-time multi-messenger...
