Finding the Oldest Star 

The discovery of entire, apparently well-developed, galaxies at unexpectedly high red shifts by JWST has fuelled new interest in the very first stars that must have stood at the beginning of these galaxies. The first stars mark the transition from the cosmic dark ages to the modern universe that we know today, a universe that is filled with stars, galaxies, and...

Filaments: from the large-scale structure to the CGM

I will present a characterisation of filamentary structures at different scales, from the large-scale cosmic filaments forming the skeleton of the cosmic web, to the smaller-scale filaments playing a crucial role in the circum-galactic medium (CGM). Using the outputs of recent large-scale hydro-dynamical simulations, I will focus on some...
