Finding the brightest cosmic beacons in the Southern Hemisphere.

The study of absorptions along the lines of sight to bright high-$z$ QSOs is an invaluable cosmological tool that provides a wealth of information on the inter-/circum-galactic medium, Dark Matter, primordial elements, reionization, fundamental constants, and General Relativity. Unfortunately, the number of bright ($i \lesssim$ 18) QSOs at $z \gtrsim 2$ in the Southern hemisphere is much lower than in the North, due to the lack of wide multi-wavelength surveys at declination $\delta 2.5$, corresponding to a success rate of our method of $\sim$ 80\%. Furthermore, we estimate a completeness of $\sim$ 90\% of our sample at completion of our observation campaign. The new QSOs confirmed by this first and the forthcoming campaigns will be the targets of subsequent studies using higher resolution spectrographs, like ESPRESSO, UVES, and (in the long term) ELT/HIRES.
