Abstract :

Absorption lines seen in the spectra of high-z quasi-stellar objects (QSOs) allow one to probe the cosmology, galaxy formation and its evolution. In addition one will be able to place stringent constraints on the variations of fundamental constants. In this talk the author will review the present status of the field and summarize future programmes with Thirty-Metre Telescope (TMT).
