Speaker
Matteo Viel
(L'Osservatorio Astronomico di Trieste)
Description
Matteo will review the current constraints that intergalactic medium (IGM) data can place on:
1) the coldness of cold dark matter and its small scale properties;
2) neutrino masses;
3) cosmological parameters in standard and non-standard scenarios and implications for dark matter.
He will compare observational results (from high resolution and low-resolution quasar spectra) to state-of-the-art hydrodynamic simulations of the high redshift universe.
