J09: Probing the Hydrogen Universe (1)

Wednesday, August 20  13:40-15:40,  Room #12

Radio observations of neutral hydrogen provide a unique probe of the universe over most of cosmic time, yielding results that drive modern cosmology, astrophysics and fundamental physics. Key science objectives include the detection and characterization of the Epoch of Reionization (EoR), detection and characterization of Baryonic Acoustic Oscillations (BAOs), and the history of Galaxy Evolution from the time of the first galaxies to the present day. These science topics will be addressed by the SKA, and a number of pathfinder experiments and facilities have been established to obtain early science results.
