Description
The Epoch of Reionization (EoR) remains one of the last frontiers of observational cosmology. The Square Kilometer Array (SKA) is poised to make a preliminary detection of the 21-cm EoR signal within the next decade, and the race will ignite for a confirmation of this detection. One of the most promising avenues is through cross-correlation with galaxies in the same field. I present a framework for self-consistently simulating 21-cm and galaxy fields and then computing their cross-power spectrum, including a forecast of the achievable signal-to-noise ratio of a cross-correlation measurement made using the SKA and the European Large Telescope (ELT) MOSAIC instrument. We demonstrate that a MOSAIC Lyman alpha emitter survey overlapping with one square degree of the SKA field at a depth of 27.3 AB-magnitudes can achieve S/N~8 in under 100 hours of observation.
