SCI-HI: Searching for the First Galaxies

The experiment Sonda Cosmológica de la Islas para la Detección de Hidrógeno Neutro (SCI-HI) has set the first upper limit for  the detection of the formation of galaxies at the end of the Dark Ages (z~20).  For this aim we search for the spectral evolution of the 21 cm line of neutral Hydrogen. We present SCI-HI new developments and the possibility to develop the austral counterpart of SCI-HI in Argentina.
