An on-going multi-wavelength survey of Ly-alpha emitters at redshifts z   = 2 - 8
  In the last decade, the technique of finding Ly-alpha emitters through narrow-band imaging has become a promising method of detecting high redshift galaxies. Ly-alpha emitters have been found from redshifts z ~ 2, up to the highest redshift source known to date at z = 6.96. Several surveys are also underway to find z = 7 - 9 sources. But these very high redshift sources are too faint to be studied in great detail, and more information can be found from studying the same class of objects at lower redshifts. Here we present our survey strategy to determine the nature of Ly-alpha emitters at lower redshifts, through multi-wavelength surveys, and our plans to extend the survey to redshift z = 8.8.
