Probing population III stars in galaxy IOK-1 at z = 6.96 through He II emission
The He II λ1640 emission line has been suggested as a direct probe of Population III (PopIII) stars at high redshift, since it can arise from highly energetic ionizing photons associated with hot, metal-free stars. We use the Hubble Space Telescope WFC3/
