  • Rapid Decline Of Ly Alpha Emission Toward The Reionization Era 

    Tilvi, Vithal; Papovich, Casey; Finkelstein, Steven L.; Long, J.; Song, Mimi; Dickinson, Mark; Ferguson, Henry C.; Koekemoer, A. M.; Giavalisco, Mauro; Mobasher, Bahram
    The observed deficit of strongly Ly alpha emitting galaxies at z > 6.5 is attributed to increasing neutral hydrogen in the intergalactic medium (IGM) and/or to the evolving galaxy properties. To investigate this we have ...
