The molecular gas content of $z>$6.5 Lyman Alpha emitters
Little is known about the gas content of "normal" galaxies at redshifts,
$z>$6.5, around the time the Universe is believed to have been reionized.
Dust, along with atomic and molecular gas have been detected in extremely
luminous quasars at these early epochs, however, measuring the gas and
dust content of less-luminous galaxies, such as Lyman-alpha emitters, has
proven challenging. I will present GBT observations of CO line emission in
two $z>$6.5 lyman alpha emitters, with the goal of measuring their molecular
gas content. One of these, HCM6A at $z$=6.56, has been amplified by
gravitational lensing, so that we are able to place strong constraints on
its molecular gas content. I will also present observations of thermal
dust continuum emission and the 158$\mu$m C+ line emission in HCM6A using the
PdBI.
