Abstract:
We describe the results of an extremely deep, 0.28°2 survey for
z=3.1 Lyα emission-line galaxies in the Extended Chandra Deep
Field-South. By using a narrowband 5000Å filter and complementary
broadband photometry from the MUSYC survey, we identify a
statistically complete sample of 162 galaxies with monochromatic
fluxes brighter than 1.5x10-17ergs/cm2/s and observer's frame
equivalent widths greater than 80Å
Description:
Narrowband observations of the ECDF-S were performed with the MOSAIC
II CCD camera on the CTIO Blanco 4m telescope. These data consisted of
a series of 111 exposures taken over 16 nights (between 2002 Oct 06
and 2004 Feb 20) through a 50Å wide full width at half-maximum
(FWHM) λ5000 filter.
