Abstract:
In Paper 1 (Palunas et al., 2004ApJ...602..545P 2004ApJ...602..545P) of this series we
identified an 80 comoving Mpc filament of candidate Lyα-emitting
galaxies at redshift 2.38. In this paper we present spectroscopy of
the 37 galaxy candidates. Our spectroscopy reached a surface
brightness limit of 5.0x10-17erg/cm2/s/arcsec2. Of the 14
candidates down to this limit, 12 were confirmed to be
Lyα-emitting galaxies at the filament redshift. We also obtained
spectral confirmation for six of the lower surface brightness
candidates, all of which also lay at the filament redshift. In
addition, we identify a foreground cluster of QSOs at z=1.65.
Description:
Our spectroscopy was carried out using the Two-Degree Field (2dF)
multifiber spectrograph on the Anglo-Australian Telescope (AAT).
Observations were carried out on the nights of 2003 August 31 and
September 1.
