In Paper 1 of this series we identified an 80 co-moving Mpc filament of candidate Lyman-alpha 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 5.0E-17 erg/cm^2/s/arcsec^2. Of the 14 candidates down to this limit, 12 were confirmed to be Lyman-alpha emitting galaxies at the filament redshift. We also obtained spectral confirmation for six of the lower surface brightness candidates, all of… 
Properties of Lyα and Gamma Ray Burst-Selected Starbursts at High Redshifts
Selection of starbursts through either deep narrow-band imaging of redshifted Lyα emitters, or localisation of host galaxies of gamma-ray bursts both give access to starburst galaxies that are
Evolution in the properties of Lyman-α emitters from redshifts z ~ 3 to z ~ 2
Context: Narrow-band surveys to detect Lyα emitters are powerful tools for identifying high, and very high, redshift galaxies. Although samples are increasing at redshifts z = 3 {-} 6, the nature of
Hot gas, cold gas and sub-haloes in a Lyman α blob at redshift 2.38
We present integral field spectroscopy of a Lyman α blob at redshift 2.38, with a spectral resolution three times better than previous published work. As with previous observations, the blob has a
Ultraviolet-Bright, High-Redshift Ultraluminous Infrared Galaxies
We present Spitzer Space Telescope observations of the z = 2.38 Lyα emitter overdensity associated with galaxy cluster J2143-4423, the largest known structure (110 Mpc) above z = 2. We imaged 22 of
He II Emission in Lyα Nebulae: Active Galactic Nucleus or Cooling Radiation?
We present a study of an extended Lyα nebula located in a known overdensity at z ~ 2.38. The data include multiwavelength photometry covering the rest-frame spectral range from 0.1 to 250 μm, and
A SINFONI integral field spectroscopy survey for galaxy counterparts to damped Lyman α systems – I. New detections and limits for intervening and associated absorbers*
Detailed studies of damped and sub-damped Lyman alpha systems (DLAs), the galaxies probed by the absorption they produce in the spectra of background quasars, rely on identifying the galaxy
A Damped Lyα Absorption-Line System in an Apparent Void at Redshift 2.38
Abstract We study the contents of an apparent void in the distribution of Lyα emitting galaxies at redshift 2.38. We show that this void is not empty, but contains a damped Lyα absorption-line
Possible Detection of Lyα Fluorescence from a Damped Lyα System at Redshift z ~ 2.8
We have detected Lyα emission from a damped Lyα system (DLA) that lies near the bright quasar HS1549+1919. The DLA has the same redshift as HS1549+1919 and was discovered in the spectrum of a faint
A Fabry-Pérot Imaging Search for Lyα Emission in Quasar Absorbers at z ~ 2.4
We have carried out a deep narrowband imaging survey of six fields with heavy-element quasar absorption lines, using the Goddard Fabry-Perot (FP) system at the Apache Point Observatory (APO) 3.5 m


A Group of Galaxies at Redshift 2.38
We report the discovery of a group of galaxies at redshift 2.38. We imaged about 10% of a claimed supercluster of QSO absorption-lines at z=2.38 (Francis & Hewett 1993). In this small field (2 arcmin
Detection of Lyman-α-emitting galaxies at redshift 4.55
STUDIESof the formation and early history of galaxies have been hampered by the difficulties inherent in detecting faint galaxy populations at high redshift. As a consequence, observations at the
Low-Metallicity Gas Clouds in a Galaxy Protocluster at Redshift 2.38
We present high-resolution spectroscopy of a QSO whose sight line passes through the halo of a pair of elliptical galaxies at redshift 2.38. This pair of galaxies probably lies at the center of a
Spectroscopic Confirmation of Three Redshift z~5.7 Lyα Emitters from the Large-Area Lyman Alpha Survey
Narrowband searches for Lyα emission are an efficient way of identifying star-forming galaxies at high redshifts. We present Keck Telescope spectra confirming redshifts z ≈ 5.7 for three objects
A Catalog of Rich Clusters of Galaxies
This is an all-sky catalog of 4073 rich clusters of galaxies, each having at least 30 members within the magnitude range m3 to m3 +2 (m3 is the magnitude of the third brightest cluster member) and
Detection of a redshift 3.04 filament
The lamentary structure of the early universe has until now only been seen in numerical simulations. Despite this lack of direct observational evidence, the prediction of early lamentary structure
Subaru Deep Survey. II. Luminosity Functions and Clustering Properties of Lyα Emitters at z = 4.86 in the Subaru Deep Field*
We report on early results from very deep and wide-field narrowband imaging on a 543 arcmin2 area of the Subaru Deep Field. We find 87 Lyα emitters (LAEs) at z = 4.86 ± 0.03 that are photometrically
The 2dF QSO Redshift Survey — I. The optical luminosity function of quasi-stellar objects
We present a determination of the optical luminosity function of quasi-stellar objects (QSOs) and its cosmological evolution with redshift for a sample of over 6000 QSOs identified primarily from the
Mapping the Universe
Maps of the galaxy distribution in the nearby universe reveal large coherent structures, including the "Great Wall", one of several serious challenges to current understanding of the origin and evolution of the large-scale distribution of matter in the universe.
A High Signal-to-Noise Ratio Composite Quasar Spectrum
A very high signal-to-noise ratio (S/N of about 400) composite spectrum of the rest-frame ultraviolet and optical region of high luminosity quasars is presented. The spectrum is derived from 718
