We present the detection of 34 Lyα emission-line galaxy candidates in a 80 × 80 × 60 comoving Mpc region surrounding the known z = 2.38 galaxy cluster J2143-4423. The space density of Lyα emitters is comparable to that found by Steidel et al. when targeting a cluster at redshift 3.09, which is a factor of 5.8 ± 2.5 greater than that found by field samples at similar redshifts. The distribution of these galaxy candidates contains several 5-10 Mpc scale voids. We compare our observations with… 
Discovery of six Lyα emitters near a radio galaxy at z ∼ 5.2
We present the results of narrow-band and broad-band imaging with the Very Large Telescope* of the field surrounding the radio galaxy TN J0924-2201 at z = 5.2. Fourteen candidate Lya emitters with a
Extended Lyα Emission from Interacting Galaxies at High Redshifts
Recent observations have discovered a population of extended Lyα sources, dubbed Lyα blobs (LABs), at high redshift z � 2 6.6. These LABs typically have a luminosity of L � 10 42 10 44 erg s −1 , and
Lyα-emitting galaxies at redshift z ∼ 4.5 in the lala cetus field
We present a large sample of Lyα-emitting galaxies (LAEs) spectroscopically confirmed at redshift z ≈ 4.5, based on Inamori-Magellan Areal Camera and Spectrograph spectroscopic observations of
Star formation in the XMMU J2235.3−2557 galaxy cluster at z= 1.39
We present the first results of a narrow-band photometric study of the massive galaxy cluster XMMU J2235.3-2557 at z = 1.39. We obtained deep H narrow-band imaging with the Near InfraRed Imager and
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
Extended and Filamentary Lyα Emission from the Formation of a Protogalactic Halo at z=2.63 ⋆ †
We report the observation of a further asymmetric, extended Lyα emitting halo at z = 2.63, from our ultra-deep, long-slit spectroscopic survey of faint high-redshift emitters, undertaken with
Protoclusters associated with distant radio galaxies
The results of a large program conducted with the Very Large Telescope and the Keck telescope to search for forming clusters of galaxies near powerful radio galaxies at 2 < z < 5.2 are presented.
Large-scale structure of Lyman break galaxies around a radio galaxy protocluster at z ~ 4
We present broad-band imaging with the Subaru Telescope of a 25 ' ×25 ' field surrounding the radio galaxy TN J1338- 1942 at redshift z = 4.1. The field contains excesses of Lyman-α emitters (LAEs)
A search for galaxies in and around an HI overdense region at z = 5
We present the discovery of a large-scale structure of emission-line galaxies at redshift z= 4.86 behind a massive cluster of galaxies, A1689. Previous spectroscopic observations of a galaxy,
The Overdense Environment of a Large Lyα Nebula at z ≈ 2.7
Large nebulae ( 50 kpc) emitting strongly in Ly? (also known as Ly? blobs) are likely signposts of ongoing massive galaxy formation. The relative rarity of these sources and their discovery in


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
A Large Structure of Galaxies at Redshift z ~ 3 and Its Cosmological Implications*
We report the discovery of a highly significant concentration of galaxies at a redshift of z = 3.090. The structure is evident in a redshift histogram of photometrically selected Lyman-break objects
An Infrared Search for Star-forming Galaxies at z > 2
We report the cumulative results of an ongoing near-infrared search for redshifted Hα emission from normal galaxies at z > 2. An infrared search reduces the bias due to reddening. Using narrowband
Compact Lyα-emitting candidates at z ≃ 2.4 in deep medium-band Hubble Space Telescope WFPC2 images
Medium-band imaging with Hubble Space Telescope (HST) Wide Field Planetary Camera 2 (WFPC2) in the F410M filter has previously revealed a population of compact Lyα emission objects around the radio
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
Spectroscopic Confirmation of a Population of Normal Star-Forming Galaxies at Redshifts z>3
We report the discovery of a substantial population of star--forming galaxies at $3.0 \simlt z \simlt 3.5$. These galaxies have been selected using color criteria sensitive to the presence of a Lyman

On the Gas Surrounding High-Redshift Galaxy Clusters *
Abstract Francis & Hewett (1993) identified two 10 Mpc-scale regions of the high-redshift universe that were seemingly very overdense in neutral hydrogen. Subsequent observations showed that at least
