We report on a wide-area (48' × 9') imaging survey of faint galaxies in the R and I bands toward the 1338+27 field where an unusual concentration of five QSOs at z ~ 1.1, embedded in a larger scale clustering of 23 QSOs, is known to exist. Using a quite homogeneous galaxy catalog with a detection completeness limit of I ~ 23.5, we detect a significant clustering signature of faint red galaxies with I > 21 and R-I > 1.2 over a scale extending to ~20 h Mpc. Close examination of the color… 
Superclustering of Galaxies Traced by a Group of QSOS at Z = 1.1
We present the result of a wide-area (48′ x 9′) imaging survey of faint galaxies toward the 1338+27 field where an unusual concentration of five QSOs at z ~ 1.1 is known to exist. We have detected a
Discovery of a large‐scale clumpy structure around the Lynx supercluster at z∼ 1.27
We report the discovery of a probable large-scale structure composed of many galaxy clumps around the known twin clusters at z = 1.26 and 1.27 in the Lynx region. Our analysis is based on deep,
The Galaxy Environment of a Quasar at z=1.226: A Possible Cluster Merger
We have conducted ultra-deep optical and deep near-infrared observations of a field around the z = 1.226 radio-quiet quasar 104420.8+055739 from the ClowesCampusano LQG of 18 quasars at z ∼ 1.3 in
Large-Scale Structure at z = 1.2 Outlined by Mg II Absorbers*
The largest known structure in the high-redshift universe is mapped by at least 18 quasars and spans ~5° × 25 on the sky, with a quasar spatial overdensity of 6-10 times above the mean. This large
Detection of 20-30 h^-^1 Mpc-scale galaxy structures embedded in 100 h^-^1 Mpc-scale structures of quasars and MgII absorbers at z 0.8 and z 1.2
We report the finding of two large-scale structures of galaxies in a 40 x 35 arcmin 2 field embedded in a 25 deg 2 area where two 100 h -1 Mpc-scale structures of quasars and Mgll absorbers at z ≃
Searching High-Redshift Large-Scale Structures: Photometry of Four Fields around Quasar Pairs at z ~ 1
We have studied the photometric properties of four fields around the high-redshift quasar pairs QP 1310+0007, QP 1355-0032, QP 0110-0219, and QP 0114-3140 at z ~ 1 with the aim of identifying
An H-alpha search for over-dense regions at z=2.23
We present the results of a narrow-band (H2S1, 2.121/0.021um) imaging search with WFCAM/UKIRT for H-alpha emitters around several potential signposts of rare (10^-7-10^-8 Mpc^-3) over-dense regions
Optical Identification of the ASCA Lynx Deep Survey: An Association of Quasi-Stellar Objects and a Supercluster at z=1.3?
Results of optical identification of the ASCA Lynx Deep Survey are presented. Six X-ray sources are detected in the 2-7 keV band using the Solid-State Imaging Spectrometer in a ~20' × 20' field of
The [O II] λ3727 luminosity function and star formation rate at z~1.2 in the COSMOS 2 square degree field and the Subaru deep field
We have carried out a wide-field imaging survey for [O II] λ3727 emitting galaxies at z ≈ 1.2 in the HST COSMOS 2 square degree field using the Suprime-Cam on the Subaru Telescope. The survey covers
Two close large quasar groups of size ∼ 350 Mpc at
The Clowes & Campusano large quasar group (LQG) at  has been re-examined using the quasar data from the DR7QSO catalogue of the Sloan Digital Sky Survey. In the 1991 discovery, the LQG impinged on

Galaxy clusters with QSOs at redshift 1.1
We report imaging of z∼1.1 QSO fields with R, I, and 75 A narrow-band filters tuned to the redshift wavelength of [O II] 3727 A. The data presently in hand cover four radio-quiet QSOs and one radio
Companions of Qsos at Redshift 1.1
We discuss broad- and narrow-band imaging of 7 arcmin fields of 14 QSOs with redshift ~1.1. The narrow-band filters were chosen to detect redshifted [O II] 3727A, and the broad bands are R and I,
Color-Magnitude Sequence in the Clusters at z ~ 1.2 near the Radio Galaxy 3C 324
We have investigated the optical and near-infrared colors of K'-selected galaxies in clusters at z ~ 1.2 near to the radio galaxy 3C 324 using images obtained with the Subaru telescope and archival

We present constraints on the evolution of large-scale structure from a catalog of 710,000 galaxies with IAB ? 24 derived from a KPNO 4 m CCD imaging survey of a contiguous 4? ? 4? region. The
