The FSVS Cluster Catalogue: Galaxy Clusters and Groups in the Faint Sky Variability Survey
Ilona K. Soechting, Mark E. Huber, Roger G. Clowes +1
We describe a large sample of 598 galaxy clusters and rich groups discovered in the data of the Faint Sky Variability Survey. The clusters have been identified using a fully automa…
Discovery of Two New Faint Cataclysmic Variables
S. B. Howell, E. Mason, M. Huber +1
We report on the discovery of two new faint cataclysmic variables. The objects were selected as candidates from two different imaging surveys aimed at the discovery of such faint s…
Environments of Quasars in the Context of Large-Scale Structure
Ilona K. Söchting, R. G. Clowes, L. E. Campusano
We are looking at quasar environment in the context of large-scale structure (LSS) - a new approach, giving a more informed interpretation of quasar-galaxy correlations. This paper…
Large Scale Structure at z=1.2 Outlined by MgII Absorbers
G. M. Williger, L. E. Campusano, R. G. Clowes +1
The largest known structure in the high redshift universe is mapped by at least 18 quasars and spans ~5 deg x 2.5 deg on the sky, with a quasar spatial overdensity of 6-10 times ab…
The Galaxy Environment of Quasars in the Clowes-Campusano Large Quasar Group at z~1.3
C. P. Haines, R. G. Clowes, L. E. Campusano
The Clowes-Campusano Large Quasar Group (LQG) is the largest known structure at high redshifts, with at least 18 quasars at z~1.3 forming a structure ~200 Mpc across. We are conduc…
The Galaxy Environment of a Quasar at z=1.226: A Possible Cluster Merger
C. P. Haines, R. G. Clowes, L. E. Campusano +1
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 Clowes-Campusano LQG of 18 quasar…
The Galaxy Environment of Quasars in the z~1.3 Clowes-Campusano Large Quasar Group
C. P. Haines, R. G. Clowes, L. E. Campusano
We report significant associated clustering in the field of a z=1.226 quasar from the Clowes-Campusano LQG in the form of both a factor ~11 overdensity of I-K>3.75 galaxies and red…
A new assessment of the completeness of quasar surveys: implications for the luminosity function
Matthew J. Graham, Roger G. Clowes, Luis E. Campusano
We apply a simple statistical method (Derenzo & Hildebrand 1969) to estimating the completeness of quasar surveys. It requires that an area has been covered by two or more, prefera…
Large groups in the Chile-UK quasar survey
Peter R. Newman, Roger G. Clowes, Luis E. Campusano +1
The Chile-UK quasar survey, a new-generation 140 deg^2 UVX survey to B = 20, is now \sim 25 per cent complete. The catalogue currently contains 319 quasars and 93 emission line gal…
The ESO Key-Programme ``A Homogeneous Bright QSO Survey'' - I The Methods and the ``Deep'' Fields
S. Cristiani, F. La Franca, P. Andreani +13
This is the first paper in a series aimed at defining a statistically significant sample of QSOs in the range and . The selection is carried out u…
