The XMM-LSS catalogue: X-ray sources and associated optical data. Version I
M. Pierre, L. Chiappetti, F. Pacaud +34
Following the presentation of the XMM-LSS X-ray source detection package by Pacaud et al., we provide the source lists for the first 5.5 surveyed square degrees. The catalogues per…
The XMM-LSS survey: the Class 1 cluster sample over the initial 5 square degrees and its cosmological modelling
F. Pacaud, M. Pierre, C. Adami +30
We present a sample of 29 galaxy clusters from the XMM-LSS survey over an area of some 5deg2 out to a redshift of z=1.05. The sample clusters, which represent about half of the X-r…
Photometric monitoring of the doubly imaged quasar UM673: possible evidence for chromatic microlensing
Th. Nakos, F. Courbin, J. Poels +12
We present the results of two-band CCD photometric monitoring of the gravitationally lensed quasar Q 0142-100 (UM 673).The data, obtained at ESO-La Silla with the 1.54 m Danish tel…
Reconstruction of the microlensing light curves of the Einstein Cross, QSO2237+0305: possible evidence of an accretion disk with a central hole
Dong-Wook Lee, J. Surdej, O. Moreau +2
Recent OGLE (Optical Gravitational Lensing Experiment) and GLITP (Gravitational Lens International Time Project) monitoring data for QSO 2237+0305 (Huchra et al.) have been analyze…
The XMM-LSS survey: optical assessment and properties of different X-ray selected cluster classes
C. Adami, A. Mazure, M. Pierre +29
XMM and Chandra opened a new area for the study of clusters of galaxies. Not only for cluster physics but also, for the detection of faint and distant clusters that were inaccessib…
QSO 2237+0305 VR light curves from Gravitational Lenses International Time Project optical monitoring
D. Alcalde, E. Mediavilla, O. Moreau +12
We present VR observations of QSO 2237+0305 conducted by the GLITP collaboration from 1999 October 1 to 2000 February 3. The observations were made with the 2.56 m Nordic Optical T…
