Discovery of a high-redshift Einstein ring
R. A. Cabanac, D. Valls-Gabaud, A. O. Jaunsen +2
We report the discovery of a partial Einstein ring of radius 1.48arcsec produced by a massive (and seemingly isolated) elliptical galaxy. The spectroscopic follow-up at the VLT rev…
Cosmological Interpretation from High Redshift Clusters Observed Within the XMM-Newton -Project
Alain Blanchard
During the last ten years astrophysical cosmology has brought three remarkable results of deep impact for fundamental physics: the existence of non-baryonic dark matter, the (nearl…
Ionising stellar populations in circumnuclear star forming regions
Enrique Perez-Montero, Angeles I. Diaz, Marcelo Castellanos
We present a study of the stellar populations and gas physical conditions in Circumnuclear Star Forming Regions (CNSFRs) based on spectrophotometric data, including the 7000 angstr…
XMM-Newton study of the lensing cluster of galaxies CL0024+17
Y. -Y. Zhang, H. Boehringer, Y. Mellier +2
We present a detailed gravitational mass measurement based on the XMM-Newton imaging spectroscopy analysis of the lensing cluster of galaxies CL0024+17 at z=0.395. The emission app…
An ISOCAM survey through gravitationally lensing galaxy clusters. II. The properties of infrared galaxies in the A2218 field
A. Biviano, L. Metcalfe, B. McBreen +10
We observed the cluster Abell 2218 (z=0.175), with ISOCAM on board the Infrared Space Observatory, using two filters with reference wavelengths of 6.7 and 14.3 microns. We detected…
Detecting compact dark matter in galaxy clusters via gravitational microlensing: A2218 & A370
Artem Tuntsov, Geraint Lewis, Rodrigo Ibata +1
After decades of searching, the true nature of dark matter still eludes us. One potential probe of the form of dark matter in galaxy clusters is to search for microlensing variabil…
