SARCS strong-lensing galaxy groups: II - mass-concentration relation and strong-lensing bias
G. Foëx, V. Motta, E. Jullo +2
Our work is based on the stacked weak-lensing analysis of a sample of 80 strong-lensing galaxy groups. Our main results are the following: (i) the lensing signal does not allow us…
Characterizing SL2S galaxy groups using the Einstein radius
T. Verdugo, V. Motta, G. Foëx +11
We analyzed the Einstein radius, , in our sample of SL2S galaxy groups, and compared it with (the distance from the arcs to the center of the lens), using three differen…
The abundance of Bullet-groups in LCDM
J. G. Fernandez-Trincado, J. E. Forero-Romero, G. Foex +2
We estimate the expected distribution of displacements between the two dominant dark matter (DM) peaks (DM-DM displacements) and between DM and gaseous baryon peak (DM-gas displace…
Dark matter-baryons separation at the lowest mass scale: the Bullet Group
F. Gastaldello, M. Limousin, G. Foëx +13
We report on the X-ray observation of a strong lensing selected group, SL2S J08544-0121, with a total mass of which revealed a separatio…
