Euclid. I. Overview of the Euclid mission / Euclid Collaboration
The current standard model of cosmology successfully describes a variety of measurements, but the nature of its main ingredients, dark matter and dark energy, remains unknown. Euclid is a medium-class mission in the Cosmic Vision 2015-2025 programme of the European Space Agency (ESA) that will provide high-resolution optical imaging, as well as near-infrared imaging and spectroscopy, over about 14,000 deg^2 of extragalactic sky. [...]

Intra Cluster Light properties in the CLASH-VLT cluster MACS J1206.2-0847 / Presotto, V (Trieste U. ; Trieste Observ.) ; Girardi, M (Trieste U. ; Trieste Observ.) ; Nonino, M (Trieste Observ.) ; Mercurio, A (Capodimonte Observ.) ; Grillo, C (DARK Cosmology Ctr.) ; Rosati, P (Ferrara U.) ; Biviano, A (Trieste Observ.) ; Annunziatella, M (Trieste U. ; Trieste Observ.) ; Balestra, I (Trieste Observ. ; Capodimonte Observ.) ; Cui, W (Trieste U. ; Trieste Observ. ; Western Australia U.) et al.
We aim at constraining the assembly history of clusters by studying the intra cluster light (ICL) properties, estimating its contribution to the fraction of baryons in stars, f*, and understanding possible systematics/bias using different ICL detection techniques. We developed an automated method, GALtoICL, based on the software GALAPAGOS to obtain a refined version of typical BCG+ICL maps. [...]

CLASH-VLT: The mass, velocity-anisotropy, and pseudo-phase-space density profiles of the z=0.44 galaxy cluster MACS 1206.2-0847 / Biviano, A. ; Rosati, P. ; Balestra, I. ; Mercurio, A. ; Girardi, M. ; Nonino, M. ; Grillo, C. ; Scodeggio, M. ; Lemze, D. ; Kelson, D. et al.
We use an unprecedented data-set of about 600 redshifts for cluster members, obtained as part of a VLT/VIMOS large programme, to constrain the mass profile of the z=0.44 cluster MACS J1206.2-0847 over the radial range 0-5 Mpc (0-2.5 virial radii) using the MAMPOSSt and Caustic methods. We then add external constraints from the gravitational lensing analysis of Umetsu et al [...]

ORIGIN: Metal Creation and Evolution from the Cosmic Dawn / Herder, Jan-Willem den (SRON, Utrecht) ; Piro, Luigi (IASF, Bologna) ; Ohashi, Takaya (Tokyo Metropolitan U.) ; Kouveliotou, Chryssa (NASA, Marshall) ; Hartmann, Dieter H. (Stanford U., Phys. Dept.) ; Kaastra, Jelle S. (SRON, Utrecht) ; Amati, L. (IASF, Bologna) ; Andersen, M.I. (DARK Cosmology Ctr.) ; Arnaud, M. (Saclay) ; Attéia, J.-L. (Midi-Pyrenees Observ.) et al.
ORIGIN is a proposal for the M3 mission call of ESA aimed at the study of metal creation from the epoch of cosmic dawn. Using high-spectral resolution in the soft X-ray band, ORIGIN will be able to identify the physical conditions of all abundant elements between C and Ni to red-shifts of z=10, and beyond. [...]
