Planck Intermediate Results. I. Further validation of new Planck clusters with XMM-Newton
The Planck Collaboration, N. Aghanim, M. Arnaud +182
We present further results from the ongoing XMM-Newton validation follow-up of Planck cluster candidates, detailing X-ray observations of eleven candidates detected at a signal-to-…
Gauge-invariant perturbations at second order in two-field inflation
Eleftheria Tzavara, Bartjan van Tent
We study the second-order gauge-invariant adiabatic and isocurvature perturbations in terms of the scalar fields present during inflation, along with the related fully non-linear s…
Hunting for Isocurvature Modes in the CMB non-Gaussianities
David Langlois, Bartjan van Tent
We investigate new shapes of local primordial non-Gaussianities in the CMB. Allowing for a primordial isocurvature mode along with the main adiabatic one, the angular bispectrum is…
COrE (Cosmic Origins Explorer) A White Paper
The COrE Collaboration, C. Armitage-Caplan, M. Avillez +72
COrE (Cosmic Origins Explorer) is a fourth-generation full-sky, microwave-band satellite recently proposed to ESA within Cosmic Vision 2015-2025. COrE will provide maps of the micr…
