A flat Universe from high-resolution maps of the cosmic microwave background radiation
TLDR
The first images of resolved structure in the microwave background anisotropies over a significant part of the sky are reported, consistent with that expected for cold dark matter models in a flat (euclidean) Universe, as favoured by standard inflationary models.
A measurement by BOOMERANG of multiple peaks in the angular power spectrum of the cosmic microwave background
This paper presents a measurement of the angular power spectrum of the cosmic microwave background from l = 75 to l = 1025 (~10' to 24) from a combined analysis of four 150 GHz channels in the…
Dancing in the dark: galactic properties trace spin swings along the cosmic web
A large-scale hydrodynamical cosmological simulation, Horizon-AGN , is used to investigate the alignment between the spin of galaxies and the large-scale cosmic filaments above redshift one. The…
Planck 2015 results. I. Overview of products and scientific results
The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14{\textasciitilde}May 2009and scanned the microwave and…
Connecting the cosmic web to the spin of dark haloes: implications for galaxy formation
We investigate the alignment of the spin of dark matter halos relative (i) to the surrounding large-scale filamentary structure, and (ii) to the tidal tensor eigenvectors using the Horizon 4π dark…
Extended Mosaic Observations with the Cosmic Background Imager
Two years of microwave background observations with the Cosmic Background Imager (CBI) have been combined to give a sensitive, high-resolution angular power spectrum over the range 400 2000 power…
The Anisotropy of the Microwave Background to l = 3500: Mosaic Observations with the Cosmic Background Imager
Using the Cosmic Background Imager (CBI), a 13-element interferometer array operating in the 26-36 GHz frequency band, we have observed 40 deg2 of sky in three pairs of fields, each ~145' × 165',…
Planck 2013 results. I. Overview of products and scientific results
The European Space Agency’s Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 and has been scanning the microwave and submillimetre sky…
Multiple Peaks in the Angular Power Spectrum of the Cosmic Microwave Background: Significance and Consequences for Cosmology
Multiple Peaks in the Angular Power Spectrum of the Cosmic Microwave Background: Significance and Consequences for Cosmology arXiv:astro-ph/0105296 v1 17 May 2001 P. de Bernardis 1 , P.A.R. Ade 2 ,…
Planck2013 results. XXIII. Isotropy and statistics of the CMB
We test the statistical isotropy and Gaussianity of the cosmic microwave background (CMB) anisotropies using observations made by the Planck satellite. Our results are based mainly on the full Planck…
