Based on Cosmic Microwave Background (CMB) maps from the 2013 Planck Mission data release, this paper presents the detection of the Integrated Sachs-Wolfe (ISW) effect, i.e., the correlation between the CMB and large-scale evolving gravitational potentials. The significance of detection ranges from 2 to 4 σ, depending on which method is used. We investigate(More)
We study the impact of 1/f noise on the Planck Low Frequency Instrument (LFI) observations (Mandolesi et al. 1998) and describe a simple method for removing striping effects from the maps for a number of different scanning strategies. A configuration with an angle between telescope optical axis and spin-axis just less than 90 • (namely 85 •) shows good(More)
We report the results of a joint analysis of data from BICEP2/Keck Array and Planck. BICEP2 and Keck Array have observed the same approximately 400  deg^{2} patch of sky centered on RA 0 h, Dec. -57.5°. The combined maps reach a depth of 57 nK deg in Stokes Q and U in a band centered at 150 GHz. Planck has observed the full sky in polarization at seven(More)
Measurements of the cosmic microwave background (CMB) allow high precision observation of the cosmic plasma at redshift z ∼1100. After the success of the NASA satellite COBE, that in 1992 provided the first detection of the CMB anisotropy, results from many ground-based and balloon-borne experiments have showed a remarkable consistency between different(More)
1 ABSTRACT — We present an analysis of simultaneous multifrequency measurements of the Galactic emission in the 1-10 GHz range with 18 • angular resolution taken from a high altitude site. Our data yield a determination of the synchrotron spectral index between 1.4 GHz and 7.5 GHz of α syn = 2.81 ± 0.16. Combining our data with the maps from Haslam et al.(More)
The activation of lymphocytes by gefitinib treatment has been described. In this phase II pilot trial, we explored the possible synergism between IL-2 and gefitinib for non-small cell lung cancer (NSCLC) treatment. From September, 2003, to November, 2006, 70 consecutive patients with advanced, progressive NSCLC, previously treated with chemotherapy,(More)
Signal digitisation may produce significant effects in balloon-borne or space CMB experiments, when the limited bandwidth for downlink of data requires for loss-less data compression. In fact, the data compressibilty depends on the quantisation step q applied on board by the instrument acquisition chain. In this paper we present a study of the impact of the(More)
A detailed knowledge of the Galactic radio continuum is of high interest for studies of the dynamics and structure of the Galaxy as well as for the problem of foreground removal in Cosmic Microwave Background measurements. In this work we present a full-sky study of the diffuse Galactic emission at frequencies of few GHz, where synchrotron radiation is by(More)
We report on the design, fabrication and testing of a set of high performance corrugated feed horns at 30 GHz, 70 GHz and 100 GHz, built as advanced prototypes for the Low Frequency Instrument (LFI) of the ESA Planck mission. The electromagnetic designs include linear (100 GHz) and dual shaped (30 and 70 GHz) profiles. Fabrication has been achieved by(More)
Accurate measurements of the Cosmic Microwave Background (CMB) anisotropy call for high precision and reliability of the in-flight calibration. For extended surveys the CMB dipole provides an excellent calibration source at frequencies lower than ∼ 200 GHz; however poorly known foreground emissions, such as diffuse galactic components, complicate the signal(More)
