The Gamma-Flash data acquisition system for observation of terrestrial gamma-ray flashes
Andrea Bulgarelli, Antonio Addis, Alessio Aboudan +20
Gamma-Flash is an Italian project funded by the Italian Space Agency (ASI) and led by the National Institute for Astrophysics (INAF), devoted to the observation and study of high-e…
Upgrading the high contrast imaging facility SPHERE: science drivers and instrument choices
A. Boccaletti, G. Chauvin, F. Wildi +71
SPHERE+ is a proposed upgrade of the SPHERE instrument at the VLT, which is intended to boost the current performances of detection and characterization for exoplanets and disks. S…
In-flight measurement of Planck telescope emissivity
F. Cuttaia, L. Terenzi, G. Morgante +19
The Planck satellite in orbit mission ended in October 2013. Between the end of Low Frequency Instrument (LFI) routine mission operations and the satellite decommissioning, a dedic…
The On-Site Analysis of the Cherenkov Telescope Array
Andrea Bulgarelli, Valentina Fioretti, Andrea Zoli +54
The Cherenkov Telescope Array (CTA) observatory will be one of the largest ground-based very high-energy gamma-ray observatories. The On-Site Analysis will be the first CTA scienti…
Parallel waveform extraction algorithms for the Cherenkov Telescope Array Real-Time Analysis
Andrea Zoli, Andrea Bulgarelli, Adriano De Rosa +4
The Cherenkov Telescope Array (CTA) is the next generation observatory for the study of very high-energy gamma rays from about 20 GeV up to 300 TeV. Thanks to the large effective a…
A comparison of CMB Angular Power Spectrum Estimators at Large Scales: the TT case
Diego Molinari, Alessandro Gruppuso, Gianluca Polenta +5
In the context of cosmic microwave background (CMB) data analysis, we compare the efficiency at large scale of two angular power spectrum algorithms, implementing, respectively, th…
Cosmological Parameters from a re-analysis of the WMAP-7 low resolution maps
F. Finelli, A. De Rosa, A. Gruppuso +1
Cosmological parameters from WMAP 7 year data are re-analyzed by substituting a pixel-based likelihood estimator to the one delivered publicly by the WMAP team. Our pixel based est…
Planck Early Results. II. The thermal performance of Planck
Planck Collaboration, P. A. R. Ade, N. Aghanim +225
The performance of the Planck instruments in space is enabled by their low operating temperatures, 20K for LFI and 0.1K for HFI, achieved through a combination of passive radiative…
Planck Early Results: The Planck mission
Planck Collaboration, P. A. R. Ade, N. Aghanim +272
The European Space Agency's Planck satellite was launched on 14 May 2009, and has been surveying the sky stably and continuously since 13 August 2009. Its performance is well in li…
New constraints on Parity Symmetry from a re-analysis of the WMAP-7 low resolution power spectra
A. Gruppuso, F. Finelli, P. Natoli +4
The Parity symmetry of the Cosmic Microwave Background (CMB) pattern as seen by WMAP 7 is tested jointly in temperature and polarization at large angular scale. A Quadratic Maximum…
Power Asymmetries in the Cosmic Microwave Background Temperature and Polarization patterns
F. Paci, A. Gruppuso, F. Finelli +4
We test the asymmetry of the Cosmic Microwave Background anisotropy jointly in temperature and polarization. We study the hemispherical asymmetry, previously found only in the temp…
Planck-LFI: Design and Performance of the 4 Kelvin Reference Load Unit
Luca Valenziano, Francesco Cuttaia, Adriano De Rosa +35
The LFI radiometers use a pseudo-correlation design where the signal from the sky is continuously compared with a stable reference signal, provided by a cryogenic reference load sy…
Cryogenic environment and performance for testing the Planck radiometers
L. Terenzi, M. Lapolla, M. Laaninen +21
This paper is part of the Prelaunch status LFI papers published on JINST: http://www.iop.org/EJ/journal/-page=extra.proc5/jinst The Planck LFI Radiometer Chain Assemblies (RCAs) ha…
New estimates of the CMB angular power spectra from the WMAP 5 yrs low resolution data
A. Gruppuso, A. De Rosa, P. Cabella +5
A Quadratic Maximum Likelihood (QML) estimator is applied to the WMAP 5 year low resolution maps to compute the CMB angular power spectra at large scales for both temperature and p…
