Observation of an anomalous positron abundance in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +48
Positrons are known to be produced in interactions between cosmic-ray nuclei and interstellar matter ("secondary production"). Positrons may, however, also be created by dark matte…
A new measurement of the antiproton-to-proton flux ratio up to 100 GeV in the cosmic radiation
O. Adriani, G. C. Barbarino, G. A. Bazilevskaya +50
A new measurement of the cosmic ray antiproton-to-proton flux ratio between 1 and 100 GeV is presented. The results were obtained with the PAMELA experiment, which was launched int…
Discovery of a very high energy gamma-ray signal from the 3C 66A/B region
MAGIC Collaboration, E. Aliu
The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 h in 2007 August-December. The observations resulted in the discovery of a gamma-ray source at ene…
Simulations of Galactic Cosmic Ray Impacts on the Herschel/PACS bolometer Arrays with Geant4 Code
C. Bongardo, P. M. Andreani, K. Okumura +5
The effects of the in-flight behaviour of the bolometer arrays of the Herschel/PACS instrument under impacts of Galactic cosmic rays are explored. This instrument is part of the ES…
Periodic very high energy gamma-ray emission from LS I +61 303 observed with the MAGIC telescope
MAGIC Collaboration, J. Albert
The MAGIC collaboration has recently reported the discovery of gamma-ray emission from the binary system LS I +61 303 in the TeV energy region. Here we present new observational re…
Making Maps from Planck LFI 30GHz Data with Asymmetric Beams and Cooler Noise
M. A. J. Ashdown, C. Baccigalupi, J. G. Bartlett +21
The Planck satellite will observe the full sky at nine frequencies from 30 to 857 GHz. The goal of this paper is to examine the effects of four realistic instrument systematics in…
