Gaia Data Release 1 Summary of the astrometric, photometric, and survey properties

Stephan Morgenthaler, Mikaël Martino, Shuangqing Liao

Context. At about 1000 days after the launch of Gaia we present the first Gaia data release, Gaia DR1, consisting of astrometry and photometry for over 1 billion sources brighter than magnitude 20.7. Aims. A summary of Gaia DR1 is presented along with illu ...

Zodiacal emission

Xin Chen, Julien Lesgourgues, Fabio Finelli

The Planck satellite provides a set of all-sky maps at nine frequencies from 30 GHz to 857 GHz. Planets, minor bodies, and di ff use interplanetary dust emission (IPD) are all observed. The IPD can be separated from Galactic and other emissions because Pla ...

Background studies for acoustic neutrino detection at the South Pole

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

The detection of acoustic signals from ultra-high energy neutrino interactions is a promising method to measure the flux of cosmogenic neutrinos expected on Earth. The energy threshold for this process depends strongly on the absolute noise level in the ta ...

IceCube sensitivity for low-energy neutrinos from nearby supernovae

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

This paper describes the response of the IceCube neutrino telescope located at the geographic south pole to outbursts of MeV neutrinos from the core collapse of nearby massive stars. IceCube was completed in December 2010 forming a lattice of 5160 photomul ...

Search for relativistic magnetic monopoles with the AMANDA-II neutrino telescope

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

We present the search for Cherenkov signatures from relativistic magnetic monopoles in data taken with the AMANDA-II detector, a neutrino telescope deployed in the Antarctic ice cap at the Geographic South Pole. The non-observation of a monopole signal in ...

Determination of the atmospheric neutrino flux and searches for new physics with AMANDA-II

Shirit Cohen, Mathieu Ribordy, Levent Demirörs, Xiaoxia Bai

The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV energy range. The zenith angle and energy distribution of these events can be u ...

Alignment and signed-intensity anomalies in WMAP data

Pierre Vandergheynst, Yves Wiaux

Significant alignment and signed-intensity anomalies of local features of the cosmic microwave background (CMB) are detected on the three-year WMAP data, through a decomposition of the signal with steerable wavelets on the sphere. In addition to identifyin ...
