Evaluation of the Primary Energy of UHE Photon-induced Atmospheric Showers from Ground Array Measurements
Pierre Billoir, Cecile Roucelle, Jean-Christophe Hamilton
A photon induced shower at eV exhibits very specific features and is different from a hadronic one. At such energies, the LPM effect delays in average the fir…
Coverage and large scale anisotropies estimation methods for the Pierre Auger Observatory
The Pierre Auger Collaboration
When searching for anisotropies in the arrival directions of Ultra High Energy Cosmic Rays, one must estimate the number of events expected in each direction of the sky in the case…
Archeops results
J. -Ch. Hamilton, A. Benoît, the Archeops Collaboration
\Archeops is a balloon--borne instrument dedicated to measuring cosmic microwave background (CMB) temperature anisotropies at high angular resolution ( 12 arcmin.) over a lar…
Noise power spectrum estimation and fast map making for CMB experiments
Alexandre Amblard, Jean-Christophe Hamilton
We present a method designed to estimate the noise power spectrum in the time domain for CMB experiments. The noise power spectrum is extracted from the time ordered data avoiding…
Bulge Microlensing Optical Depth from EROS 2 observations
C. Afonso, J. -N. Albert, C. Alard +7
We present a measurement of the microlensing optical depth toward the Galactic bulge based on the analysis of 15 contiguous1 square degrees fields centered on (l=2.5 deg, b=-4.0 de…
Galactic Foregrounds in OVRO and UCSB South Pole 1994 Cosmic Microwave Background Anisotropy Data
Pia Mukherjee, Brian Dennison, Bharat Ratra +3
We study Galactic emission foreground contamination of the OVRO and UCSB South Pole 1994 cosmic microwave background (CMB) anisotropy data by cross-correlating with templates of in…
Archeops: A High Resolution, Large Sky Coverage Balloon Experiment for Mapping CMB Anisotropies
A. Benoit, P. Ade, A. Amblard +3
Archeops is a balloon-borne instrument dedicated to measuring cosmic microwave background (CMB) temperature anisotropies at high angular resolution (8 arcminutes) over a large frac…
Preliminary results and perspectives in the Archeops experiment
Jean-Christophe Hamilton
Observations of the Cosmic Microwave Background (CMB) temperature fluctuations are a powerful tool for testing theories of the early Universe and for measuring cosmological paramet…
