The OSER project
Marc Moniez
The OSER project (Optical Scintillation by Extraterrestrial Refractors) is proposed to search for scintillation of extragalactic sources through the galactic -- disk or halo -- tra…
Properties of the energetic particle distributions during the October 28, 2003 solar flare from INTEGRAL/SPI observations

Analysis of spectra obtained with the gamma-ray spectrometer SPI onboard INTEGRAL of the GOES X17-class flare on October 28, 2003 is presented. In the energy range 600 keV - 8 MeV…
A statistical study of SUMER spectral images: events, turbulence, and intermittency
E. Buchlin, J. -C. Vial, P. Lemaire
We analyze a series of full-Sun observations, which was performed with the SoHO/SUMER instrument between March and October 1996. Some parameters (radiance, shift and width) of the…
Quantitative bispectra from multifield inflation
G. I. Rigopoulos, E. P. S. Shellard, B. J. W. van Tent
After simplifying and improving the non-Gaussian formalism we developed in previous work, we derive a quantitative expression for the three-point correlator (bispectrum) of the cur…
VIMOS-VLT and Spitzer observations of a radio galaxy at z=2.5

We present: 1) a kinematic and morphological study of the giant Lya nebula associated with the radio galaxy MRC2104-242 (z = 2.49) based on integral field spectroscopic VIMOS data…
Features of radio-detected Extensive Air Shower with CODALEMA
D. Ardouin, A. Belletoile, D. Charrier +9
Some performances of the present CODALEMA experiment, set up to analyse radio-detected Extensive Air Shower (EAS) events, are presented. Characteristics of the EAS electric field d…
ISM properties in low-metallicity environments I. mid-infrared spectra of dwarf galaxies
S. C. Madden, F. Galliano, A. P. Jones +1
We present new ISOCAM mid-infrared spectra of three starbursting nearby dwarf galaxies, NGC1569, IIZw40, NGC1140 and the 30Dor region of the LMC and explore the properties of the I…
Linking stellar mass and star formation in Spitzer/MIPS 24 micron galaxies
K. I. Caputi, H. Dole, G. Lagache +7
We present deep Ks<21.5 (Vega) identifications, redshifts and stellar masses for most of the sources composing the bulk of the 24 micron background in the GOODS/CDFS. Our identifie…
Constraining topology in harmonic space
M. Kunz, N. Aghanim, L. Cayon +3
We consider several ways to test for topology directly in harmonic space by comparing the measured a_lm with the expected correlation matrices. Two tests are of a frequentist natur…
Generating long streams of noise
S. Plaszczynski
We review existing methods for generating long streams of 1/f^alpha noise () focusing on the digital filtering of white noise. We detail the formalism to conceive an effi…
