Laue and Fresnel lenses

Autor: Virgilli, Enrico, Halloin, Hubert, Skinner, Gerald

The low-energy gamma-ray domain is an important window for the study of the high energy Universe. Here matter can be observed in extreme physical conditions and during powerful explosive events. However, observing gamma-rays from faint sources is ext

Following the selection of The Gravitational Universe by ESA, and the successful flight of LISA Pathfinder, the LISA Consortium now proposes a 4 year mission in response to ESA's call for missions for L3. The observatory will be based on three arms w

Long term characterization of voltage references

Autor: Halloin, Hubert, Prat, Pierre, Brossard, Julien

We report here the characterization (temperature coefficients and noise level) of selected voltage references in the frequency range from 10^(-5) to 10 Hz. The goal of this work is to update previous studies, with a characterization at lower frequenc

Imaging the Gamma-Ray Sky with SPI aboard INTEGRAL

Autor: Knödlseder, Jürgen, Weidenspointner, Georg, Jean, Pierre, Diehl, Roland, Strong, Andrew, Halloin, Hubert, Cordier, Bertrand, Schanne, Stéphane, Winkler, Chris

The spectrometer SPI on INTEGRAL allows for the first time simultaneous imaging of diffuse and point-like emission in the hard X-ray and soft gamma-ray regime. To fully exploit the capabilities of the instrument, we implemented the MREM image deconvo

Radioactive 26Al and massive stars in the Galaxy

Gamma-rays from radioactive 26Al (half life ~7.2 10^5 yr) provide a 'snapshot' view of ongoing nucleosynthesis in the Galaxy. The Galaxy is relatively transparent to such gamma-rays, and emission has been found concentrated along the plane of the Gal
