In this paper we present fluxes of galactic cosmic ray nuclei with energies above 40 MeV/n observed by the Kiel Electron Telescope on board the Ulysses spacecraft during the fast scan from the South Pole (September 1994) to the North Pole (July 1995). This part of the Ulysses orbit gives us the unique opportunity to investigate spatial modulation of cosmic(More)
Recent XMM-Newton observations reveal an extended (r ≈ 150′′) low-surface brightness X-ray halo in the supernova remnant G21.5-0.9. The near circular symmetry, the lack of any limb brightening and the nonthermal spectral form, all favour an interpretation of this outer halo as an extension of the central synchrotron nebula rather than as a shell formed by(More)
Simbol–X is a hard X–ray mission, operating in the ∼ 0.5–80 keV range, proposed as a collaboration between the French and Italian space agencies with participation of German laboratories for a launch in 2013. Relying on two spacecrafts in a formation flying configuration, Simbol–X uses for the first time a 20 m focal length X–ray mirror to focus X–rays with(More)
Aims. The neutron star low-mass X-ray binary GRS 1741.9–2853 is a known type-I burster of the Galactic Center. It is transient, faint, and located in a very crowded region, only 10′ from the supermassive black hole Sgr A. Therefore, its bursting behavior has been poorly studied so far. In particular, its persistent emission has rarely been detected between(More)
The Transport Collaboration, consisting of researchers from institutions in France, Germany, Italy and the USA, has established a program to make new measurements of nuclear interaction cross sections for heavy projectiles (Z > or = 2) in targets of liquid H2, He and heavier materials. Such cross sections directly affect calculations of galactic and solar(More)
SIMBOL-X is a hard X-ray mission, operating in the ~ 0.5–70 keV range, which is proposed by a consortium of European laboratories in response to the 2004 call for ideas of CNES for a scientific mission to be flown on a formation flying demonstrator. Relying on two spacecrafts in a formation flying configuration, SIMBOL–X uses for the first time a ~ 30 m(More)
The XMM-Newton X-ray observatory performed a pointed observation of the bursting pulsar GRO J1744-28 in April 2001 for about 10 ks during a program devoted to the scan of the Galactic center region. After the discovery of this source by BATSE in December 1995 during a very active bursting phase, it has been in quiescence since April 1997. We present here(More)
We report the development of a Si-based micro thermogenerator build from silicon-oninsulator by using standard CMOS processing. Ultrathin layers of Si, 100 nm in thickness, with embedded n and p-type doped regions electrically connected in series and thermally in parallel, are the active elements of the thermoelectric device that generate the thermopower(More)
