Rapid continuum variability in NGC 4151

DOI: 10.1016/S0273-1177(97)00616-9 Bibcode: 1998AdSpR..21...77E

Crenshaw, D. M.; Malkan, M.; Warwick, R. +4 more

Intensive monitoring of NGC 4151 showed strong, correlated variability at X-ray, ultraviolet, and optical wavelengths. The strongest variations were seen in ~1.5 keV X-rays, with weaker variations at ~100 keV and no significant variability in the 0.1-1 keV bands. In the ultraviolet/optical regime, the fractional variability amplitude decreased fro…

Specialized detector techniques and electronics of the ERNE instrument onboard SOHO

DOI: 10.1016/S0920-5632(97)00532-X Bibcode: 1998NuPhS..61....6V

Valtonen, E.; Peltonen, J.; Eronen, T. +5 more

ERNE is designed to study the composition and energy spectra of particles encountered in interplanetary space in the energy range from 1 MeV/n to well beyond 500 MeV/n. Several innovative ideas had to be incorporated in the design of the instrument in order to fulfill the scientific requirements. Position-sensitive strip detectors are used in the …

Doppler receiver for Cassini radio science experiments

DOI: 10.1016/S0032-0633(97)00137-2 Bibcode: 1998P&SS...46.1415C

Comoretto, G.

The Ka band tracking capability of the Cassini spacecraft allows for greater accuracy in most Radio Science experiments, but can be used only with the Goldstone DSN complex, i.e. for one third of the total time. A digital receiver has been designed to allow receiving the Ka band signal from a generic VLBI antenna. The receiver interfaces with the …

ISO Observations of Freshly Synthesized Supernova Material

DOI: 10.1023/A:1001198615504 Bibcode: 1998Ap&SS.255..221L

Lagage, P. -O.

ISOCAM observations of Cassiopeia A (Cas A), the youngest supernova remnant known in our galaxy, are discussed. We show how these observations are of interest for the so-called Cas A Neon problem and how these observations have renewed the interest in supernovae as dust factories.
