ASTRO-C, renamedGinga (Japanese for 'galaxy'), was anX-ray astronomysatellite launched from theKagoshima Space Center on 5 February 1987 usingM-3SII launch vehicle. The primary instrument for observations was the Large Area Counter (LAC). Ginga was the third JapaneseX-ray astronomy mission, followingHakucho andTenma (alsoHinotori satellite - which preceded Ginga - had X-ray sensors, but it can be seen as a heliophysics rather than X-ray astronomy mission). Ginga reentered the Earth's atmosphere on 1 November 1991.

Instruments

[edit]
  • Large Area Proportional Counter (LAC 1.5-37 keV)
  • All-Sky Monitor (ASM 1-20 keV)
  • Gamma-ray Burst Detector (GBD 1.5-500 keV)

Highlights

[edit]
  • Discovery of transient Black Hole Candidates and study of their spectral evolution.
  • Discovery of weak transients in the galactic ridge.
  • Detection of cyclotron features in 3X-ray pulsars: 4U1538-522, V0332+53, and Cep X-4.
  • Evidence for emission and absorption Fe feature inSeyfert probing reprocessing by cold matter.
  • Discovery of intense 6-7 keV iron line emission from theGalactic Center region.
