Rossi X-ray Timing Explorer
From Wikipedia, the free encyclopedia
The Rossi X-ray Timing Explorer (RXTE) is a satellite that observes the time structure of astronomical x-ray sources. The RXTE has three instruments --the Proportional Counter Array, the High-Energy X-ray Timing Experiment(HEXTE), and one instrument called the All Sky Monitor. The RXTE observes x-rays from black holes, neutron stars, X-ray pulsars and x-ray bursts.
RXTE was launched from Cape Canaveral on 30 December 1995 on a Delta rocket, has an International Designator of 1995-074A and a mass of 3200 kg.
Observations from the Rossi X-ray Timing Explorer have been used as evidence for the existence of the frame-dragging effect predicted by the theory of general relativity. RXTE results have, as of late 2007, been used in more than 1400 scientific papers.
In January 2006 it was announced that Rossi had been used to locate a candidate intermediate-mass black hole named M82 X-1.[1]. In February 2006 data from RXTE was used to prove that the diffuse background x-ray glow in our galaxy comes from innumerable, previously undetected white dwarfs and from other stars' coronae. [1] In April 2008 RXTE data was used to infer the size of the smallest known black hole.[2]
