Fossil Jets from Black Hole Transients

Observations of the fossil Xray jet from the black hole transient 4U 175533enabled us to detect the flux decay of the southern jet, identify the Xrayemission mechanism as synchrotron radiation, and place constraints on theenergetics of the jet. We propose for a third observation with the goals ofdetecting decay in the northern jet, more accurately measuring the southern jetdecay, and searching for motions within the jet. Detection of decay of thenorthern jet at a rate similar to the southern jet would imply that the kineticpower of the jet was comparable to the Xray luminosity while the source wasactive. We also propose observations of two additional sources likely to exhibitfossil Xray jets. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
