| dc.description.abstract | We present results from precision X-ray spectroscopy using high-resolution ([delta lambda] = 0.01A) spectra of 3C 273 jet knots extracted from eight observations made using Chandra in conjunction with the HETGS. Using these spectra we searched for narrow emission line candidates and, based on significance values calculated for the observed photon counts in each bin of the spectrum of the entire jet, we selected three possible emission candidates and attempted to match these with known highly emissive X-ray emission lines. From this calculation we found the temperature of the X-ray emitting plasma to be 106.8 K, the bulk velocity of the knots to be 0.78 times the speed of light, and the electron density in the jet to be 0.043+/-.007 .009cm-3. | en_US |
