A Compilation of Electronic Transitions in the CO Molecule and the Interpretation of Some Puzzling Interstellar Absorption Features

Morton, Donald C.; Noreau, Louis

This compilation lists wavenumbers, wavelengths, and oscillator strengths for 1589 electronic transitions of (12)C(16)O, (13)C(16)O, (12)C(18)O, and (13)C(18)O between 1000 and 1545 A. These are the transitions from J double prime = 0 to 6 and v double prime = 0 of the ground term which are most likely to appear as interstellar absorption lines in…

Hubble Space Telescope Observations of Synchrotron Jets

Sparks, W. B.; Macchetto, F.; Biretta, J. A.

The Hubble Space Telescope for the first time enables optical and UV images of jets to be obtained with spatial resolution comparable to radio interferometric techniques. Because synchrotron emission at these wavelengths is a diagnostic of particles several orders of magnitude higher in energy and correspondingly shorter in lifetime than those pro…
