Dynamical chaos in the problem of magnetic jet collimation O. Yu. ... In the paper of Bisnovatyi-Kogan (2007) magnetic collimation resulting from torsional oscillations of a cylinder with elongated magnetic field and periodically distributed initial rotation around the cylinder axis was considered. ... Space and time periods of oscillations depend on the conditions of jet formation: the length-scale, the amplitude of the rotational velocity, and the strength of the magnetic field. ...

A visual impression of the data used in the study. The relevant extra-galactic maps are represented as shells of increasing distance from Earth from left to right. ... After this are six shells containing maps of the millions of distant galaxies used in the study. These maps are produced using different telescopes in different wavelengths and are color-coded to show denser clumps of galaxies as red and less dense regions as blue. There are holes in the maps due to data quality cuts. ...

... Submitted by William Lee on 05/20/2007 15:10:19 . Side-by-side . Both scopes mounted on a Losmandy dual side-by-side (DSBS) plate. If you do this, be aware that balance is difficult if the two scopes are vastly different in weight (as in this case). I never considered this, but now I balance each scope individually on the DSBS and then the whole DSBS. I can demonstrate this, if anyone is interested. ...
