We report on the optical observations of the γ-ray pulsar PSR1706−44 performed with the Test Camera of the VLT-UT1 during the telescope Science Verification programme. With a limiting magnitude of V ∼ 27.5, these are the deepest optical observations ever performed for this pulsar, for which, however , no likely counterpart has been detected. The non-detection of PSR1706−44 sets an upper limit o...

2014 A kinetic equation, which includes the effects of degeneracy, is derived for dilute, polarized systems by the Green’s function method of Kadanoff and Baym. When the Born approximation is used for the self-energy, the equation reduces to a result due to Silin. In the Boltzmann limit our result is equivalent to the equation of Lhuillier and Laloë, with the addition of a mean-field drift term...
