... Future seminars . P a s t seminars . ... Stochastic Particle Acceleration and the Problem of Background Plasma Overheating " . D.O. Chernyshov and V.A. Dogiel (P.N.Lebedev Institute of Physics) . ... It was concluded also from these investigations that it is problematic to produce emitting electrons from a background plasma by stochastic (Fermi) acceleration because the energy supplied by external sources in the form of Fermi acceleration is quickly absorbed by background plasma. ...

... Programme . ... Abstract: Chandra data taken as part of the Very Large Program (VLP) show that the X-ray spectrum in Centaurus A's jet steepens with increasing distance from the jet axis. ... Electrons with sufficient energy to emit synchrotron X-rays must be accelerated locally to the knots, since their energy loss timescale is short compared with any dynamical timescale associated with fluid motion. ...

We cannot observe the way the distant universe accelerates cosmic rays or produces energetic photons, but acceleration processes also occur on our Sun , though on a much more moderate scale. ... That is why such events are often missed by cosmic ray detectors near the equator, where the lowest energies are excluded by the Earth's magnetic field. The best detectors for observing solar particles are therefore those sensitive to the lowest energies of the cosmic radiation. ...

Nongravitational Effects on Cometary Motion due to Jupiter . ... The problem of linking cometary apparitions before and after the approach of a comet to Jupiter was investigated. A hypothesis of possible existence of additional acceleration, perturbing the motion of comets in the vicinity of Jupiter, was considered. This nongravitational perturbation is described by a function of the jovicentric distance, written in a standard "force law" form. ...

... Home . ... Data . ... Data Analysis . ... CTE . ... We have developed a method to measure the counts in cosmic ray trails (CRTs), which result from imperfect charge transfer efficiency (CTE). ... Analysis of the CRTs reveals that some charge is trapped and released on short timescales (~seconds or less), although the charge in CRTs does not account for all observed CTE losses. The time dependence of Y-CTE and X-CTE are shown for WFPC2 and STIS using the STScI archive of dark calibration frames. ...

... Astronomical and WVR beams . ... Using high-resolution three-dimensional realisations of turbulent fields, we investigate the limits on achievable performance of atmospheric phase correction using water-vapour radiometers arising from following effects: the incoherent measurement of power from water by the radiometers (in contrast to coherent detection of the astronomical signal); the different tapers of the response patterns of the astronomical and radiometer receivers; and, the ...
