The emission distribution in SS433
International Conference Recent Advances in Natural Language Processing, RANLP (2006)
Abstract:
We present the results from a large observing campaign where we obtained 61 medium resolution spectra spread over three months. We thus cover roughly five orbits and about half a precession phase. In this paper we describe the analysis of the so-called "stationary" emission lines, which we use to compute Doppler-maps of the emission distribution in the SS433-system. The radial velocities of the individual line components have been analysed. Periodic variations with the orbital period are confirmed, but also variations on longer timescales are found. These long-term variation might be either either related to the precession phase or to some transient phenomen.Concepts in thermal physics

Abstract:
This modern introduction to thermal physics contains a step-by-step presentation of the key concepts. The text is copiously illustrated and each chapter contains several worked examples.Extended inverse Compton enussion from distant powerful radio galaxies
ESA SP PUBL 604 (2006) 611-612
Abstract:
Chandra observations of 3C432, 3C191 and B2 0902+34 are presented as part of an ongoing search for inverse-Compton scattering of the cosmic microwave background (CMB) from high redshift radio sources (Schwartz, 2000). The energy density of the CMB increases with redshift, z, as (1 + Z)(4), so the relatively high redshift of these powerful radio galaxies makes them good candidates for detecting extended inverse-Compton scattering along the radio jet axis: we do indeed detect radio-aligned X-ray emission.On the Binary Nature of SS 433
