... arXiv.org . astro-ph . ... Submitted: 2008-03-26 . With the aim of studying magnetic effects in time-distance helioseismology, we use the first-order Born approximation to compute the scattering of acoustic plane waves by a magnetic cylinder embedded in a uniform medium. ... We also show that, for arbitrary magnetic field strength, the Born approximation is not valid in the limit where the radius of the magnetic cylinder tends to zero.

The Charged Coupled Device (or CCD) was initially conceived in 1970 at Bell Labs by W. Boyle and G. Smith. ... Stored charged readout along the registers of the CCD would then allow this device to be a serial memory device. ... The charge transfer efficiency of this device was so low, that the overall yield was less than 0.5% (slightly less than good photographic plates at the time). ... Early observations with this CCD quickly showed its superiority over photographic plates. ...

We present a catalogue of galaxies for which spatially resolved data on their internal kinematics have been published; there is no apriori restriction regarding their morphological type. The catalogue lists the references to the articles where the data are published, as well as a coded description of these data: observed emission (E) or absorption (A) data, optical (O) or radio (R) data, velocity (V) or velocity dispersion (D), radial profile (1) or 2D field (2). ...
