... Abstract: We present an extensive study of the radiative transfer in dusty galaxies based on Monte Carlo simulations. ... We have explored the dependence of A_l on a conspicuous set of quantities (Hubble type, inclination, dust optical thickness, dust distribution and extinction properties) for a large wavelength interval, ranging from 1250A to the K band, thus finally providing a comprehensive atlas of dust extinction in galaxies, which is electronically available. ...

Next: CCD Scientific Performance Up: CCD Operation Previous: CCD Operation . A visible light photon releases only one electron-hole pair, and consequently many photons must be collected in each pixel for a measurable signal to be produced. ... This use as an imaging X-ray spectrometer requires that no more than one photon is incident on each pixel in any image frame, which imposes a requirement that image collection times be limited to ~seconds for typical astronomical applications. ...

Our calculations show that although the Newtonian model works very well for almost all practical purposes for the well known showers during present epochs, there could be some exceptional combinations of orbital elements for which the general relativistic precession in argument of pericentre and its influence on nodal distances could become significantly pronounced and decisive for predicting any earth-meteor intersection. ...
