It could be that SETI signals have arrived at the Earth, but are lower then the noise level, and our receivers cannot detect them. ... Fig. ... It follows that two zones form around the star with civilization X: "Zone Yes", where its SETI signal can be detected, and "Zone No", where its signals are hidden by noise (Fig. ... In practice, it is more efficient to use a time factor, since the problem of SETI contact does not limit the duration of the signal element and semantic text. ...

... 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. ...

Abstract -- Abundances of heavy elements decreases with increasing galactocentric distance almost in all disk galaxies. ... To explain this gradient in young objects and in the interstellar gas one has to assume that a typical disk galaxy is an open system, i.e. it expels some synthesized heavy elements into the circumgalactic space and/or accretes intergalactic gas with zero metallicity, with rates of both processes depending on the galactocentric distance. ...
