... Up: Future Instruments and Telescopes, Tools . ... New Generation Astronomical Telescopes (NGAT), a class of telescopes designed to be operated remotely and robotically, require efficient methods for communicating images over heterogeneous and low-bandwidth data networks such as the Internet. ... Methods researched thus far involve the classification of astronomical images based on object parameterisation, progressive image transmission, and evaluation of existing image compression schemes. ...

In the literature, there is an ambiguity pertaining to the existance of a far-IR excess in RS CVn systems. ... We found 72 acceptable detections in the 12mu band, and 40 in the 25mu band (50% more than the IRAS Point Source Catalog). ... Furthermore, at the higher wavelength bands the IRAS angular resolution drops from 0.5 arcmin at 12mu to 2 arcmin at 100mu and the background becomes very complex so one cannot be certain about the origin of the observed flux. ...

... Programme . ... Abstract: Interferometric observations in the mid-infrared made studies of the central dusty tori of Active Galactic Nuclei (AGNs) possible and proved their existence in a number of nearby AGNs. Our first results on Centaurus A (NGC 5128) showed that nuclear dust also exists in the innermost parsec of this galaxy (Meisenheimer et al. ... Its minor axis is oriented almost perfectly parallel to the radio jet. ...

In using what-if questions in the classroom, it is worth bearing in mind that students extrapolating the effects of new scenarios will encounter two different situations: direct changes to the new version of Earth and indirect changes resulting from the direct changes. ...

... Email: chaos@mail.cplire.ru . ... We investigate phenomena on the edge of spatially homogeneous chaotic mode and spatiotemporal chaos in a lattice of chaotic 1-D maps with local connections. We show that spatially homogeneous chaotic mode cannot exist in a lattice with local connections if the Lyapunov exponent of the isolated chaotic map is greater than some critical positive value. We propose a few schemes that make spatial synchronization possible in large lattices. ...

...

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. ...
