21 Mar 2013 | | Abstract: | RadioAstron is a Russian space based radio telescope with a ten meter dish in
a highly elliptical orbit with an eight to nine day period. RadioAstron works
together with Earth based radio telescopes to give interferometer baselines
extending up to 350,000 km, more than an order of magnitude improvement over
what is possible from earth based very long baseline interferometry. Operating
in four frequency bands, 1.3, 6, 18, and 92 cm, the corresponding resolutions
are 7, 35, 100, and 500 microarcseconds respectively in the four wavelength
bands. | | Source: | arXiv, 1303.5200 | | Services: | Forum | Review | PDF | Favorites | |
