Arnica: the Arcetri Observatory Nicmos 3 Imaging Camera
ARNICA (ARcetri Near Infrared CAmera) is the imaging camera for the near infrared bands between 1.0 and 2.5 m that Arcetri Observatory has designed and built as a general facility for the TIRGO telescope (1.5 m diameter, f/20) located at Gornergrat (Switzerland). The scale is 100 per pixel, with sky coverage of more than 40 40 on the NICMOS 3 (256 256 pixels, 40 m side) detector array. The opti...
متن کاملThe Synthesis Telescope at the Dominion Radio Astrophysical Observatory
We describe an aperture synthesis radio telescope optimized for studies of the Galactic interstellar medium (ISM), providing the ability to image extended structures with high angular resolution over wide fields. The telescope produces images of atomic hydrogen emission using the 21-cm H i spectral line, and, simultaneously, continuum emission in two bands centred at 1420MHz and 408MHz, includi...
متن کاملScience with Virtual Observatory Tools Astrophysical Virtual Observatory Scientist
The Virtual Observatory is now mature enough to produce cutting-edge science results. The exploitation of astronomical data beyond classical identification limits with interoperable tools for statistical identification of sources has become a reality. I present the discovery of 68 optically faint, obscured (i.e., type 2) active galactic nuclei (AGN) candidates in the two GOODS fields using the ...

متن کاملThe Smithsonian Astrophysical Observatory Solar Constant Program
The Astrophysical Observatory of the Smithsonian Institution (APO) made measurements of the solar constant at many locations on the earth's surface from 1902 to 1962. These measurements have been interpreted by various authors to show that the sun has both a long-term secular change in brightness and cyclic variations. The same data set has been used by other authors to show that the sun is con...
