The Digital Sky Project: Prototyping Virtual Observatory

Astronomy is entering a new era as multiple, large area, digital sky surveys are in production. The resulting datasets are truly remarkable in their own right; however, a revolutionary step arises in the aggregation of complimentary multi-wavelength surveys (i.e., the crossidentification of a billion sources) . The federation of these large datasets is already underway, and is producing a major...

The Measurement of the Sky Brightness at Merate Observatory

We describe the problems met using the telescopes of Merate Observatory, the branch of Brera Astronomical Observatory. From the point of view of the data analysis, we discuss how to introduce a satisfactory correction of the variable extinction coefficient, giving also some examples. We also measured the sky brightness, obtaining V =18.2 mag/arcsec. The light pollution is responsible for such a...

High Energy All Sky Transient Radiation Observatory

The scientific discoveries made by H.E.S.S. during its first year of operation encourage a reexamination of the open problems in high energy astrophysics and of the capabilities of the atmospheric Cherenkov technique, which could be employed to address them. We report on an initial Monte Carlo exploration of a ground-based instrument for observing cosmologically distant high energy transient ph...
