With large number of datasets now available through the Web, data-sharing ecosystems such as the Web Observatory have emerged. The Web Observatory provides an active decentralised ecosystem for datasets and applications based on a number Web Observatory sites, each of which can run in a different administrative domain. On a Web Observatory site users can publish and securely access datasets acr...

In this document we discuss the introduction of theoretical results and data, for example that generated by large scale numerical simulations, into ongoing virtual observatory (VO) activities. The whitepaper has two main target audiences. The first is the community of theorists who either wish to take the initial steps necessary to publish their results online, or who want to make their existin...

Large observatory projects (such as the Large Synoptic Sky Telescope (LSST), the Ocean Observatories Initiative (OOI), the National Ecological Observatory Network (NEON), and the Water and Environmental Research System (WATERS)) are poised to provide independent, national-scale insitu and remote sensing cyberinfrastructures to gather and publish “community”-sensed data and generate synthesized ...

As part of an initiative to reduce the size, weight, and complexity of radio astronomy receivers and to place the conversion from analog to digital signals as close to the telescope feed as possible, a prototype single-conversion, sideband-separating mixer receiver with a tunable local oscillator (LO) between 5 and 9 GHz has been built and tested. After straightforward gain and phase calibratio...
