Running a distributed virtual observatory: US Virtual Astronomical Observatory operations [PDF]

open access: yes, 2012
Operation of the US Virtual Astronomical Observatory shares some issues with modern physical observatories, e.g., intimidating data volumes and rapid technological change, and must also address unique concerns like the lack of direct control of the underlying and scattered data resources, and the distributed nature of the observatory itself.

THE ZADKO OBSERVATORY [PDF]

open access: yesRevista Mexicana de Astronomía y Astrofísica Serie de Conferencias, 2021
The 1.0 metre f/4 fast-slew Zadko Telescope was installed in June 2008 approximately seventy kilometres north of Perth at Yeal, in the Shire of Gingin, Western Australia. Since the Zadko Telescope has been in operation it has proven its worth by detecting numerous Gamma Ray Burst afterglows, two of these being the most distant 'optical transients ...

Gravitational observatories

open access: yesJournal of High Energy Physics, 2023
Abstract We consider four-dimensional general relativity with vanishing cosmological constant defined on a manifold with a boundary. In Lorentzian signature, the timelike boundary is of the form σ × ℝ, with σ a spatial two-manifold that we take to be either flat or S2. In Euclidean signature we take the boundary to be S2 × S1.
