A Remote Observatory for Geocoronal Hydrogen Emissions
… Near Space Interaction Regions (INSpIRe) observatory is an adaptable research facility that is designed to use Fabry-Perot interferometer (FPI) to study the faint Balmer series emissions of the terrestrial upper thermosphere and exosphere, collectively known as the geocorona. This …

Simulations for the International X-ray Observatory
… can be conducted with the International X-ray Observatory (IXO), or a similar next-generation X-ray observatory. A general purpose X-ray image simulator has been developed. It uses a modern cosmological simulation and cluster scaling relations to produce simulated cluster images that are well …

Full-profile inversion of ionospheric radar data from Arecibo observatory
Incoherent scatter radar (ISR) technique is used to probe the ionosphere and measure the key state parameters of the ionosphere in thermodynamic equilibrium, including its electron density, ion densities and compositions, electron and ion temperatures, and the associated drift velocities of …

Plasma line generation and spectral estimation from Arecibo Observatory radar data
… measurements can be conducted at the Arecibo Observatory, one of the most important centers in the world for research in radio astronomy, planetary radar and terrestrial aeronomy [Altschuler, 2002]. Although ISR measurements have been routinely taken at Arecibo since the early 1960s, full …

Stabilizing energy reconstructions of the surface detector at the Pierre Auger Observatory
At the Pierre Auger Observatory, ultra-high energy cosmic rays are measured through indirect measurements of the extensive air showers they induce. Accordingly, an energy reconstruction process must be undertaken. For the surface detector, the models utilized for energy reconstruction are empirical …
