High-resolution x-ray telescopes
S. L. O'Dell, R. J. Brissenden, W. N. Davis +21
High-energy astrophysics is a relatively young scientific field, made possible by space-borne telescopes. During the half-century history of x-ray astronomy, the sensitivity of foc…
Atmospheric Phase Correction using CARMA-PACS: High Angular Resolution Observations of the FU-Orionis star PP 13S*
Laura M. Pérez, James W. Lamb, David P. Woody +16
We present 0.15" resolution observations of the 227 GHz continuum emission from the circumstellar disk around the FU-Orionis star PP 13S*. The data were obtained with the Combined…
ProtoEXIST: Advanced Prototype CZT Coded Aperture Telescopes for EXIST
Branden Allen, Jaesub Hong, Josh Grindlay +9
{\it ProtoEXIST1} is a pathfinder for the {\it EXIST-HET}, a coded aperture hard X-ray telescope with a 4.5 m CZT detector plane a 9070 degree field of view to be flown…
Science drivers and requirements for an Advanced Technology Large Aperture Space Telescope (ATLAST): Implications for technology development and synergies with other future facilities
Marc Postman, Tom Brown, Kenneth Sembach +11
The Advanced Technology Large-Aperture Space Telescope (ATLAST) is a concept for an 8-meter to 16-meter UVOIR space observatory for launch in the 2025-2030 era. ATLAST will allow a…
Using ACIS on the Chandra X-ray Observatory as a particle radiation monitor
C. E. Grant, B. LaMarr, M. W. Bautz +1
The Advanced CCD Imaging Spectrometer (ACIS) is one of two focal-plane instruments on the Chandra X-ray Observatory. During initial radiation-belt passes, the exposed ACIS suffered…
AXTAR: Mission Design Concept
Paul S. Ray, Deepto Chakrabarty, Colleen A. Wilson-Hodge +18
The Advanced X-ray Timing Array (AXTAR) is a mission concept for X-ray timing of compact objects that combines very large collecting area, broadband spectral coverage, high time re…
