Precise Astronomical Flux Calibration and its Impact on Studying the Nature of Dark Energy
Christopher W. Stubbs, Yorke J. Brown
Measurements of the luminosity of type Ia supernovae vs. redshift provided the original evidence for the accelerating expansion of the Universe and the existence of dark energy. De…
A Method for Establishing a Station-Keeping, Stratospheric Platform for Astronomical Research
Robert Fesen, Yorke Brown
During certain times of the year at middle and low latitudes, winds in the upper stratosphere move in nearly the opposite direction than the wind in the lower stratosphere. Here we…
Precision Calibration via Artificial Light Sources Above the Atmophere
Justin E. Albert, Maxwell H. Fagin, Yorke J. Brown +3
Deeper understanding of the properties of dark energy via SNIa surveys, and to a large extent other methods as well, will require unprecedented photometric precision. Laboratory an…
Precise Throughput Determination of the PanSTARRS Telescope and the Gigapixel Imager using a Calibrated Silicon Photodiode and a Tunable Laser: Initial Results
Christopher W. Stubbs, Peter Doherty, Claire Cramer +5
We have used a precision calibrated photodiode as the fundamental metrology reference in order to determine the relative throughput of the PanSTARRS telescope and the Gigapixel ima…
Preliminary Results from Detector-Based Throughput Calibration of the CTIO Mosaic Imager and Blanco Telescope Using a Tunable Laser
Christopher W. Stubbs, Sara K. Slater, Yorke J. Brown +7
We describe the scientific motivation for achieving photometric precision and accuracy below the 1% level, and we present a calibration philosophy based on using calibrated detecto…
