摘要
The Physics of the Accelerating Universe (PAU) is a new project whose main goal is to measure the baryon acoustic oscillations (BAO) in the galaxy distribution to characterize dark energy. For this purpose, it will build a new large field of view camera (the PAU Camera) to carry out a wide area imaging survey with narrow band filters spanning the optical wavelength range. The PAU Camera is at an early stage of design. Currently., it is designed to have a focal plane field of view of approximately 45cm in diameter, that will be densely populated by state of the art CCDs. The PAU Camera will use a new set of approximately 45 narrow band filters ranging front similar to 4200 to similar to 8700 angstroms with two additional wide band filters at the blue and red ends of the spectrum. The camera will operate in drift-scan mode. The PAU Camera, is expected to be mounted either in a purposely designed 2.5m class wide field telescope or in an existing telescope that could be adapted to deliver a wide field.
