Physics

Scientific paper

The Supernova/Acceleration Probe (SNAP) is designed to measure the time-dependent equation of state of the dark energy component. The expansion rate of the Universe since z=1.7 will be determined to percent-level accuracy using high-precision measurements of Type Ia supernovae and weak gravitational lensing. SNAP is a 2-meter telescope in high Earth orbit, equipped with a 0.5-Gigapixel visible/near-IR imager and a visible/near-IR spectrograph. I will give an overview of the goals, design, and current status of SNAP, and describe the expected sensitivity of the experiment to evolution of the dark energy.
