abstract |
GravityCam is a new concept of ground-based imaging instrument capable of delivering
significantly sharper images from the ground than is normally possible without adaptive
optics. Advances in optical and near-infrared imaging technologies allow images to
be acquired at high speed without significant noise penalty. Aligning these images
before they are combined can yield a 2.5–3-fold improvement in image resolution. By
using arrays of such detectors, survey fields may be as wide as the telescope optics
allows. Consequently, GravityCam enables both wide-field high-resolution imaging and
high-speed photometry. We describe the instrument and detail its application to provide
demographics of planets and satellites down to Lunar mass (or even below) across the
Milky Way. GravityCam is also suited to improve the quality of weak shear studies
of dark matter distribution in distant clusters of galaxies and multiwavelength follow-ups
of background sources that are strongly lensed by galaxy clusters. The photometric
data arising from an extensive microlensing survey will also be useful for asteroseismology
studies, while GravityCam can be used to monitor fast multiwavelength flaring in accreting
compact objects and promises to generate a unique data set on the population of the
Kuiper belt and possibly the Oort cloud. |
