The collaboration has finalised a detailed background model offering the lowest index ever obtained, and has also adopted a new technology: NTL light detectors, which are much more effective at rejecting background noise.
A model based on the concept of quantum measurement provides a new approach to calculate diffraction. The predictions of wave optics and the quantum model are significantly different at large angles.
To study dark energy, the large Dark Energy Spectroscopic Instrument (DESI) will map over 40 million galaxies. Today, DESI has released its first data and is publishing 15 papers on the scientific study of these data.
