Laboratory for High Energy Astrophysics ( LHEA )

The Laboratory was reorganized in October 1995 into two science and two technical support branches. The science branches are the "X-ray Astrophysics Branch" and the "Gamma Ray and Cosmic Ray Astrophysics Branch".

LBT Telescope

The Large Binocular Telescope (LBT) is a collaboration between the University of Arizona, the Italian astronomical community, which is represented by the Arcetri Astrophysical Observatory in Florence, and the Research Corporation in Tucson. The goal of the LBT project is to construct a binocular telescope consisting of two 8.4-meter mirrors on a common mount. This telescope will be equivalent in light-gathering power to a single 11.8-meter instrument. Because of its binocular arrangement, the telescope will have a resolving power (ultimate image sharpness) corresponding to a 23-meter telescope.
