Overview and status of the Giant Magellan Telescope Project

Abstract: The Giant Magellan Telescope project is proceeding with design, fabrication, and site construction. The first of the seven required 8.4-m primary mirror segments is completed and in storage, three segments are in various stages of grinding and polishing, and the fifth segment has been cast. Industry contracts are underway to complete the design of the telescope structure. Residence buildings and other facilities needed to support construction at the Las Campanas site in Chile are complete. Hard rock excavation… Show more

“…Moreover, I prove that SPADE can approach the optimal precision allowed by quantum mechanics in estimating the location and scale parameters of a subdiffraction object. Given the usefulness of moments in identifying the size and shape of an object [26], the proposed scheme, realizable with far-field linear optics and photon counting, should provide a major boost to incoherent imaging applications that are limited by diffraction and photon shot noise, including not only fluorescence microscopy [27][28][29][30] and space-based telescopes [31] but also modern ground-based telescopes [32][33][34][35].…”

“…An observatory like SPICA as presented in this paper, with a large, cold telescope complemented by an instrument suite that exploits the sensitivity attainable with the low thermal background, can in the mid/far-infrared achieve a gain of over two orders of magnitude in spectroscopic sensitivity as compared to Herschel, Spitzer and SOFIA (Becklin et al, 2016, see also Figure 4). In addition such a mission will provide access to wavelengths well beyond those accessible with the James Webb Space Telescope (JWST Gardner et al, 2006) and the new generation of extremely large telescopess (Tamai et al, 2016;McCarthy et al, 2016;Cohen, 2016). Sitting squarely between JWST and ALMA (Wootten & Thompson, 2009), SPICA will enable the discovery and detailed study of the coldest bodies in our Solar System, emerging planetary systems in the Galaxy, and the earliest star forming galaxies and growing super-massive black holes -a gigantic leap in capabilities for unveiling the 'hidden Universe'.…”

“…Prior to polis 1 • The Software Configurable Optical Test System (SCOTS) is a deflectometry system that measures slopes over the full aperture with high spatial resolution and dynamic range. [11], [12] The slopes are integrated to give a full surface measurement with high accuracy for periods up to 2-3 m. • The scanning pentaprism test is the main independent verification of off-axis geometry and large-scale figure.…”

“…The 25 m GMT primary mirror consists of seven 8.4 m lightweight honeycomb mirrors. [1]- [3] The honeycomb design provides the stiffest and lightest large mirrors ever made, minimizing deflection due to gravity and wind. The use of 8.4 m segments guarantees a smooth wavefront over large fractions of the aperture and, together with the segmented adaptive secondary mirror, simplifies alignment and phasing of the telescope.…”
