We report on the discovery of a new potential galaxy threshing system in the COSMOS 2 square degree field using the prime-focus camera, Suprime-Cam, on the 8.2 m Subaru Telescope. This system consists of a giant elliptical galaxy with MV ≈ −21.6 and a tidally disrupted satellite galaxy with MV ≈ −17.7 at Based on data collected at Subaru Telescope, which is operated by the National Astronomical...

Detectors play a key role in an astronomical observatory. In astronomy, the role of the telescope and instrument is to bring light to a focus in effect, the telescope-instrument act as “spectacles”. The detectors, meanwhile, have the critical role of sensing the light the detectors are the “eyes” of an observatory. The performance of an astronomical observatory is directly dependent upon the pe...

Haystack Observatory is a multidisciplinary research center located in Westford, MA, 40 miles northwest of the MIT campus. The observatory conducts astronomical studies using radio techniques, geodetic measurements using Very Long Baseline Interferometry (VLBI), and atmospheric observations using high-power incoherent scatter radar. An important component of Haystack’s mission is the education ...
