This book deals with the fundamentals of stellar interferometry with emphasis on aperture synthesis using sparse array of telescopes particularly at optical/IR wavelengths, the origin, properties, and optical effects of turbulence in the Earth's atmosphere, techniques developed to overcome image degradation. Studded with more than one hundred and fifty illustrations and tens of footnotes, it addresses the basic tricks of trade, current trend, motivation, methods, and path to future promise of true interferometry both from the ground and space. Also discussed are the technical challenge involved, such as beam transportation and recombination, detecting fringes using modern sensors, and image synthesis. Astronomical science that benefits from aperture synthesis imaging are highlighted as well.The near-IR polarimetric data obtained at the VLT and Subaru telescopes by Murakawa et al. (2008b) ... 22.214.171.124 The Galactic Center The galactic center is the rotational center of the Galaxy (Reid 1993; Eisenhauer et al. 2003), which is ... To note, gas emits X-rays when heated to extremely hot temperatures, while dust, which is cooler than stars or gas, emits a continuum ... They have produced an IR luminosity function and color-magnitude diagram for 70 stars down to mv a#39;19.5 mag.
