The Scientiic Potential for Astronomy from the Antarctic Plateau Australian Working Group for Antarctic Astronomy
1 Figure 1: Map of Antarctica and the Australian Antarctic Territory. This sketch map shows the location of sites being considered for astronomy on the high plateau (Dome A, Dome C, South Pole and Vostok), as well as the Australian bases along the coast, Casey, Davis and Mawson, and the US base at McMurdo. 2 Executive Summary Our knowledge of the universe comes from recording the photon and par...
متن کاملInfrared Detector Arrays for Astronomy
Use of infrared detector arrays in astronomy began roughly 20 years ago, and our detection capabilities in parts of this spectral range have doubled about every seven months since then. A variety of approaches are now used for detector arrays operating from 1 μm to 1 mm and beyond. They include direct hybrid arrays of InSb and HgCdTe photodiodes that operate from 0.6μm to 5μm, and of Si:As impu...
متن کاملASTRONOMY AND ASTROPHYSICS New infrared
We present optical spectra for new infrared Seyfert galaxies obtained with the 2.16m telescope at Beijing Astronomical Observatory (BAO). After wavelength and flux calibration, they are classified by the degree of nuclear activity: nine Seyfert 2 and three Seyfert 3 galaxies. In addition, by using the data from de Grijp et al.(1992), we find that (1) there exists a tight correlation between lum...
متن کاملDeveloping Metal Mesh Filters for Mid-Infrared Astronomy of 25 to 40 micron
We have developed bandpass filters for long mid-infrared astronomy in 25 to 40μm. Most of materials become opaque in wavelengths longer than 25μm. We have applied the metal mesh method to make filters of non-transparent materials. The mesh patterns are designed based on the FDTD calculations and fabricated by the photolithography method. Measured transmittances of the fabricated filters agree w...
متن کاملAmerican Astronomical Society – Division on Dynamical Astronomy
Currently, there are more than 100 confirmed multiple-planet systems. Moreover, a recent study by Kepler has identified 361 multiple-planet candidate systems. Investigating these systems would give us an important clue in understanding formation and evolution of planetary systems. In such multiple-planet systems, secular interactions among planets could play a significant role in determining th...
