An 8–14 Micron Infrared Astronomical Photometer

Two-dimensional silicon vidicon astronomical photometer.

We have developed and successfully used an integrating two-dimensional silicon diode array vidicon photometer which is exceptionally well suited for use with telescopes. The video signal is read out from the 1-cm silicon target of the vidicon through a current mode preamplifier and then converted to digital form and stored on magnetic tape. The 256 x 256 element frames are recorded at 20,000 ei...

Apochromatic lenses for near-infrared astronomical instruments

Deqing Ren Jeremy R. Allington-Smith University of Durham Department of Physics Durham DH1 3LE United Kingdom E-mail: [email protected] Abstract. A method based on the Herzberger approach has been investigated for the selection of glasses for the apochromatic correction at near-infrared (NIR) wavelength. The method avoids the algebraic complexity and simplifies the glass selection process...

The natural product fumagillin exhibits potent antiproliferative and antiangiogenic properties. The semisynthetic analog PPI-2458, [(3R,4S,5S,6R)-5-methoxy-4-[(2R,3R)-2-methyl-3-(3-methylbut-2-enyl) oxiran-2-yl]-1-oxaspiro[2.5]octan-6-yl] N-[(2R)-1-amino-3-methyl-1oxobutan-2-yl]carbamate, demonstrates rapid inactivation of its molecular target, methionine aminopeptidase-2 (MetAP2), and good eff...

Near—infrared sky brightness monitor for the South Pole

The antarctic plateau has the potential for being the best site on Earth for conducting astronomical observations from the near-infrared to the sub-millimeter. Particular gains are expected in the 1 to 5 micron region, where the high altitude, low water vapour content, and low thermal emission from the atmosphere combine to create observing conditions unequalled elsewhere on the surface of the ...
