Steward Sabbatical Visitor Involved in Image Processing of the Pluto Photos

Tod R. Lauer, an astronomer at the National Optical Astronomy Observatory, is taking a sabbatical at Steward Observatory this year.  As part of his research program he has been working on a variety of image processing problems in support of the New Horizons mission to Pluto.  During the first part of his sabbatical Lauer developed tools to recover sharp details from the distant New Horizons encounter observations.  As the attached story explains, Lauer was also involved in the final reduction of the Pluto images obtained by New Horizons at its time of closest approach to that distant world. Come see Tod, currently in Room N205C, if you want to talk about algorithms and/or image processing, two of his loves.

Ammonia in Starless Cores

Steward Observatory graduate student Youngmin Seo has published that largest map of the molecule ammonia in space using the 100 meter Green Bank Telescope (GBT). The ammonia molecule is an excellent probe of cold, dense molecular gas in star-forming regions via the radiation it emits at 1.3 centimeters in the radio part of the spectrum. The observations map ammonia in...
