Proposal Deadlines for Trimester 2010B (1st May 2010 – 19th July 2010)

Construction at the MMT

Construction began on January 11, 2010 on an Instrument Repair Facility at the MMT summit.  It is scheduled to be completed by summer.  Construction is taking place during the weekdays between 8:00am – 5:00pm.  There are no plans for work to be done on weekends.  The construction site is cordoned off with cones or is within a chained-off area.

MMTO is looking for an Adaptive Optics Scientist/Engineer

The MMT Observatory (MMTO), a joint venture of the Smithsonian Institution and the University of Arizona, is seeking a Scientist or Engineer with working knowledge of astronomical adaptive optics to join the MMT team. The MMTO operates a 6.5-meter telescope at the summit of Mt. Hopkins (elevation 8550 feet), some 40 miles south of Tucson in southern Arizona. Additional details regarding the telescope and associated instrumentation may be found via the web site: http://www.mmto.org.

Research Using the MMT in the News

From observations made using the MMT, Dr. E. Mamajek of the University of Rochester has discovered that the first known binary star is actually a sextuplet system.   To read the article published by Science Daily, press here.

The New Red Channel Detector

The installation and testing of a new detector for Red Channel has been completed by the UofA’s Imaging Technology Laboratory (ITL). The new device has 15-micron pixels and a format of 520 x 1032 pixels (spatial x dispersion). The read noise of the detector is 3.5 electrons. The measure QE for the detector is provided below. ITL’s web page ( http://uao.itl.arizona.edu) provides additional details and information.
