Dr. Margaret Geller at Smithsonian has released a new redshift survey of a rich galaxy cluster, the first substantial spectroscopic survey of this cornerstone of extragalactic research. Read more.
The MMTO has an opening for an Electronic Technician, Sr. (job #54182). Details and an online application can be found here.
The observing schedule for January through April is posted, along with Program Titles.
On Tuesday, December 10, at 7:11pm, a sonic boom hit Tucson as a large meteor passed overhead. MMT's all sky camera captured its bright flash in a single image. The frame shows the moon (center) and the meteor (upper).
Work began in October on the installation of a new comprehensive fire alarm system at all of the facilities on Mount Hopkins. Work remaining at the MMT is expected to be completed by mid-December. Work continues at the other mountain facilities and at the Administrative Complex at the basecamp area.
Construction improvements at the Common Building began in November and are expected to be finished in December. The work includes sealing leaks, repairing interior drywall in the basement, and touching up exterior paint.

Using publicly available data from the AGN and Galaxy Evolution Survey (AGES), conducted at the MMTO with the hectospec instrument, researchers have discovered seven new candidates for dual supermassive black hole systems in the centers of galaxies. Based on the new findings, they suggest that the number of galaxies containing dual supermassive black holes decreases over time, likely because more galaxies merged together in the past. AGES is a joint Arizona/CfA collaboration.

Using the hectospec instrument at the MMTO, astronomers are studying the mass distribution in galaxy clusters. The basic techniques were developed by M. J. Geller (Smithsonian Astrophysical Observatory) and her collaborators some time ago. The data are now good enough to get excellent results for a large sample of clusters. Read more.
