MMT Data used in Discovery of Unprecedented Supermassive Black Hole

Astronomers from Peking University in China and the University of Arizona have discovered the most luminous quasar known at a redshift of greater than 6. The ultra-luminous quasar has a black hole that clocks in with a mass of about 12 billion times the mass of the Sun. This incredible object was discovered and characterized in part with the Red Channel Spectrograph at the MMT. Its existence is a challenge for current theories of black hole formation and growth and may support claims that supermassive black holes grew much more quickly in the early universe in comparison to their host galaxies.

Coldest Variable Brown Dwarf Discovered

A recent paper by reserachers at Arizona State University shows the discovery of the coldest variable brown dwarf published to-date. The astronomers used the SWIRC instrument to monitor four brown dwarfs over multiple epochs. One of those showed significant variability. These ultracool dwarfs are important evolutionary links between giant planets and the lowest mass stars, and their atmospheres will continue to be investigated further with larger surveys.

Observing Schedule

The observing schedule for January - April 2015 is posted along with Program Titles.

Week of Dec. 8 - Work on Mt. Hopkins Rd. - Revised

Due to continued roadwork, restrictions will be in place on Dec. 8-9 with road openings at 8:00-8:30am, noon-12:30, and after 4:00pm. On Dec. 10 & 11, the road will close at 8:30am and reopen at 4:00pm each day while work is done around km 9. A walk-through will be in place with vehicles available on either side. On Dec. 12, there will again be restrictions with the road open at 8:00-8:30am, noon-12:30, and after 4:00pm. Call 520-879-4422 for recorded updates.

Dec. 3-4: Roadwork on Mt. Hopkins

Culvert replacement will be conducted around km 7 on December 3 & 4, resulting in an overnight closure of the road at that area. The road will close at 8:30am on Dec. 3 and reopen after 4:00pm on Dec. 4. A walk-through will be in place with vehicles available on either side for use by observers and staff.  Current plans are for restrictions to be in place on Dec. 5, with road openings at 8-8:30am, noon-12:30, and after 4:00pm.

Local County is Proactive about Lighting

Cochise County, Arizona, has recently updated its lighting codes with the latest lighting technology in mind. The result is more protection for observatories and astronomy, while allowing enough light for the needs of businesses. Read about the county leading the way in the state!
