Evidence for Densest Nearby Galaxy

The MMT was one of the ground-based telescopes, along with the Hubble Space Telescope and the Chandra X-ray Observatory, used in studying a nearby and very dense galaxy, M60-UCD1. Read NASA's press release and the paper

Dual Supermassive Black Hole Candidates

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.

Studying the Mass Distribution in Galaxy Clusters

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.

Explosion Illuminates Invisible Galaxy

Results from MMTPol

A new MMTPol image of IRC+10420, a yellow hypergiant star located in the constellation of Aquila, reveals the unusual nature of this object, one of the most luminous stars known. The imaging polarimeter, originally commissioned at the MMT at the end of 2011 and fed by the MMT's adaptive optics secondary mirror, shows that IRC+10420 is likely enshrouded in a narrow cone of dust.

A Video Visit to the MMT Observatory

For a behind-the-scenes visit to the MMT Observatory, take a look at a video appearing in Astronomy magazine's blog at The video was created by Jason Davis, a science journalism graduate student at the U of A.

MMT Spectroscopy

On June 7, R. Lunnan and collaborators from Harvard/CfA detected the optical afterglow of a distant gamma ray burst with the MMT's Blue Channel Spectrograph only seven hours after the alert went out from the Burst Alert Telescope.  More information about the detection can be found here

Supernova 2012au: First published results from MMTCam

A recently commissioned (Nov. 2012) capability at the MMT includes filtered imaging with MMTCam. A new publication by D. Milisavljevic (Harvard-Smithsonian Center for Astrophysics) and colleagues on the slowly-evolving supernova 2012au, includes the first published results from MMTCam. Data from MMT Blue Channel Spectrograph was also included in the paper.
