Explosion Illuminates Invisible Galaxy

For followup details on the recent exciting observation noted here previously of an optical afterglow of a distant gamma ray burst, observed in part with the MMT's Blue Channel Spectrograph, click here.

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.
