| This month’s speaker will be Dr. Nelson Caldwell of the Harvard Smithsonian CfA. Dr Caldwell is a member of the Optical and Infrared Astronomy Division which focuses on extragalactic and galactic astronomy emphasizing studies of the large-scale structure of the universe, clusters of stars and of galaxies. He will talk about two large observing projects which seek to understand the constituent stars and star clusters of the Andromeda galaxy (M31). The first is a Hubble study where he and his team have collected new images of about 1/3 of the galaxy’s disk in six different colors thus providing astronomers with the largest high resolution image of a nearby galaxy. The second is a project using the multi fiber spectrograph mounted on the MMT telescope in Arizona. More than 5000 spectra taken of stars and star clusters have allowed them to discover patterns of age and motion in these objects.
Please join us for a pre-meeting dinner discussion at Changsho, 1712 Mass Ave, Cambridge, MA at 6:00pm before the meeting. |
