Tarsh Freeman

Tarsh Freeman

Bevill State Community College

Tarsh Freeman received his BS degree from the University of Alabama in Mathematics with a minor in Physics, and then later received a masters degree in Mathematics. However, prior to this he got an "education" broader than Dr. Byrd's in that he has worked both in a tire manufacturing plant in Tuscaloosa and as an Alabama State Trooper (after attending the Alabama State Trooper Academy). After gaining this experience, he decided to obtain a degree at the University of Alabama. His interest in astronomy stems from several courses taken at the University. After graduation, he taught mathematics at Stillman College in Tuscaloosa and at the University. He now is a faculty member at Bevill State Community College, teaching mathematics at at the Fayette, Jasper, and Carrolton, Alabama campuses. He continues to tutor mathematics to Alabama athletes in all sports in the University Athletic Academics department. He continues to be an enthusiastic weight lifter having won several state wide competitions in power lifting, ``deadlifting" over 600 pounds (about 30 years ago). In collaborative research with Gene Byrd and Sethanne Howard in the early 90's, Tarsh managed to successfully simulate the two-way arm pattern of NGC 4622 with a single inner leading arm and an outer pair of trailing arms being created by a plunging passage of a smaller perturber galaxy through NGC 4622's disk. The inner leading arm matched theoretical expectations for a galaxy with a flat rotation curve. Later, once the HST images and spectroscopic data had been obtained for NGC 4622, it became possible to determine the actual arm winding sense for this galaxy. The universe had a surprise in store for them. When the HST images were obtained they showed immediately that the theoretical expectations were apparently wrong and the outer pair of arms have the leading sense, winding outward in the same direction the disk turned, clockwise. NGC 4622 appears to be even more unique than previously thought.
