Chasing Galaxies

Natural History;Apr2012, Vol. 120 Issue 4, p10
The article presents information on cosmologist Beatrice Tinsley and her work on the evolution of galaxies over billions of years. Until Tinsley started researching the topic, Edwin Hubble's research was the prevailing model for cosmology. Her 1967 PhD dissertation project was a simulation of an evolving galaxy which showed that galaxies do change, and her theories and work as a professor at Yale University provided the inspiration for other extragalactic researchers to pursue more work in this field. Tinsley died of melanoma in 1981, two weeks after submitting her final scientific article to The Astrophysical Journal where it was published unedited.
