Roberto Abraham’s research focuses on galaxy evolution over a time span of about 11 billion years, and tries to answer questions such as: What did galaxies look like when the Universe was young? How can we best describe galaxies in a quantitative way? How do changes in galactic structure map onto ideas for the underlying physics of galaxy evolution?
In order to answer such questions, Abraham uses adaptive optics systems on large telescopes to study the evolution of galaxy sizes over cosmic time. Also, in partnership with Yale University, he has built a novel telescope array in New Mexico called Dragonfly to image very faint structures in nearby galaxies.
