Mapping dark matter from galactic ripples

(PhysOrg.com) -- Sukanya Chakrabarti, Ph.D., an assistant professor of physics for the Charles E. Schmidt College of Science at Florida Atlantic University, has developed a way to discover and map dark matter in galaxies. Chakrabarti’s paper, “A New Probe of the Distribution of Dark Matter in Galaxies,” analyzes observed ripples in the outskirts of galaxies to infer the density profile of the dark matter halo. Chakrabarti is presenting her results at this week’s meeting of the American Astronomical Society in Austin, Texas.
