Description:

Speaker: Dr. Benne Holwerda (University of Louisville)

One of the largest spiral galaxies in the known local universe, UGC 2885, was recently nicknamed Rubin’s Galaxy in honor of Dr. Vera Rubin, who studied its rotation in the 1980s and found evidence for the existence of dark matter. A new, 74-megapixel, mosaic image of the galaxy from the Hubble Space Telescope was released in January.

Dr. Benne Holwerda of the University of Louisville will present “Rubin's Galaxy: A Gentle Giant Spiral Galaxy” on Wednesday, June 3, 2020 at 3:30 pm EDT, to describe his observations and how the large galaxy provides an intriguing test of the observed scaling relationships between the characteristics of a galaxy and the characteristics of its globular star cluster population.

Recorded live on Wednesday, June 3, 2020.
