Mario-Mateo-HeadshotThis is the audio recording of the 04/19 meet-up with Dr. Mario Matteo, professor of Astronomy at the University of Michigan.  In this meet-up, Dr. Matteo discusses the importance of instrumentation in cosmology and astronomy, including his own development of several powerful telescopes.  And Dr. Matteo also explains why some of his work challenges current models of dark matter as an explanatory reason of the distribution of mass in nearby galaxies.

Some of the highlights of the conversation:

(12:50) What is meant by measuring velocities when using a telescope, (20:00) The skepticism of dark matter as an explanation for the distribution of mass in galaxies, (36:50) The excitement over the Gaia Satellite Mission, (45:00) What is a dwarf galaxy, (49:10) How gravitation lensing is used as data, and (1:08:50) Why Dr. Matteo doesn’t speculate on dark energy.
