Meet the Astronomer – Friday October 5 at 7pm

For years, cosmologists have been trying to understand the origins of the universe, and how those origins developed into the large structures (i.e. clusters of galaxies) we see today. Over the past several decades, astronomers have developed a standard cosmological model to describe the initial conditions and subsequent evolution of the Universe. To thoroughly test this model would require us to compare the spatial distribution of galaxies that we observe in the real universe with the distribution of galaxies predicted by our model in simulations. However, this poses a challenge because the way in which galaxies cluster is affected both by our cosmological model and by the physics of galaxy formation and evolution, which is not well understood. I will discuss how we can address this challenge, and how studying galaxy clustering can allow us to learn about both the origins of the universe and the physics of galaxy formation. This talk is geared toward the general public.

A Question & Answer session will follow. The Seyfert telescope will open for viewing if weather permits. The talk is handicapped accessible, but the Seyfert is on the second floor and only accessible by stairs.

Gillian Beltz-Mohrmann is in her third year of the Astrophysics Ph.D. program at Vanderbilt University. She earned her bachelor’s degree in Astrophysics from Wellesley College in 2016. As an undergraduate, she worked on several different projects, ranging from exoplanets to variable stars to gravitational waves. At Vanderbilt, her research focuses on large-scale structure formation in the universe. Specifically, her work involves comparing measurements of galaxy clustering from the Sloan Digital Sky Survey to the same measurements from cosmological simulations, in order to improve both our cosmological model and our understanding of galaxy formation.

Open House Days & Telescope Nights

Tickets are available one month before each event. Please note that these events sell out quickly, so plan ahead to avoid disappointment. Visit our Open House Days and Telescope Nights pages for tickets and more information.

There are no Open House or Telescope Night dates in the months of December, January or February, because Dyer Observatory is closed.

Bluebird on the Mountain Concerts

This concert series presented with the world famous Bluebird Cafe is scheduled around glorious sunsets on the portico of the Vanderbilt Dyer Observatory.  Guests are encouraged to bring blankets, lawn chairs, food, and drink and relax on the Observatory’s front lawn to enjoy a fabulous evening of sunset, music, and stars.

Individual concert tickets are available on the first day of the month prior to the show date at noon (i.e. the Oct 6 concert tickets become available Sept 1 at 12pm.) Please note that tickets sell out quickly. A ticket is $135 for a carload with up to 8 guests.

Please go to our Bluebird on the Mountain page for more information.
