Welcome to CWRU Astronomy
CWRU Astronomy is a community of active researchers and educators, with research strengths in the fields of galaxy formation and evolution, stellar chemical abundances, and telescope instrumentation and design.
We offer graduate and undergraduate degree programs, and host a series of public talks for the general public. Learn more about our ongoing research, our faculty, staff, and students, and all the new things happening in CWRU Astronomy.
The CWRU Department of Astronomy stands in solidarity with our Black colleagues and fellow citizens across the United States in expressing what should be a clear moral absolute: that people of color should enjoy the same freedoms as other Americans to life, liberty, and the pursuit of happiness. We condemn the de facto system of racial oppression that leads to pervasive police brutality up to and including the extrajudicial murders of Black Americans like George Floyd and far too many others.
This June, CWRU Astro graduate student Pengfei Li successfully defended his doctoral thesis "The Dark Matter Problem in Rotationally Supported Galaxies", under the supervision of Professor Stacy McGaugh. Using the high quality SPARC database of disk galaxy rotation curves, Pengfei fit rotation curves to a wide variety of dark matter halo models, providing tight constraints on the properties of the galaxies' dark matter halos. With the very large SPARC sample of 175 galaxies, Pengfei demonstrated the need for galaxies to be fit with "cored" dark matter halos rather than the cuspy halos predicted by dark matter only simulations. The cored...
This spring, while visiting the Department of Astronomy at Columbia University, CWRU astronomy senior Chris Carr had a chance to meet noted astrophysicist and science educator Neil deGrasse Tyson.
On April 1 2019, CWRU Astronomy found itself in the middle of magical turmoil, as Harry Potter and his friends battled the forces of Lord Voldemort to save the Hubble Space Telescope.
