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. Come inside and learn more about our on-going research, our faculty, staff, and students, and all the new things happening in CWRU Astronomy.

You can also read the latest edition of our annual CWRU Astronomy newsletter.



New Radial Acceleration Law Discovered for Rotating Galaxies

Date posted: September 22nd, 2016

A new radial acceleration relation found among spiral and irregular galaxies challenges current understanding – and possibly existence – of dark matter.
In the late 1970s, astronomers Vera Rubin and Albert Bosma independently found that spiral galaxies rotate at a nearly constant speed: the velocity of stars and gas inside a galaxy does not decrease with radius, as one would expect from Newton’s laws and the distribution of visible matter, but remains approximately constant. …Read more.


CWRU Astronomy Newsletter – 2016 Edition

Date posted: September 8th, 2016

With the new fall semester kicking off, we’ve just published the latest CWRU Astronomy newsletter. It features a Hubble Space Telescope study of the nearby spiral galaxy M101 by Chris Mihos and collaborators, a variety of new research databases created by CWRU astronomers, a feature of our historic 9.5″ Warner and Swasey refractor, and more. …Read more.


SPARC Galaxy Database

Date posted: August 26th, 2016

The new Spitzer Photometry and Accurate Rotation Curves (SPARC) database is publicly available online. Created by team leaders Federico Lelli and Stacy McGaugh (CWRU Astronomy) and Jim Schombert (UOregon Physics), SPARC is a sample of 175 disk galaxies covering a broad range of morphologies (S0 to Irr), luminosities (107 to 1012 Lsun), and sizes (0.3 to 15 kpc). …Read more.


Shaking up Dark Matter at the World Science Festival

Date posted: June 3rd, 2016

For years, the reigning model for cosmology argues that the universe is filled with unseen dark matter, believed to comprise the bulk of the mass in the universe. However, despite painstaking searches, scientists have yet to detect particles which would make up this dark matter. …Read more.
