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.

 

A plot of the number of galaxies as a function of redshift along a particular direction in the sky. Spikes in the counts correspond to newly identified protoclusters of galaxies. In this single field (CANDELS GOODS-S), the CWRU team identified 9
protoclusters as galaxy overdensities along the line of sight. At a redshift of 3, light has travelled more than 11 billion years to reach Earth.

CWRU Astronomers Find Young Galaxy Protoclusters in the Early Universe

Date posted: December 18th, 2015

A team of CWRU astronomers has recently identified 43 new protoclusters of galaxies, seen as they were 12 billion years in the past, when the Universe was only a few billion years old. …Read more.

A Stellar Contribution

Date posted: November 30th, 2015

We are always grateful for the strong support we receive from our alumni and friends. CWRU alumnus Walter Bonsack (’54) got his start in astronomy as an undergraduate, using the Burrell Schmidt (located at the time in East Cleveland) to study the chemical composition of early type stars. …Read more.
