CWRU Virgo Cluster Survey now available online

Date posted: December 8th, 2016

This fall marks the full public release of CWRU Astronomy’s Burrell Schmidt Deep Virgo Survey. Over the course of seven observing seasons from 2004 through 2011, CWRU astronomer Chris Mihos and collaborators used the Burrell Schmidt telescope to conduct deep wide-field imaging of the nearby Virgo Cluster of galaxies. …Read more.

Every year CWRU Astronomy holds a Halloween pumpkin carving event for faculty, staff, and students. This year added an extra treat — a campus-wide power outage in the middle of the carving! …Read more.

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.

Alumni Update: Dr Jessica Gaskin

Date posted: May 19th, 2016

NASA scientist and CWRU alumna Dr Jessica Gaskin recently won NASA’s Early Career Achievement Medal for her work in developing X-ray telescopes to study the Sun, stars, and galaxies. But back when she was a graduate student in the CWRU Astronomy Department, she learned a valuable lesson from her mentor, Professor Earle Luck: you gotta break things to make progress in science. …Read more.

Galaxies and Alternative Gravity

Date posted: February 17th, 2016

Interested in galaxy dynamics and prospects for alternative gravity models? In a recent TEDxCLE talk, CWRU Astronomy’s Stacy McGaugh discusses how the kinematics of galaxies presents new challenges to models of cosmology and galaxy formation, and how alternative gravity models might be a viable explanation for how galaxies behave. …Read more.

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.
