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.

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.
