Fat or flat: getting galaxies into shape
Perth, Australia (SPX) Mar 04, 2014
Australian astronomers have discovered what makes some spiral galaxies fat and bulging while others are flat discs - and it's all about how fast they spin. The research, led by the International Centre for Radio Astronomy Research (ICRAR) in Perth, found that fast-rotating spiral galaxies are flat and thin while equally sized galaxies that rotate slowly are fatter. The study was published in the prestigious Astrophysical Journal and was part of "The Evolving Universe" research theme of the ARC Cen ... read more
