129, No. 974 (2017 April), pp. 1-5 (5 pages) It is common to attribute a flat rotation curve to our Galaxy. However, in a recent paper, Galazutdinov et al. obtained a Keplerian rotation curve for ...

A team of astronomers at the University of Milano-Bicocca has uncovered a colossal spiral galaxy that existed just 2 billion ...

They discovered that dark matter accounted for roughly 60% of each galaxy's total mass by examining their rotation curves. Blue-shifted gas (moving in the direction of the researchers) and red ...

He found that the rotation curves of galaxies remain flat for millions ... Essentially, it occurs when a massive object, like a galaxy cluster or even a single massive star, bends the path of ...

The galaxy's rotation curve, an important characteristic of spiral galaxies, shows a pattern typical of flat rotation curves seen in mature galaxies. The velocity of the galaxy's rotation ...
