The distribution of normal matter precisely determines gravitational acceleration in all common types of galaxies, a team led by Case Western Reserve University researchers reports. The team has shown ...

Researchers have found a significant new relationship in spiral and irregular galaxies: the acceleration observed in rotation curves tightly correlates with the gravitational acceleration expected ...

Electrons trapped in the Van Allen radiation belt surrounding the Earth can have several megaelectronvolts of energy. Scientists believe that either these charged particles originate from the outer ...

The team has shown this radial acceleration relation exists in nearby high-mass elliptical and low-mass spheroidal galaxies, building on last year's discovery of this relation in spiral and irregular ...
