A simple calculation of the radial acceleration from the average flow rates in the microchannel overestimates the acceleration that we observed experimentally, mainly because of the damping of the ...
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 ...
One point of evidence in support of dark matter is the way in which the speed of stars, gas and dust in a galaxy varies with their distance from the center of the galaxy, known as the galactic ...
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 ...
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 ...
Accelerated electrons whizz about in the Van Allen belts. (Courtesy: Geoff Reeves, Los Alamos National Laboratory) The debate surrounding how ultra-relativistic electrons trapped in the Earth’s Van ...
Relativistic electrons in the outer Van Allen belt wreak havoc with satellites in geosynchronous orbit, but how they reach such high energies has been unclear. New data identify gyro-resonant ...
