In England it is known as the “Plough,” in Germany the “Great Cart,” and in Malaysia the “Seven Ploughs.” Since humanity first turned its eyes skyward, the seven northern hemisphere stars that compose the “Big Dipper” have been a welcome and familiar introduction to the heavens. “I can recall as a kid making an imaginary […]
Aberration features in directional dark matter detection
May 11, 2012
Nassim Bozorgnia, Graciela B. Gelmini, Paolo Gondolo The motion of the Earth around the Sun causes an annual change in the magnitude and direction of the arrival velocity of dark matter particles on Earth, in a way analogous to aberration of stellar light. In directional detectors, aberration of weakly interacting massive particles (WIMPs) modulates the […]
