A study led by UC Riverside physicist Hai-Bo Yu suggests that a new type of dark matter could explain three astrophysical puzzles across vastly different environments. Published in Physical Review Letters, the study proposes that dense clumps of self-interacting dark...
A key factor for the performance of sensors is the speed at which the system returns to its initial state after a disturbance or measurement, similar to the taring of a balance. In the quantum sensor under investigation, this corresponds to the transition of electrons...
At this point in NASA’s human spaceflight story, researchers have a substantial amount of material—documents, artifacts and images—with which to tell the stories of past flights to space. But with NASA’s Artemis II mission around the moon now in the books,...
The center of our galaxy is an extreme place. Surrounding the supermassive black hole Sagittarius A*, stars are packed densely into a region where gravity, radiation, and dark matter all interact in complex ways. It is a natural laboratory for testing some of the...
A new study by scientists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) shows that when a pressure disturbance moves across an ultrasoft elastic material, such as a gel or a biological tissue, it generates a V-shaped wake...
