Gamma-ray outburst detected from the radio source 3C 216
Using NASA's Fermi space telescope, Italian astronomers have observed a radio source known as 3C 216. As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is reported ...
The LZ experiment's first science run sets new constraints on dark matter interactions
The LUX ZEPLIN (LZ) Dark Matter experiment is a large research effort involving over 200 scientists and engineers at 40 institutions worldwide. Its key objective is to search for weakly interacting massive particles (WIMPs) ...
A CubeSat mission will detect X-rays from GRBs and black-hole mergers
The long-awaited detection of gravitational waves has opened up a whole new world of astronomy. One of the key efforts is now to tie signals across multiple domains—for example, a gravitational wave and the associated electromagnetic ...
