Supernovae, neutron star collisions and active galactic nuclei are among the most energetic phenomena in the known universe. These violent explosions produce high-energy gamma rays and cosmic rays, ...

Today, scientists operating the High Altitude Water Cherenkov (HAWC) Gamma-ray Observatory released a new survey of the sky made from the highest energy gamma rays ever observed. The new sky map, ...

In a remote section of desert in southern Mexico, on the slopes of the dormant Sierra Negra volcano, lies a collection of 300 steel tanks, each the size of a small house. Together, they take up an ...

Stefan Westerhoff introduces a gamma ray detector used to study explosions in the sky. Stefan Westerhoff, Professor, Department of Physics, UW-Madison, introduces us to the next generation gamma ray ...

Michigan Tech team and others use a high-altitude observatory in Mexico to better understand where gamma rays come from. A mountaintop observatory about four hours east of Mexico City, built and ...

A strange star system in our own galaxy is producing some of the most powerful gamma rays ever seen. Messengers from this microquasar may offer a glimpse into bizarre objects at the centers of distant ...

The High-Altitude Water Cherenkov Gamma-Ray Observatory (HAWC) collaboration has detected highly energetic light coming from a microquasar -- a black hole that gobbles up stuff from a companion star ...

A long-time question in astrophysics appears to finally be answered, thanks to a collection of large, high-tech water tanks on a mountainside in Mexico. The High-Altitude Water Cherenkov (HAWC) data ...
