The sky with very-high-energy gamma rays: HAWC’s first year of observations

HAWC, a very-high-energy observatory, has today revealed the results of its first year of operation. The sky viewed with gamma rays shows some of the most explosive events in our galaxy, the Milky Way, and beyond. With HAWC, scientists observe the aftermath of the death of massive stars, glowing clouds of electrons around rapidly spinning neutron stars and supermassive black holes in other galaxies that are devouring matter and spitting out powerful jets of particles.

Ignacio Taboada, physics faculty at Georgia Tech is HAWC’s science coordinator.

The First Gravitational Waves have been Detected!

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos.

The gravitational waves were detected on September 14, 2015 at 5:51 a.m. Eastern Daylight Time (9:51 UTC) by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. The LIGO Observatories are funded by the National Science Foundation (NSF), and were conceived, built, and are operated by Caltech and MIT. The discovery, accepted for publication in the journal Physical Review Letters, was made by the LIGO Scientific Collaboration (which includes the GEO Collaboration and the Australian Consortium for Interferometric Gravitational Astronomy) and the Virgo Collaboration using data from the two LIGO detectors.
