Astrophysics & Cosmology
For the 41st annual Particle Physics & Astrophysics Department’s SLAC Summer Institute (SSI), organizers introduced a successful new feature.
In addition to hearing the traditional program of high-level physics lectures and enjoying the social events, the particle physics graduate students formed teams to work on one of four mini-projects during the two-week institute held July 8–19. They reported their findings on the penultimate day.
Now that it looks like the hunt for the Higgs boson is over, particles of dark matter are at the top of the physics "Most Wanted" list. Dozens of experiments have been searching for them, but often come up with contradictory results.
A record-setting blast of gamma rays from a dying star in a distant galaxy has wowed astronomers around the world. The eruption, which is classified as a gamma-ray burst, or GRB, and designated GRB 130427A, produced light with the highest energy ever measured from such an event.
