The Nanohertz Gravitational-Wave Detection Explained
• Physics 16, 116
Jorge Cham, aka PHD Comics, illustrates how researchers have turned our Galaxy into a giant antenna for catching gravitational waves, spotting for the first time a background hum of such waves.
Gravitational-wave signals from black hole mergers could reveal the presence of “gravitational atoms”—black holes surrounded by clouds of axions or other light bosons. Read More »
Using an old film as input, researchers demonstrate an algorithm that rapidly determines the positions of thousands of particles whose light-scattering produces an image or other desired output. Read More »
A new survey shows that affinity groups provide crucial support to women and LGBTQ+ physics PhD students—groups that continue to experience harassment and hostility. Read More »
