One in five galaxies in the early universe could still be hidden behind cosmic dust

Astronomers at the University of Copenhagen’s Cosmic Dawn Center have discovered two previously invisible galaxies billions of light-years away. Their discovery suggests that up to one in five such distant galaxies…

Ultracoherent mechanical devices

Similarly, a phononic crystal is a fabricated object with a repeating pattern that gives it a particularly useful property – a bandgap that forbids the propagation of motion at certain frequencies. This allows us to…
