Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics.

You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

The handheld particle detector CosmicWatch is roughly the size of a box of animal crackers. Every time a muon passes through ...

Spencer Axani, assistant professor in the Department of Physics and Astronomy, is the inventor of CosmicWatch, a portable, ...

A recent study offers proof of feasibility for using cosmic radiation detectors to discover underground spaces. The detectors identify muons—particles created when cosmic radiation collides with Earth ...

Muons continually bombard the ground at a known rate and angular distribution. As muons lose energy when passing through matter, their flux is attenuated depending on the integrated density along ...

Muon radiography and tomography are innovative non‐destructive imaging techniques that employ cosmic-ray muons to probe the internal structures of large objects, from ancient monuments to active ...
