The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

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

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

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

A unified theory – that explains the interactions in the standard model of particle physics from one common origin – has been ...

Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle proposed for decades to explain puzzling neutrino behavior. Their high-precision ...

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up of my favourite research of 2025 I have chosen five stories in which ...

New results from the MicroBooNE experiment rule out the existence of a sterile neutrino, reshaping how scientists think about ...

"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting ...

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work ...

Drexel’s Department of Physics is home to faculty who are leaders in the field of particle physics. Our research spans neutrino properties, neutrino astronomy, and the search for dark matter, and our ...

Particle physics is a branch of physics that studies the elementary constituents of matter and radiation, and the interactions between them. It is also called "high energy physics", because many ...
