Imagine a particle. What comes to mind? If you aren’t a theoretical particle physicist, chances are you picture a tiny ball, bobbing in space. But that’s not quite correct. One way to prove it: Try to imagine that tiny ball as a particle with no mass. If a particle has no mass, how can it exist?

In the world of particle physics, scientists work with tiny, invisible particles, tracking their collisions and interactions with one another. But what if you could render them as music? What would these songs of the subatomic sound like? Adam Nadel, Fermilab’s 2018 artist-in-residence, worked with scientists at Fermilab and set out to do just that. Read on to hear his music.

As president, Frieman will oversee the affairs and business of the esteemed organization. More than 1,000 scientists every year visit the center to explore new research in physics, astrophysics and related fields.

Right now could be considered one of the best — and most uncertain — times in theoretical physics. That’s what Symmetry heard in interviews with 10 junior faculty in the field. They talk about what keeps them up at night, their favorite places to think and how they explain their jobs to nonscientists.

Major deliveries in June set the stage for the next phase of work on LUX-ZEPLIN project, led by Lawrence Berkeley National Laboratory. A Fermilab group is responsible for implementing key parts of the critical systems that handle the xenon in the detector.

It took three sky surveys to prepare for a new project that will create the largest 3-D map of the universe’s galaxies and glean new insights about the universe’s accelerating expansion. This Dark Energy Spectroscopic Instrument project will explore this expansion, driven by a mysterious property known as dark energy, in great detail. The surveys, which wrapped up in March, have amassed images of more than 1 billion galaxies and are essential in selecting celestial objects to target with DESI, now under construction in Arizona.

Postdoc Guillermo Fernandez Moroni is recognized for his outstanding work on the SENSEI experiment at Fermilab. Dark matter experiments are quite sensitive to unwanted background noise, and Moroni found a way to limit this noise for SENSEI, increasing the sensitivity of the experiment by a factor of a thousand, making it the most sensitive of its kind in the world.

Dhuley and his team at the Illinois Accelerator Research Center have received the William E. Gifford Award for their work on cryocooling acceleration cavities. Their research on cryocooler-based systems is paving the way for compact particle accelerators that can operate at ultracold temperatures without complicated cooling infrastructure.

Particle accelerators are some of the most complicated machines in science. In today’s more autonomous era of self-driving cars and vacuuming robots, efforts are going strong to automate different aspects of the operation of accelerators, and the next generation of particle accelerators promises to be more automated than ever. Scientists are working on ways to run them with a diminishing amount of direction from humans.

When teaching a physics lab how to be more LGBTQ+ inclusive, workshop presenters decided to lead with the science.
