dark matter

As she grew up in the small town of San Pellegrino in the Italian Alps, three things conspired to make Maria Elena Monzani a physicist: a fascination for outer space, a Nobel Prize and a nuclear disaster. Now she prepares an international team to search for clues to one of the biggest scientific mysteries.

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.

From Physics Today, June 1, 2019: Fermilab scientist Aaron Chou is an author on this article on how microwave cavity experiments make a quantum leap in the search for the dark matter of the universe. The experimental hunt for a dark matter candidate called the axion has been going on for decades, and today, a number of experiments are putting the squeeze on this hypothesized particle.

Scientists are redoubling their efforts to find dark matter by designing new and nimble experiments that can look for dark matter in previously unexplored ranges of particle mass and energy, using previously untested methods. Dark matter could be much lower in mass and slighter in energy than previously thought.

Rakshya Khatiwada is an experimental astrophysicist at Fermilab working on dark matter searches and quantum science. When she’s not developing the newest detectors to look for dark matter, Khatiwada makes a point to engage with the next generation of scientists through informal lunches, talks and webinars.

From EarthSky, May 2, 2019: University of Chicago physicists and a former Fermilab scientist have laid out an innovative method – using the Higgs boson – for stalking dark matter. He said the Higgs might actually be “a portal to the dark world.”
