Testing DAMA

An Italian experiment has a 20-year signal of what could be dark matter—and scientists are embarking on their most promising efforts yet to confirm or refute its results. For more than two decades, DAMA has observed a regularly changing signal that its operators think comes from our planet’s movements through the “halo” of dark matter suffusing the Milky Way galaxy.

From Popular Science, July 29, 2019: “Death by Dark Matter” is not the name of your new favorite metal band; it’s the literal title of a new study by a trio of American of physicists. Fermilab science Dan Hooper is quoted in this article on their paper, which explores what the hypothetical consequences might be on the human population if a certain candidate of dark matter turned out to be true.

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.
