Unlocking the secrets to dark matter

Post by Dragon on Wed Apr 18, 2018 4:12 pm

University of Miami astrophysicist Nico Cappelluti studies the sky. An assistant professor in the Physics Department, Cappelluti is intrigued by the cosmic phenomena of super massive black holes, the nature of dark matter, and active galactic nuclei, which is the very bright light source found at the center of many galaxies.

Recently, Cappelluti published findings that could give insight on a subject scientists and astrophysicists have been investigating for decades: What is dark matter and where does it come from?

According to Esra Bulbul, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics and co-author in Cappelluti's study, about 95 percent of the mass in the universe is made up of material that is unknown and invisible to scientists, that is dark matter.

This artist's impression shows the Milky Way galaxy. The blue halo of material surrounding the galaxy indicates the expected distribution of the mysterious dark matter, which was first introduced by astronomers to explain the rotation properties of the galaxy and is now also an essential ingredient in current theories of the formation and evolution of galaxies.

New measurements show that the amount of dark matter in a large region around the Sun is far smaller than predicted and have indicated that there is no significant dark matter at all in our neighbourhood.

Simulation of the evolution of the theorized dark matter halo around the Milky Way galaxy from the galaxy's formation to today.
