ANIMATION “Sterile neutrinos” are theoretically predicted new particles that offer an intriguing possibility in the quest for understanding the dark matter in our universe. Unlike the known “active” neutrinos in the Standard Model (SM) of particle physics, these sterile neutrinos do not interact with normal matter as they move through space, making them very difficult to […]

ANIMATION UC Riverside-led study finds extreme tidal mass loss in dwarf galaxies formed in a simulation. A team led by astronomers at the University of California, Riverside, has found that some dwarf galaxies may today appear to be dark-matter free even though they formed as galaxies dominated by dark matter […]

This work was based on measurements data of the helium spectrum with kinetic energies from 70 GeV to 80 TeV (17.5 GeV/n […]

This animation shows the distribution of the dark matter, obtained from a numerical simulation, when the universe was about 3 billion years old.

The […]

The map reveals a bright patch, a wake of stars, beneath the Milky Way’s halo. In the bottom right, the Large Magellanic Cloud continues its orbit (Image credit: NASA/ESA/JPL-Caltech/Conroy et. al) The wake was revealed by a new map of the outermost region of our galaxy. A mysterious wake of […]

Hubble Space Telescope observation of galaxy cluster Abell 3827. Credit: ESA/Hubble & NASA, R. Massey This detailed image features Abell 3827, a galaxy cluster that offers a wealth of exciting possibilities for study. It was observed by Hubble in order to study dark matter, which is one of the greatest puzzles […]

This exoplanet, a gas giant called GJ 504b, is about 57 light-years away from Earth. Exoplanets like this may help researchers find and measure dark matter.

In the recent past, space missions dedicated to the study of astrophysical signals in the high-energy spectrum revealed a series of enigmatic excesses not predicted by the theoretical models. In order to find an explanation for these anomalies, many solutions have been proposed. The most exciting hypothesis invokes the contribution […]

ANIMATION Scientists of the PRISMA+ Cluster of Excellence analyze data from the gravitational wave observatory NANOGrav. The NANOGrav Collaboration recently captured the first signs of very low-frequency gravitational waves. Prof. Pedro Schwaller and Wolfram Ratzinger analyzed the data and, in particular, considered the possibility of whether this may point towards new […]
