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 […]

ANIMATION Factoring in Gravitomagnetism Could Do Away With Dark Matter Models of galactic rotation curves built of a general relativistic framework could use gravitomagnetism to explain the effects of dark matter. Observations of galactic rotation curves give one of the strongest lines of evidence pointing towards the existence of dark […]

ANIMATION What is the origin of black holes and how is that question connected with another mystery, the nature of dark matter? Dark matter comprises the majority of matter in the Universe, but its nature remains unknown. Multiple gravitational wave detections of merging black holes have been identified within the […]

Simulation of a collision in the Large Hadron Collider, producing the Higgs boson. © 1997-2021 CERN (CC-BY-SA-4.0) Credit: University of Granada An international team of scientists proposes a new heavy particle with properties similar to those of the Higgs boson. Unlike the Higgs boson, discovered at CERN’s Large Hadron Collider in […]

On the left is a simulated image in which intracluster light is visible as a diffuse haze between discrete peaks of brightness — the galaxies. In observations, as seen in the right, this intracluster light component is largely drowned in noise. Credit: Left image: Jesse Golden-Marx; simulation by The IllustrisTNG. […]

Axions are a hypothetical particle that might explain the existence of dark matter. But it might occasionally interact with normal matter, especially in the cores of stars. A team of physicists have searched for evidence of axions in Betelgeuse and come up with nothing. It doesn’t mean that the axion […]
