Unexpected Rotational Motion Detected in Ultra-Diffuse Galaxies of Hydra Cluster
Astronomers studying ultra-diffuse galaxies (UDGs) in the Hydra cluster have observed unexpected rotational movement in nearly half of the 30 galaxies examined. Spectroscopic data from the LEWIS programme, using the MUSE instrument on the Very Large Telescope, suggests that gravitational interactions with larger galaxies may influence their formati...

New Study Reveals How Pulsars Help Measure Dark Matter in the Milky Way
A breakthrough study has used pulsar acceleration data to measure dark matter density in the Milky Way. Previously, binary pulsars were the primary source of data, but now solitary pulsars have been included, doubling the dataset. The research also provides evidence of the Milky Way’s "wobble" due to interactions with dwarf galaxies. By mapping t...

Frontier Supercomputer Simulates Universe with Unmatched Complexity
The Frontier supercomputer at Oak Ridge National Laboratory has conducted the most detailed universe simulation to date. Using the Hardware/Hybrid Accelerated Cosmology Code (HACC) under the U.S. Department of Energy’s Exascale Computing Project, the model incorporates dark matter, gas, and plasma interactions. With speeds reaching 1.4 exaFLOPS, ...

Euclid Space Telescope Discovers Rare Einstein Ring, Revealing Dark Matter Secrets
The Euclid space telescope has detected a rare Einstein ring around galaxy NGC 6505, located approximately 590 million light-years from Earth. This phenomenon, resulting from gravitational lensing, allows scientists to study the distribution of dark matter within the lensing galaxy. The discovery aligns with Euclid's mission to map cosmic structure...

Scientists Discover Hidden Clues to the Dark Universe in 3D Galaxy Maps
A breakthrough study has revealed new insights into the "dark universe," which consists of dark matter and dark energy. By using a novel technique called field-level inference (FLI), scientists have discovered previously hidden details in 3D galaxy maps. This method preserves the three-dimensional nature of the data, unlike traditional compression ...

Dark Matter Mass Limits Linked to Higgs Boson Interactions
Efforts to unravel dark matter's mysteries have revealed a potential mass limitation due to its interaction with the Higgs boson. A new study suggests that dark matter particles exceeding a few thousand giga-electron volts (GeV) could disrupt the Higgs boson, altering fundamental physical laws. This finding challenges the Standard Model and prompts...

Invisible Boson Stars Could Hold the Key to Dark Matter's Mysteries
Boson stars, invisible celestial objects theorised to form from axions, are now at the centre of dark matter research. Axions, light and wave-like bosons, may cluster under gravity, forming these mysterious entities. Unlike normal stars, boson stars neither emit light nor interact with regular matter in observable ways. With sizes ranging from smal...

Heavy Dark Matter Could Break the Standard Model, New Research Shows
New research warns that heavy dark matter particles could interfere with the Higgs boson, leading to instability in the Standard Model of particle physics. If confirmed, this could reshape how dark matter is studied, suggesting lighter particles or new interaction mechanisms. Scientists may need to adjust experiments to focus on low-mass candidates...

Researchers Study Dark Matter Conversion Signals in Earth's Ionosphere
A study explored the potential of Earth's ionosphere as a medium to detect dark matter particles, specifically axions and dark photons. Researchers propose that these particles could convert into low-frequency radio waves within the ionosphere's plasma, creating detectable signals. By utilizing small, cost-effective dipole antennas, scientists aim ...
