Research news on Baryonic dark matter
Baryonic dark matter as a research area investigates the fraction of non-luminous matter composed of standard-model baryons—primarily protons, neutrons, and their bound states—that contributes to galactic and cosmological mass budgets. It focuses on identifying and constraining compact and diffuse baryonic components such as MACHOs, cold gas, dust, and low-luminosity stellar remnants using techniques including microlensing surveys, 21-cm observations, and cosmic microwave background baryon-density constraints. The field assesses how much of the observed gravitational effects can be attributed to baryons versus non-baryonic dark matter, refining models of structure formation, baryon cycling, and the baryon census in the universe.
Dark dwarfs lurking at the center of our galaxy might hint at the nature of dark matter
Celestial objects known as dark dwarfs may be hiding at the center of our galaxy and could offer key clues to uncover the nature of one of the most mysterious and fundamental phenomena in contemporary cosmology: dark matter.

Observing dark matter at cosmic dawn
After almost a century of speculation, proposals and searches for dark matter, physicists now know that it currently comprises about 27% of the universe's mass-energy, with an abundance over five times that of ordinary matter ...
Dark matter could have slight interaction with regular matter, study suggests
The reason we call dark matter dark isn't that it's some shadowy material. It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. ...

Heaviest antimatter observation yet will fine-tune numbers for dark matter search
In experiments at the Brookhaven National Lab in the US, an international team of physicists has detected the heaviest "anti-nuclei" ever seen. The tiny, short-lived objects are composed of exotic antimatter particles.
