A massive clump of dark matter in the Perseus galaxy cluster is linked to its core by a bridge of dark matter, evidence of a ...

The infant universe's population of huge black holes could owe itself to ultralight dark matter, scientists say.

Mysterious dark matter makes up 85 percent of matter in the universe, and of the remaining 15 percent, scientists couldn’t ...

A groundbreaking study,published in March 2025 on the preprint server arXiv, reveals that ultralight dark matter might have ...

Astronomers have long been puzzled by two strange phenomena at the heart of our galaxy. First, the gas in the central ...

The researchers' numerical simulations suggest that the newly detected dark matter substructure collided with the Perseus cluster some five billion years ago. "It took courage to challenge the ...

An international team of astronomers has solved one of the longstanding cosmic mysteries by uncovering direct evidence of a ...

A new analysis of the sky has finally confirmed where the missing half of the Universe's visible matter has been hiding.

The CMZ spans almost 700 light years and contains some of the most dense molecular gas in the galaxy. Over the years, ...

An important next step will be to see how well the idea holds up in more realistic simulations of the early universe. Of note, other researchers have proposed dark matter as part of black hole ...

Using detailed simulations, we found that this simple process, dark matter particles annihilating into electrons and positrons, can naturally explain the ionisation rates observed in the CMZ.
