Algorithm simulates the intergalactic medium of the universe

The Instituto de Astrofísica de Canarias (IAC) led the development of a new numerical procedure to reproduce the intergalactic medium obtained from a cosmological simulation of 100,000 hours of computation using big data ...

New light on baryonic matter and gravity on cosmic scales

Scientists estimate that dark matter and dark energy together are some 95% of the gravitational material in the universe while the remaining 5% is baryonic matter, which is the "normal" matter composing stars, planets and ...

Missing baryons found in far-out reaches of galactic halos

Researchers have channeled the universe's earliest light—a relic of the universe's formation known as the cosmic microwave background (CMB)—to solve a missing-matter mystery and learn new things about galaxy formation. ...

On the hunt for primordial black holes

The theory that dark matter could be made of primordial black holes a fraction of a millimeter in size has been ruled out by a team of researchers led by the Kavli Institute for the Physics and Mathematics of the Universe ...

How we discovered a glowing galactic ghoul

It's a classic Halloween tale. A group of ghost hunters visit a grand old house that is rumored to be haunted. But after thoroughly exploring, they leave disappointed: there are no ghosts to be seen. Only later, when looking ...
