Rolf Landauer showed that "information is physical" with every bit equivalent to a small amount of energy proportional to ...

Dark matter, though invisible, weaves a vast cosmic web that binds galaxies together. For the first time, astronomers have ...

Scientists used infrared spectrographs to detect dark matter decay. No signals appeared, but anomalies suggest more ...

"It was actually a total surprise to find the satellites in that configuration and we still don’t fully understand why they ...

Abstract: A method of deriving and using merging history trees of dark matter galaxy haloes directly from pure gravity N-body simulations ... are shown. As an example of a galaxy formation model, ...

Most of them are solitary. In this new work, we show how to effectively double the number of pulsars we can use to constrain dark matter in the galaxy by rigorously using solitary pulsars to ...

Galaxies don't float around at random. They line up along strands of cosmic filaments, sometimes stretching millions of light ...

Is it possible that dark matter, which makes up 85% of the cosmic matter budget, is simply a collection of primordial black ...

XRISM has uncovered how galaxy clusters evolve—violent mergers create turbulence, preventing hot gas from cooling. This ...

In this scenario, galaxies are assembled within a structure of dark matter, the gravity of which ... This is known as hierarchical formation. The satellite galaxies that we see today are the ...

Scientists are learning about star formation by studying a neighbor of the Milky Way ... Cutting-edge spectrographs give most stringent limits for dark matter lifetime.
