A perplexing "break" in a stream of stars around the Milky Way could be the result of dark matter — that is, if the mysterious cosmic stuff interacts with itself. The feature in question is in ...

"For the first time, we could trace the boundary between the gas residing in galaxies and the material contained within the ...

known as Lambda Cold Dark Matter (λ-CDM). This model has been the backbone of cosmology for decades. It posits that the gravitational pull of dark matter allowed early stars and galaxies to ...

and exploring the implications of various tensions and anomalies that challenge the standard cosmological model known as ΛCDM (Lambda Cold Dark Matter). One of the most pressing issues in ...

the Lambda Cold Dark Matter (LCDM) model. “When comparing to the novel high-definition image of the cosmic web, we find substantial agreement between current theory and observations," Tornotti said.

Abstract: We use the Om statistic and the genetic algorithms (GAs) in order to derive a null test on the spatially flat cosmological constant model Lambda cold dark matter (ΛCDM). This is done in two ...

Mathematical equations have shaped our understanding of the universe, and these nine have played a key role in changing the world.

Central to the widely accepted Lambda Cold Dark Matter (LCDM) model of cosmology, dark matter plays a crucial role in our understanding of the cosmos. Yet, its true nature remains elusive. One of the ...

Astronomers have photographed a unique thread in the cosmic web that connects two galaxies that existed when the Universe was ...

Largest Discovery: Quipu is the biggest structure found in the Universe. Content: Along with four other superstructures, it holds 45% of galaxy clusters, 30% of galaxies, 25% of matter, and occupies ...
