Astronomy: A rotating system of satellite galaxies raises questions

Academics / Astronomy : EurekAlert: Space

(University of Basel) Astronomers have examined the distribution and movement of dwarf galaxies in the constellation Centaurus, but their observations do not fit with the standard model of cosmology that assumes the existence of dar...

Cosmological Models Proven Correct by Dark Energy Survey

Technology / Hardware : Extremetech

While we cannot directly observe dark matter and dark energy, we know these are the driving force behind the universe's expansion. To test the predictions made by the standard model of cosmology, scientists needed to observe a huge ...

Strongly baryon-dominated disk galaxies at the peak of galaxy formation ten billion years ago

Academics : Nature

In the cold dark matter cosmology, the baryonic components of galaxies—stars and gas—are thought to be mixed with and embedded in non-baryonic and non-relativistic dark matter, which dominates the total mass of the galaxy and its da...

Galaxy Rotation Negates Dark Matter --"If There's a Single Observation That We Might Have Something Essentially Wrong, This is It"

Academics / Astronomy : The Daily Galaxy

"The standard model of cosmology is remarkably successful at explaining just about everything we observe in the universe," said Arthur Kosowsky, professor of physics and astronomy at the University of Pittsburgh, was not involved bu...

Dark Matter Particles That Make Up All Galaxy Halos --"Are Like a Swarm of Bees, Moving Chaotically"

Academics / Astronomy : The Daily Galaxy

Dark matter extends far beyond the reach of the furthest stars in the galaxy, forming what scientists call a dark matter halo. While stars within the galaxy all rotate in a neat, organized disk, these dark matter particles are like....
