Separating the cosmic wheat from the chaff: Cosmological parameter estimation with the 21-cm line
Today’s authors might just be able to resolve some major cosmological debates with a new parameter estimation method!

When it comes to future surveys in precision cosmology, even the smallest uncertainties cannot be so easily neglected.
So that’s what happens when astronomers account for magnetic fields!
In the study of structure formation in the universe, the ‘missing satellite galaxies’ problem is said to be almost solved. Is today’s paper the final nail in the coffin?
There’s lots of them out there. The answer to some of the mysteries of the universe could be hidden in their numbers.
Hidden forces may leave their fingerprints in the smallest galaxies.
