Today’s paper suggests that globular clusters might come from a newly-discovered class of low-mass galaxies called “Little Blue Dots.” And even if you don’t care about globular clusters, you should read this post anyway to learn about some weird names for different types of galaxies.
The universe is filled with tiny, faint dwarf galaxies. The authors of this paper are on the hunt for them.
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.
Does the shape of the dark matter distribution in the Milky Way’s satellite galaxies depend on the direction from which they are observed?
Hidden forces may leave their fingerprints in the smallest galaxies.
