A Dizzying Diversity of Dwarf Galaxies
Today’s paper explains why the rotation curves of dwarf galaxies continue to baffle astronomers.
Not Far in the Dark
To confirm whether some galaxies have suspiciously low amounts of dark matter, we need to be sure how far away they are.
The Nobel Prize for the Foundations of Modern Cosmology
Half of the 2019 Nobel Prize in Physics was awarded to James Peebles for his work in physical cosmology. Come read about some of his contributions that led to this recognition!
Dwarf Galaxies without Dark Matter
Today’s paper looks at observations of 19 low mass galaxies which appear to contain no dark matter, potentially challenging our overall understanding of galaxy formation.
Seeing Double: Binary stars in dwarf galaxies
Two (stars) aren’t always better than one, especially when you’re trying to track down dark matter in tiny galaxies.
The Milky Way’s Ghostly Neighbor
The unique nature of the newly discovered dwarf galaxy Ant 2 may have exciting implications for our understanding of dark matter and galaxy formation.
