For years, many major simulations handled galaxy gas with a workaround. They stopped it from cooling below about 10,000 ...

New simulations show that early ultraviolet light controlled whether ultra-faint dwarf galaxies could form stars.

The properties of faint dwarf galaxies around the Milky Way can reveal a lot about the conditions of the early universe, the ...

Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new ...

Simulations of faint dwarf galaxies reveal early universe conditions Astronomers have used high-resolution simulations of ultra-faint dwarf galaxies to probe the 'climate' of the early universe. Led ...

Ultra-faint dwarf galaxies orbiting the Milky Way are cosmic fossils. New simulations reveal how these tiny systems reflect ...

Understanding the universe as a whole requires simulations on cosmic scales. An international team of astrophysicists, with a ...
