Do Galaxy-Free Dark Matter Halos Exist in Universe?

Can universes contain dark matter halos without any galaxies?

A new study by computational astrophysicist Ethan Nadler from the University of California, San Diego, shows that star formation can occur at halos in the solar masses of 10 million people through molecular hydrogen cooling. Nadler calculated the percentage of dark matter halos above the critical mass required for star formation. Image credit: Xiaodian Chen.
