These systems are the faintest, most dark matter dominated, and most metal poor galaxies

Here we investigate this issue as motivated by raw merger statistics derived for galaxy-size dark matter halos from ΛCDM simulations. Our analysis shows that a majority (~ 70%) of galaxy halos withM0= 1012Matz= 0 should have accreted at least one object with…
