Scientists find rare dwarf satellite galaxy candidates in Dark Energy Survey data
"The large dark matter content of Milky Way satellite galaxies makes this a significant result for both astronomy and physics," said Alex Drlica-Wagner of Fermilab and KICP, one of the leaders of the Dark Energy Survey analysis. The Dark Energy Survey is a collaboration of more than 300 scientists from 25 institutions in six countries directed by Josh Frieman of Fermilab and KICP. "The Dark Energy Camera is a perfect instrument for discovering small satellite galaxies," said Keith Bechtol of KICP who helped lead the Dark Energy Survey analysis.
