Discoveries using the telescopes on Mauna Kea

Thanks, HOTPE. Similar projects have been going on elsewhere in the world and have proved very successful, so hope that's the same here. In the meantime:

"Discovery in the early universe poses black hole growth puzzle"

This involves the Keck Observatory on MK. Quasars are active galaxies, meaning that matter is falling into the central supermassive black holes which results in extremely energetic outflows which brighten the galaxy considerably and make them easily visible to telescopes even though they are very distant. However, the mass of the black holes (typically the mass of a billion suns!) can only be easily explained by matter falling into them over at least 100 million years, but a few seem to have reached their size and mass in only 100,000 years.
