The La Silla QUEST Kuiper belt Survey

Megan Schwamb

Megan Schwamb & David Rabinowitz used the La Silla QUEST Survey to search for Pluto-sized objects in the outer solar system. 

The La Silla QUEST Kuiper belt Survey is searching for the largest and brightest planetesimals in the outer solar system in the Southern Hemisphere.  Using the ESO 1.0-m Schmidt telescope, located at La Silla Observatory in Chile, equipped with Yale's 10 square degree QUEST camera, we have been searching for distant Pluto-sized bodies out to distances of ~150 AU in the Southern Skies down to a limiting magnitude of 21.5 in R band.  To date the survey has covered ~10,000 square degrees south of the ecliptic. Using the SMARTS 1.3-m telescope, we have been further studying orbits and optical colors of our new discoveries...

08.27.2014 Yale scientists see the birth of a massive galaxy, hidden by dust
Graduate student Erica Nelson and her collaborators have discovered a window into the early, violent formation of the cores of the universe’s monster galaxies, obscured behind walls of dust, using the NASA/ESA Hubble Space Telescope and a telescope from the W.M. Keck Observatory in Hawaii. The discovery offers important clues about an early phase of galaxy development, from a time just 3 billion years after the Big Bang. The research appears in the journal Nature.

“The first black holes are believed to be remnants left behind after the first stars burned out completely,” said Priyamvada Natarajan, a Yale University professor of astronomy and physics. “The puzzle has been how these ‘seed’ black holes grew into the monsters that we now see within the time available, a few billion years at best.”
