A new high resolution spectrometer

In March 2011, our group, together with Andrei Tokovinin at CTIO, built and commissioned a high-resolution spectrometer, CHIRON.

CHIRON is a highly stable cross-dispersed echelle spectrometer deployed at CTIO 1.5m telescope. It is fed by fiber and intended primarily for precise radial velocities.

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.
08.07.2014 How do you feed a hungry quasar? With a ‘super boost,’ scientists say
“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.”
