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.

07.17.2014 Charting the heavens like never before, via Sloan Digital Sky Survey
Yale University scientists are involved all of the major aspects of the Sloan Digital Sky Survey, an initiative that spans four continents and includes 200 astronomers at more than 40 institutions. They will chart thousands of nearby galaxies, probe the composition of stars throughout the Milky Way with novel clarity, and measure the expansion of the universe during a particularly murky period.
07.11.2014 Yale astronomers find seven galaxies using camera lenses
The astronomy project, using eight telephoto lenses lashed together, turned up seven new galaxies, but so far it’s unknown how far away they are. That’s why the scientists have rented time on the giant space-based Hubble telescope “to see if Hubble can find individual stars in the galaxies,” he said. That will tell them how far away the galaxies are. It’s a difficult task because the galaxies are all diffuse in nature.
05.20.2014 Liang Yu, '14 B.S. has been awarded the Beckwith Prize from the Astronomy Department.
The prize is awarded to the undergraduate most proficient in some branch of astronomy or mathematics. In addition to the Beckwith Prize, Liang also was awarded Exceptional Distinction in the Major. Congratulations Liang!
