Fields of streams

New Milky Way Tidal Stream in Triangulum

Ana Bonaca, Marla Geha, Nitya Kallivayalil

"Stellar streams are found throughout the outer region of the Milky Way.  They are presumed to originate from disrupting dwarf galaxies or globular clusters.  We have discovered a new stellar stream in the Milky Way using the Sloan Digital sky survey 3 all-sky imaging, which we call the Triangulum Stream.  Kinematic studies of this and similar strams will provid tight constraints on the strenght, shape and lumpiness of the Galacitc gravitation potential."

“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.”

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.
