13
Discovering Solar System objects with the SDSS SN Survey ! Objects that move are nearby!
14
… and unusual ones!
15
In progress: BOSS -- ripples in distant galaxies Extending the 3D map to larger distances == farther back in time Use this to try to study the nature of dark energy
16
In progress: MARVELS -- a survey for extrasolar giant planets Measure velocities of 5000-10000 stars (60 at a time) 30 different times over two years Variations in velocity indicate the presence of planets Large sample of stars used to get better statistics on what types of stars have planets
17
Coming soon: APOGEE -- The Disk of the Milky Way High resolution infrared spectroscopy of 100,000 stars Measure abundances of 10-20 different elements Clues about star formation and history of star formation of the Milky Way
