From 6th to 8th July 2011 the Leibniz-Institut für Astrophysik Potsdam (AIP) hosted the Workshop GALACTIC ARCHAEOLOGY WITH SEGUE, organized by Dr. Cristina Chiappini (Chair), Dorothée Brauer and Dr. Arman Khalatyan.

 

SEGUE-2, an already completed SDSS-III survey that is the continuation of the SDSS-II Sloan Extension for Galactic Understanding and Exploration (SEGUE), measured medium-resolution (R ≈ 1800) optical spectra of around 200,000 stars in a variety of target categories, probing chemical evolution, stellar kinematics and substructure, and the mass profile of the dark matter halo from the solar neighbourhood to distances of 100 kpc. Together SEGUE-1 and SEGUE-2 have gathered around 500,000 spectra of stars in the Milky Way. SEGUE is complementary to the RAVE survey, which provides higher resolution data for brighter objects more concentrated in the solar neighbourhood.

The SEGUE workshop counted with the participation of 25 international researchers, among which the SEGUE Survey Principal Investigator, Dr. Constance Rockosi, Associate Professor at the University of California, Santa Cruz (UCO/Lick Observatory), and of the SEGUE Survey Scientist, Dr. Timothy Beers, Professor at the Michigan State University.

The AIP is part of SDSSIII as part of the German Participation Group.

Dr. Cristina Chiappini, staff scientist at AIP, is a SDSSIII member via the Brazilian Participation Group.

 

The key topics of the Leibniz Institute for Astrophysics are cosmic magnetic fields and extragalactic astrophysics. A considerable part of the institute's efforts aim at the development of research technology in the fields of spectroscopy, robotic telescopes, and e-science. The AIP is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory of Potsdam founded in 1874. The latter was the world's first observatory to emphasize explicitly the research area of astrophysics.The AIP is a foundation according to civil law and is a member of the Leibniz Association. The Leibniz Association is a network of 87 independent research institutes and scientific service facilities, which strive for scientific solutions for major social challenges.
