Gunnar Källén

2013-2014


Sep 2013: Scott Tremaine

Scott Tremaine (Institute for Advanced Study, Princeton) is well known for his important contributions to a broad range of topics in astrophysics. His work covers breakthrough publications on planetary dynamics, the structure of the Milky Way and the cosmological evolution of galaxies.

He has been awarded several prestigious prizes, such as the Dannie Heinemann Prize for Astrophysics and the Brouwer Award.

His seminar, titled 'Black holes in nearby galaxies', is planned for Thursday 12/09/2013, at 14:15 in Lundmarksalen (Lund Observatory).

Nov 2013: Ken Freeman

Professor Ken Freeman (ANU College of Physical and Mathematical Sciences, Canberra) has worked dominantly in the field of galactic astronomy and made a big impact with his studies on dark matter.

Most recently he was awarded the 2012 Prime Minister's Prize for Science .

His seminar, titled 'Galactic Archaeology and Chemical Tagging', is planned for Wednesday 27/11/2013, at 11:15 in Lundmarksalen (Lund Observatory).

Feb 2014: Karin Öberg

Karin Öberg (Harvard-Smithsonian Center for Astrophysics) has made several important contributions to our understanding of chemistry in star-forming regions and protoplanetary disks. In The Öberg Astrochemistry Group at Harvard, she combines observations and laboratory experiments to explore the properties and origins of ices in space. Recently, she and her colleagues made the first unambigous detection of a CO ice line, which has important implications for planet formation and the hunt for new extrasolar planets.

See here for more information about Karin Öberg and The Öberg Astrochemistry Group at Harvard.

Her seminar, titled 'Icy origins: the chemistry of planet formation', is planned for Thursday 27/02/2014, at 14:15 in Lundmarksalen (Lund Observatory).


Apr 2014: Michael Perryman

Professor Michael A.C. Perryman (University College, Dublin) was the project scientist at ESA for Hipparcos (1981-1997) and Gaia (1995-2006). Author of "Astronomical Applications of Astrometry" (2009) and "The Exoplanet Handbook" (2011) he is an authority on exoplanet science as well as astrometry. The development of superconducting optical detectors is another of his many research interests. In 2010 he received an honorary doctorate at Lund University, and in 2011 the Tycho Brahe Prize of the European Astronomical Society. He is presently (late 2013) a Bohdan Paczynski Visiting Professor at the Princeton University.

His seminar, titled 'Astrometry: its history and scientific importance today', is planned for Thursday 24/04/2014, at 14:15 in Lundmarksalen (Lund Observatory).
