The department of Physics and Astronomy was formed in January 2010 by merging the former department of Physics and Astronomy with the department of Physics and Materials Science.
The department of Physics and Astronomy has assignments within three main areas; education, research and cooperation with society, carried out within Applied nuclear physics, Astronomy and space physics , High Energy Physics, Ion Physics, Materials Physics, Materials Theory, Molecular and Condensed Matter Physics,
Nuclear Physics, Physics Education Research and Theoretical physics.
You find us at the Ångström laboratory in Uppsala.
After seven years of preparation, the ESA cornerstone mission Gaia was successfully launched from French Guyana at 1012 h (CET) on the 19th of December. It is now on its way to Lagrange point 2, 1.5 million kilometers outside Earth's orbit.
Several scientists from the Department of Physics and Astronomy have had active roles in the Gaia Data Processing and Analysis Consortium (DPAC), a team of some 400 scientists around Europe which has prepared the software side of the mission. Soon, this software will be put to the test on actual Gaia data. This moment is of course anxiously awaited.
Lyman alpha is the intrinsically strongest emission line of astrophysical nebulae. Its rest wavelength in the far UV makes it accesbile from the ground out to large redshifts and Lyman alpha is today the primary tool by which high redshift galaxies are indentified. However, the line is a resonant one and becomes optically thick already at moderate neutral hydrogen densities. Consequently, Lyman alpha radiative transport through galaxies is a complex problem, where the structure, dust content and kinematics of the ISM all matter. We have started LARS - the Lyman Alpha Reference Sample - a project on HST studying Lyman alpha in local galaxies in great detail.
The European electricity market is in a flux. 2013, many European companies and countries struggle to achieve cost competitiveness, and create environments for healthy profitability and sound fundamentals for the states to ensure a good welfare. The electricity market is in many ways part of this. Thus, any discussion on market design must emanate from 2013, and from the (global) cost competitiveness of the electricity system discussed. Thus, the issue is not only how much burden the European customers can bear (affordability) but whether proposed solutions are long run viable. European electricity producers compete with the rest of the world on the manufacturing and energy intensive industry.
The upgrade of the ESS linear accelerator to produce the world’s most intense neutrino Super Beam – a challenge
The European Spallation Source in Lund is based on what will be the world’s most powerful linear proton accelerator. This accelerator will produce a 2 GeV proton beam of 5 MW to be sent to a spallation target to provide the world’s most intense production of pulsed neutrons to be used for basic and applied material research. The linac duty factor required for such operation is low (4 %) which will permit increasing the linac pulse frequency from 14 Hz to 28 Hz. The extra pulses will be sent to another target with the aim to produce an intensive neutrino Super Beam with the potential of providing unprecedented opportunities for fundamental neutrino-physics research.
