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.
The International Commission on Physics Education is pleased to announce that the winner of the 2014 ICPE Medal for outstanding contributions to physics education is Professor Cedric Linder of Uppsala University, Sweden.
The award recognizes Professor Linder's outstanding contributions to physics education research. His work has been notable for its range, depth and impact, as well for its international scope. Educated at universities in South Africa, the USA and Canada, Cedric Linder, in 1996, was awarded the first personal Chair in Physics Education in South Africa. He moved to Uppsala University in 2000, becoming the first Professor of Physics Education Research in Sweden, while still retaining his professorship at the University of the Western Cape.
Active Galactic Nuclei (AGN) are fuelled by super-massive black holes residing in their centres, making them the most luminous (now extinct) galaxies in the universe. As part of her PhD thesis, Beatriz Villarroel has studied neighbours to two major types of AGN, to gain more insight into similarities and differences between theses types. According to a geometrical unification theory dating back to the 1980s, these two types are intrinsically similar objects, observed from different viewing angles (Type-1: pole-on; Type-2: edge-on). The present work identifies systematic differences in neighbours to Type-1 and Type-2 AGN, clearly showing that there are environmental (thus likely evolutionary) circumstances that influence the appearance of the AGN phenomenon.

In this talk , we consider all kinds of effective actions involving DBI, Chern-Simons and new Wess Zumino actions. Our aim is to provide a comprehensive explanation even for D- brane-anti D-brane systems.We then introduce various new techniques to derive allorder alpha' corrections to type II effective actions. The new actions effective actions /couplings are neither inside Myers‘ terms nor within pull-back/Taylor expansions.
The NASA Kepler survey has identified numerous Earth-size planets transiting other stars, and limited Doppler radial velocity measurements hint that many of these are primarily made of heavy, refractory elements, i.e. are "rocky". However, we have no direct measurements of the composition of these planets. The photospheres of Sun-like stars offer indirect information because the stars and protoplanetary disks have a common origin, and material accreted from a disk can change the abundances in the relatively thin convection zones of these stars. A strong correlation between giant planet occurrence and stellar metallicity has proved robust to scrutiny, but the underlying mechanism is unclear.
The presentation is given as part of the Neutron Resonance Analysis School I attended in 2011. I will present the general evaluation process; describe the resonance parameters and how they are represented in the ENDF format. Also, a brief description of the general theoretical models used in the analysis of neutron resonance data - R-matrix theory (the single-level Breit-Wigner, the multi-level Breit Wigner and Reich Moore approximation) for the resolve region and the Hauser-Feshbach theory for the unresolved resonance region will be covered. Finally, the Doppler broadening of the single level Breit-Wigner formalism for resonance absorption will be presented.
