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.
Studying red giant stars tells astronomers about the future of the Sun and about how previous generations of stars spread the elements needed for life across the Universe. One of the most famous red giants in the sky is called Mira and lies about 400 light-years from Earth. Sofia Ramstedt is leading an international project to study binary red giant stars with ALMA and Mira is part of that study. The new high-resolution images reveal the close interaction between Mira and its companion. Despite their rather large separation, the two stars have had a strong effect on one another and the new images demonstrate how double stars can influence their environments and leave clues for what will be their future fate.
The image has been selected as ESO’s picture of the week:
Date: 20 December
Time: 18:00 h
Place: Matverkstan (http://www.mat-verkstan.se/matverkstan-pa-ultuna/)
The Christmas Party this year will, as ususal, be a traditional one with glögg, christmas food, drinks and live music.
The participation is free for staff/students. You may bring a guest for a fee of 200 SEK, to be paid to Marja Fahlander for IFA divisions and Britt Högberg for TSL.
Using the pure-spinor formalism, Berkovits and Fleury have
recently found leading-order expressions for the supergravity vertex operators in an AdS_5 x S^5 background. In this talk, after briefly reviewing their work, I will present the first application of their results, showing that a well-known harmonic superspace coupling can be obtained as the result of a superstring scattering amplitude computation involving open and closed superstring vertex operators in AdS_5 x S^5.
