Astrophysics

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

While nuclei lighter than iron are fused over the course of typical stellar evolution, almost half of the elements heavier than iron are created through the rapid neutron capture process (r-process). These nuclei are thought to be produced in...

Abstract: The concept that there may exist symmetries relating bosons and fermions was first proposed by Yuri Golfand and Evgeny Likhtman in 1971 and independently realized by Julius Wess and Bruno Zumino in 1974. Thus, was born the topic of...

Abstract: The theory of General Relativity has successfully passed a large number of observational tests. The theory has been extensively tested in the weak-field regime with experiments in the Solar System and observations of binary pulsars. The...

Data from ESA’s Gaia mission is already revolutionizing Galactic astronomy, providing an unprecedented view of the Solar neighborhood and beyond. However, while it provides us a great opportunity to transform our understanding of the Milky Way, it...

Alfvén waves, a fundamental mode of magnetized plasmas, are ubiquitous throughout our heliosphere. The non-linear behavior of these modes may play key roles in the physics of the turbulent solar wind, heating of the solar corona, and the behavior of...
