Frontiers in Cosmic Magnetism and in Many-Body Physics

Susan Clark & Vedika Khemani (Stanford University) via zoom

Galaxies like our Milky Way host large-scale, weak magnetic fields. The interstellar magnetic field affects a wide range of physics, from cosmic ray propagation to star formation. The magnetic interstellar medium is also a formidable foreground for experimental cosmology, particularly for the quest to find signatures of inflation in the polarized cosmic microwave background.
