SUMMARY:The magnetic interstellar medium: cosmological and astrophysic
 al perspectives\, Atomic Physics Seminar\, Susan Clark\, Institute for
  Advanced Study
DESCRIPTION:The interstellar medium (ISM) is multi-phase\, turbulent\,
  and magnetic. This makes the ISM an ideal laboratory for studying the
  multi-scale physics of star formation and galactic evolution. This un
 fortunately also makes the ISM a formidable foreground for cosmology e
 xperiments\, such as the search for inflationary gravitational wave B-
 mode polarization in the cosmic microwave background. I will discuss r
 ecent work on magnetic fields in the diffuse ISM\, with a particular f
 ocus on insights from high-dynamic range observations of neutral hydro
 gen and polarized dust emission. Novel tools for quantifying the morph
 ology of interstellar material are enabling new probes of the ambient 
 magnetic field structure\, and thus a better characterization of polar
 ized cosmological foregrounds. The hunt for primordial signals is now 
 inextricably linked to our understanding of the magnetic ISM.    <br>
