SUMMARY:Johanna Nagy (Case Western) "Probing Inflation with SPIDER\, a Balloon-Borne CMB Polarimeter"
DESCRIPTION:Abstract:\n \nThe generation of a stochastic gravitational wave background is a key prediction of cosmological theories of inflation. At large angular scales\, these gravitational waves imprint a “B-mode” polarization pattern in the Cosmic Microwave Background\, providing a new window into the physics of the early universe and helping to constrain and distinguish between inflationary models. SPIDER is a balloon-borne telescope that has been uniquely optimized to search for the inflationary B-mode signature in the CMB. Over the course of two Antarctic flights\, SPIDER will make polarization maps over 10% of the sky in three frequency bands with degree-scale angular resolution. After an overview of the instrument and science goals\, preliminary results from SPIDER’s 2015 flight will be presented along with a summary of progress towards the second flight.
