SUMMARY:Inflation after Planck 2015 - George Efstathiou
DTSTART:20150211T141500Z
DTEND:20150211T151500Z
UID:TALK56421@talks.cam.ac.uk
CONTACT:Mahdi Godazgar
DESCRIPTION:I will review some of the key science results from the 2015 Pl
 anck data release of last week. One of the exciting results of 2014 was th
 e BICEP2 detection of B-mode anisotropies. I will review the new joint ana
 lysis of BICEP2/Keck Array/Planck data that quanties the level of polarize
 d dust emission in the BICEP2 field. At present\, there is no convincing e
 vidence of gravitational waves from inflation. The Planck 2015 results are
  consistent with simple single-field models of inflation\, with purely adi
 abatic perturbations and low tensor-to-scalar ratio of r<0.09.
