Between Dec 19, 2024 and Jan 2, 2025, datasets can be submitted to DRUM but will not be processed until after the break. Staff will not be available to answer email during this period, and will not be able to provide DOIs until after Jan 2. If you are in need of a DOI during this period, consider Dryad or OpenICPSR. Submission responses to the UDC may also be delayed during this time.

    Did m2φ2 bite the dust? A closer look at ns and r
    (2015) Flauger, Raphael
    I will review measurements of the angular power spectrum of temperature perturbations from Planck data by the Planck collaboration and by Renee Hlozek, David Spergel and myself and will discuss the small differences in the scalar spectral index between the two. I will then combine these measurements with the recent measurement of the polarization of the cosmic microwave background by BICEP2 as well as the measurements of polarized emission from dust by the Planck collaboration to derive the current (but soon outdated) constraints on the spectral index of scalar perturbations and the amount of primordial gravitational waves. I will show that the data now disfavors the simplest model of inflation at 2-3 sigma depending on the choice of likelihood for the temperature data.
