Overview of the Planck Mission |
|
|
Planck launched in 2009 and in March 2013 released the first set of cosmological data, along with a series of papers. As well as determining the cosmological parameters with increased precision, Planck: measures several new types of signal which probe the evolution of structure; provides an all-sky catalogue of sources; and provides unique ways to study the large-scale properties of our own Galaxy. |

Bond, J. Richard |
Fundamental Physics from the Planck Satellite |
|
|
Our Planck collaboration, with CSA involvement, recently released its first cosmological results. I will talk about the constraints we derived on early and late universe inflation, including on the shape of the primordial power spectrum, on popular inflaton potentials, and on patterns of primordial non-Gaussianity. The dramatic large scale anomalies persistent through COBE, WMAP and Planck could have an early universe explanation. Dark energy trajectories remain compatible with no late-inflaton kinetic energy (i.e., a pure vacuum potential, aka Einstein's cosmological constant) but await a supernova legacy survey update. |

The Planck Lensing Potential |
|
|
The high-resolution CMB fluctuations measured by the Planck satellite are gently perturbed by gravitational lensing, primarily sourced by the structure of the Universe on very large scales (>30Mpc comoving) at high redshifts (z~2). We have exploited the distinct statistical signatures of this effect to construct a projected, full-sky map of the the large-scale dark matter distribution, as well as an integrated measure of the matter power spectrum. In this talk I will detail our measurement, as well as its implications for cosmology. |

Planck’s impact on interstellar medium science |
|
|
By virtue of its multifrequency all-sky mapping to probe the CMB, Planck has also produced marvellous maps of the foreground emission from the Galaxy, with unprecedented sensitivity and resolution. I will present highlights of what we are learning about thermal dust emission, including its polarization, anomalous microwave emission, and CO. |
