Introduction:

Neutrino oscillations have been confirmed in many experiments in the last two decades. Almost all the observed oscillations fit quite well in the standard three neutrino picture where we have electron, tau and muon ”type or flavour” neutrinos. Oscillations can occur as the flavour of the neutrino does not correspond to a distinct massive particle. The distinct mass-state neutrinos are the physical particles that move freely through space and are made up of a combination of electron, tau and muon flavour neutrinos. So if you observe a neutrino in flight, you might observe the muon component one time, and the electron component the next. It is this change of neutrino flavour over time that we call neutrino oscillations.

Planck intermediate results. XXX. The angular power spectrum of polarized dust emission at intermediate and high Galactic latitudes by R. Adam et al.

Introduction:

One of the most exciting news of this year was the recent claim from the BICEP2 experiment of an indirect measurement of primordial gravitational waves. The experiment is based in the South Pole and designed to measure the polarization of the cosmic background radiation, focusing on the so-called B-modes. These modes can give insight on the physics of early stages of the Universe. In particular, inflationary theories predict the existence of a gravitational wave background which in turn can be seen nowadays as B-modes of polarized cosmic radiation. Unfortunately, there are other sources of B-modes, such as synchrotron radiation, gravitational lensing or polarized thermal emission from diffuse galactic dust.

In this paper, the Planck collaboration presents measurements of the polarized dust angular power spectra. Dust is considered the main background of B-modes at some of frequencies at which the BICEP2 experiment is operating (150 GHz). However, the BICEP2 collaboration found that the galactic dust cannot explain by itself their measurements, claiming therefore an observation of primordial B-modes.

Geneva, 4 November 2014. At its 173rd Closed Session today, CERN Council selected the Italian physicist, Dr Fabiola Gianotti, as the Organization's next Director-General. The appointment will be formalised at the December session of Council, and Dr Gianotti's mandate will begin on 1 January 2016 and run for a period of five years. Council rapidly converged in favour of Dr Gianotti.

Background model systematics for the Fermi GeV excess by Francesca Calore, Ilias Cholis and Christoph Weniger

October 1, 2014 by tiinatimonen

Introduction:

The Fermi-LAT Space Telescope looks deeply inside the high energy cosmos providing a detailed picture of the Universe's most extraordinary phenomena. Among its powerful discoveries (blazars, active galaxies, gamma-ray bursts, neutron stars and even high energy eruptions from our own Sun) the most surprising and challenging one is an excess in gamma-rays coming from the center of our Galaxy, that cannot be explained with the standard astrophysical background. What are these unexpected high energy messengers telling us?
