Planck 2013 results. XIII. Galactic CO emission

Xin Chen, Julien Lesgourgues, Fabio Finelli

Rotational transition lines of CO play a major role in molecular radio astronomy as a mass tracer and in particular in the study of star formation and Galactic structure. Although a wealth of data exists for the Galactic plane and some well-known molecular ...

Joint Planck and WMAP CMB map reconstruction

Jean-Luc Starck, Anaïs Marie Rassat

We present a novel estimate of the cosmological microwave background (CMB) map by combining the two latest full-sky microwave surveys: WMAP nine-year and Planck PR1. The joint processing benefits from a recently introduced component separation method coine ...

Searches For High-Energy Neutrino Emission In The Galaxy With The Combined Icecube-Amanda Detector

Shirit Cohen, Matthias Wolf, Mathieu Ribordy, Xiaoxia Bai

We report on searches for neutrino sources at energies above 200 GeV in the Northern sky of the Galactic plane, using the data collected by the South Pole neutrino telescope, IceCube, and AMANDA. The Galactic region considered in this work includes the loc ...

Low-l CMB analysis and inpainting

Jean-Luc Starck, Anaïs Marie Rassat

Reconstructing the cosmic microwave background (CMB) in the Galactic plane is extremely difficult due to the dominant foreground emissions such as dust, free-free or synchrotron. For cosmological studies, the standard approach consists in masking this area ...

Diffuse gamma-ray constraints on dark matter revisited I: the impact of subhalos

Steve Blanchet

We make a detailed analysis of the indirect diffuse gamma-ray signals from dark matter annihilation in the Galaxy. We include the prompt emission, as well as the emission from inverse Compton scattering whenever the annihilation products contain light lept ...

A comment on the emission from the Galactic Center as seen by the Fermi telescope

Alexey Boyarsky, Oleg Ruchayskiy

In the recent paper of Hooper and Goodenough (2010) [10] it was reported that gamma-ray emission from the Galactic Center region contains an excess compared to the contributions from the large-scale diffuse emission and known point sources. This excess was ...

Search for dark matter from the Galactic halo with the IceCube Neutrino Telescope

Shirit Cohen, Matthias Wolf, Mathieu Ribordy, Xiaoxia Bai

Self-annihilating or decaying dark matter in the Galactic halo might produce high energy neutrinos detectable with neutrino telescopes. We have conducted a search for such a signal using 276 days of data from the IceCube 22-string configuration detector ac ...

The cosmic decline in the H2/HI ratio in galaxies

Danail Obreschkow

We use a pressure-based model for splitting cold hydrogen into its atomic (HI) and molecular (H2) components to tackle the co-evolution of HI, H2, and star formation rates (SFR) in 3x10^7 simulated galaxies in the Millennium simulation. The main prediction ...

Simulations of galactic disks including a dark baryonic component

Yves Revaz, Daniel Pfenniger

The near proportionality between HI and dark matter in outer galactic disks prompted us to run N-body simulations of galactic disks in which the observed gas content is supplemented by a dark gas component representing between zero and five times the visib ...
