A variety of observations suggest that magnetic fields are present in all galaxies and galaxy
clusters. These fields are characterized by a modest strength (10− 7–10− 5 G) and huge …

Magnetism is one of the four fundamental forces. However, the origin of magnetic fields in
stars, galaxies and clusters is an open problem in astrophysics and fundamental physics …

ABSTRACT A new, much-improved model of the Galactic magnetic field (GMF) is presented.
We use the WMAP7 Galactic synchrotron emission map and more than 40,000 extragalactic …

Aims. This work provides an update to existing reconstructions of the Galactic Faraday
rotation sky by processing almost all Faraday rotation data sets available at the end of the …

Significant new opportunities for astrophysics and cosmology have been identified at low
radio frequencies. The Murchison Widefield Array is the first telescope in the southern …

The past several years have seen the emergence of a standard cosmological model, in
which small temperature differences in the cosmic microwave background (CMB) radiation …

ABSTRACT The Canadian Galactic Plane Survey (CGPS) is a project to combine radio,
millimeter, and infrared surveys of the Galactic plane to provide arcminute-scale images of …

We have re-analyzed the NRAO VLA Sky Survey (NVSS) data to derive rotation measures
(RMs) toward 37,543 polarized radio sources. The resulting catalog of RM values covers the …

Context. Our position inside the Galaxy requires 3D-modelling to obtain the distribution of
the Galactic magnetic field, cosmic-ray (CR) electrons and thermal electrons. Aims. Our …

The large-scale magnetic field of our Galaxy can be probed in three dimensions using
Faraday rotation of pulsar signals. We report on the determination of 223 rotation measures …
