Radio observational constraints on Galactic 3D-emission models

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 intention is to find a Galactic 3D-model which agrees best with available radio observations. Methods. We constrain simulated all-sky maps in total intensity, linear polarization, and rotation measure (RM) by observat...

New mechanism of pulsar radio emission.

It is shown that pulsar radio emission can be generated effectively through a streaming motion in the polar-cap regions of a pulsar magnetosphere causing non-resonant growth of waves that can escape directly. As in other beam models, a relatively low-energy high-density beam is required. The instability generates quasitransverse waves in a beam mode at frequencies that can be well below the res...

A Generic Pulsar Radio Emission Mechanism

A generic interpretation of pulsar radio emission that does not rely on the identification of a specific emission mechanism is explored. Coherence is quantified in terms of a coherence factor, which implies a maximum brightness temperature; the possible significance of Poincaré invariants is pointed out, and the potential use of higher order moments of the intensity to measure the coherence is ...

Radio continuum emission and magnetic fields

We observed the non-interacting edge-on galaxy NGC 5907 in total power and polarized radio continuum emission at wavelengths of λλ 2.8, 6.2, and 20 cm, using the VLA and the Effelsberg 100-m telescope. The total power emission of the galaxy shows (after subtraction of a double background source in the southern half) its maximum intensity slightly shifted to the north with respect to the optical...

Probing Star Formation at Low Metallicity: the Radio Emission of Super Star Clusters in Sbs0335−052

We present high-resolution radio continuum observations of the nascent starburst in the metalpoor galaxy SBS 0335−052. These radio data were taken with the Very Large Array and include observations at 0.7 cm, 1.3 cm, 2 cm, 3.6 cm, and 6 cm. These observations enable us to probe the thermal radio nebulae associated with the extremely young star-forming regions in this galaxy. Two discrete and lu...
