Optimal Radio Window for the Detection of Ultra-High-Energy Cosmic Rays and Neutrinos off the Moon

O. Scholten, J. Bacelar, R. Braun +4

When high-energy cosmic rays impinge on a dense dielectric medium, radio waves are produced through the Askaryan effect. We show that at wavelengths comparable to the length of the…

Properties of the warm magnetized ISM, as inferred from WSRT polarimetric imaging

M. Haverkorn, P. Katgert, A. G. de Bruyn

We describe a first attempt to derive properties of the regular and turbulent Galactic magnetic field from multi-frequency polarimetric observations of the diffuse Galactic synchro…

HI kinematics in a massive spiral galaxy at z=0.89

L. V. E. Koopmans, A. G. de Bruyn

We present a kinematic model of the neutral-hydrogen in the spiral galaxy of the lens system PKS1830-211, based on a Multi Element Radio-Linked Interferometer (MERLIN) 1.4-GHz radi…

Annual modulation in the scattering of J1819+3845: peculiar plasma velocity and anisotropy

J. Dennett-Thorpe, A. G. de Bruyn

We present two years of monitoring observations of the extremely variable quasar J1819+3845. We observe large yearly changes in the timescale of the variations (from ~ 1 hour to ~…

Extrinsic Radio Variability of JVAS/CLASS Gravitational Lenses

L. V. E. Koopmans, A. Biggs, R. D. Blandford +6

We present flux-ratio curves of the fold and cusp (i.e. close multiple) images of six JVAS/CLASS gravitational lens systems. The data were obtained over a period of 8.5 months in 2…
