The LOFAR Transients Key Project
Rob Fender, Robert Braun, Ben Stappers +18
LOFAR, the Low Frequency Array, is a new radio telescope under construction in the Netherlands, designed to operate between 30 and 240 MHz. The Transients Key Project is one of the…
Aperture Arrays for the SKA: Dense or Sparse?
Robert Braun, Wim van Cappellen
We briefly consider some design aspects of aperture arrays for use in radio astronomy, particularly contrasting the performance of dense and sparse aperture arrays. Recent insights…
A very brief description of LOFAR - the Low Frequency Array
H. Falcke, M. P. van Haarlem, A. G. de Bruyn +28
LOFAR (Low Frequency Array) is an innovative radio telescope optimized for the frequency range 30-240 MHz. The telescope is realized as a phased aperture array without any moving p…
The Westerbork SINGS Survey: I. Overview and Image Atlas
Robert Braun, Tom Oosterloo, Raffaella Morganti +2
We have obtained moderately deep radio continuum imaging at 18 and 22cm with the Westerbork array of 34 nearby galaxies drawn from the Spitzer SINGS and Starburst samples to enable…
The Effect of Star Formation on the Far-Infrared--Radio Correlation within Galaxies
E. J. Murphy, G. Helou, R. Braun +13
Using data obtained for twelve galaxies as part of the {\it Spitzer} Infrared Nearby Galaxies Survey (SINGS) and the Westerbork Synthesis Radio Telescope (WSRT)-SINGS radio continu…
Phenomenological Modeling of the FIR-Radio Correlation within Nearby Galaxies
E. J. Murphy, G. Helou, L. Armus +3
We present an analysis of the far-infrared (FIR)-radio correlation within a group of nearby star-forming galaxy disks observed as part of the {\it Spitzer} Infrared Nearby Galaxies…
