The Radio Observatory of ASTRON (The Netherlands Institute for Radio Astronomy) invites the world-wide community to submit Expressions of Interest to define, prepare and perform large survey programmes with Apertif, the new Phased Array Feed receiver system for the Westerbork Synthesis Radio Telescope. The WSRT and Apertif serve as a scientific and technological pathfinder for the Square Kilometre Array.

Published by the editorial team, 22 June 2010

The submission of Expressions of Interest by the community is the initial step toward selecting and defining large surveys that will take full advantage of the strengths of the WSRT equipped with Phased Array Feeds.

Apertif will enlarge the instantaneous Field-of-View for twelve of the fourteen 25-metre WSRT dishes to 8 square degrees, increasing the current WSRT Field-of-View by a factor of 30 and the survey speed of the telescope by a factor 20. This enables astronomers to conduct surveys covering large parts of the radio sky while retaining benefit of the high resolution of a radio interferometer.

The call for Expressions of Interest for Apertif surveys can be found here.

Our renewed ‘Melkwegpad’ (Milky Way Path) is finished! The new signs have texts in Dutch on the one side and in English on the other side. The signs concerning planets have a small, 3D printed model of that planet in their centre.

The background drawing shows how the subband correlator calculates the array correlation matrix. In the upper left the 4 UniBoard2s we used. The two ACM plots in the picture show that the phase differences of the visibilities vary from 0 to 360 degrees.

One of the key specifications of LOFAR2.0 is measuring using the low- and the highband antenna at the same time. For this measurement we used 9 lowband antenna and 3 HBA tiles.
