First ASKAP 36-beam image ! |
by the ASKAP team (CASS) |
This radio image of a region in the
constellation of Apus was made with nine ASKAP antennas, each of which was
equipped with a second-generation Phased-Array Feed (PAF). The PAFs were
configured with 36 dual-polarisation beams arranged in a square pattern and
rotated on the sky. The 9-antenna ASKAP array observed a single field for
11 hours with 48 MHz of bandwidth centered at 939.5 MHz. This continuum
image, which was produced with ASKAPsoft, has an r.m.s of around 300
μJy/beam and a field of view of 30 square degrees. It contains over
1300 sources. - Image credit: Wasim Raja. For more information see the latest ASKAP News. |
