| New Phased-Array Feed on ASKAP antenna 2 |
| by the ASKAP team (CASS) |
| The new Phased-Array Feed (PAF) now installed
in the focus of ASKAP antenna 2. The beautiful chequerboard pattern shows the
188 dipole elements used to form 36 beams, each with ~1 degree field of view.
Together these 36 PAF beams allow us to observe 30 square degrees of the sky
in on pointing, making radio continuum images and HI data cubes. - HI is the
21-cm spectral line of neutral hydrogen, one of the key ingredients of spiral
galaxies like the Milky Way.
