The Paul Wild Observatory, near Narrabri, is part of the
Australia Telescope National Facility (ATNF), and operated by the
CSIRO; the Officer-in-Charge is Dr Graham Nelson. The Narrabri site
contains the Australia Telescope Compact Array, which consists of five
antennas located along a 3-km railtrack, and a 6th antenna 3 km further
to the west.
CSIRO's Australia Telescope National Facility (ATNF) is an
organisation that supports and undertakes research in radio astronomy.
It operates the Australia Telescope, the collective name for a set of
radio telescopes in New South Wales. These telescopes are used,
individually or together, to study objects in the Universe ranging from
the remains of dead stars to entire galaxies.
The CSIRO Australia Telescope National Facility operates a
group of radio telescopes collectively known as the Australia
Telescope. The ATNF Parkes Observatory consists of a 64m telescope
which is used as an independent instrument, and networked with other
Australian and international radio telescopes for VLBI.
SUMSS is a deep radio survey of the entire sky south of
declination -30 degrees, made using the Molonglo Observatory Synthesis
Telescope, operating at 843MHz and recording right-circular
SUMSS matches (approximately) the resolution and depth of the NRAO-VLA
Sky Survey (NVSS). The principal data products are mosaics which cover
a 4x4 degree square on the sky. The centres of the mosaics mirror the
NVSS centres in the north. The resolution is 45" x 45"/sin(dec), and
the rms noise limit varies from 1.3 to 2mJy/beam (lower toward the
south celestial pole).
The survey began in March 1997 and will take eight years to complete.
SUMSS is suported by funding from the Australian Research Council.
The primary reference for a description of the survey is: Bock,
D., Large, M. and Sadler, E.
