2D Ferromagnetism in the High-Tc Analogue Cs_2AgF_4
S. E. McLain, D. A. Tennant, J. F. C. Turner +5
Although the precise mechanism of high-Tc superconductivity in the layered cuprates remains unknown, it is generally thought that strong 2D Heisenberg antiferromagnetism combined w…
A massive star-forming region in a very early stage of evolution
K. J. Brooks, G. Garay, D. Mardones +2
We present results from a study of two luminous IRAS sources thought to be young massive star-forming regions and which have no previously detected radio continuum emission: IRAS 1…
Searching for Clusters of Galaxies with SUMSS
H. J. Buttery, G. Cotter, R. W. Hunstead +1
Statistical overdensities of radio sources in the NRAO VLA Sky Survey (NVSS) catalogue have proven to be signposts to high-redshift clusters of galaxies. A similar search for overd…
Radio Observations of Merging Clusters in the Shapley Concentration
T. Venturi, S. Bardelli, G. Zambelli +2
In this paper we present the first results of a radio survey at 22 cm in the central region of the Shapley Concentration, carried out with the Australia Telescope Compact Array. In…
