High - resolution radio observations of RCW 49

High-resolution radio continuum observations of the southern H II complex RCW 49 are presented. The observations were carried out with the Molonglo Observatory Synthesis Telescope (MOST) at 0.843 GHz, and the Australia Telescope Compact Array (ATCA) at 1.38 and 2.38 GHz. Two wind-blown shells have been discovered in the core region of RCW 49, the more massive of which surrounds the Westerlund 2...

Atomic-scale observations of alloying at the Cr-Fe(001) interface.

While much progress has been made using epitaxial growth of Fe/Cr/Fe structures to study magnetic exchange coupling, a number of anomalies have arisen in studies of this model system. Using scanning tunneling microscopy and spectroscopy to investigate Cr growth on Fe(001), we have identified a potential structural cause of these anomalies. We show that Cr growth under layer-by-layer conditions ...

ALMA Memo 592 V1.0: The Power Spectrum of Atmospheric Path Fluctuations at the ALMA Site from Water Vapour Radiometer Observations

This memo investigates the properties of atmospheric turbulence above the ALMA site using measurements from the Water Vapour Radiometers (WVRs), in particular testing the Kolmogorov turbulence model and searching for evidence of an outer length scale. We fit model power-spectral density (PSD) curves to the measured power spectra for a number of observations and extract the slope, the amplitude ...

GHz VLBI OBSERVATIONS OF 3 C 120

We present the first 86 GHz VLBI observations of the radio galaxy 3C 120, together with contemporaneous 43 and 22 GHz polarimetric VLBA observations. The very high angular resolution obtained at 86 GHz provides an upper limit to the size of the core of 54 mas (0.025 h pc). This represents a direct determination of the base of the jet that is independent of variability arguments (which depend on...

Ordered fragmentation of oxide thin films at submicron scale

Crack formation is typically undesirable as it represents mechanical failure that compromises strength and integrity. Recently, there have also been numerous attempts to control crack formation in materials with the aim to prevent or isolate crack propagation. In this work, we utilize fragmentation, at submicron and nanometre scales, to create ordered metal oxide film coatings. We introduce a s...
