CARAD: Computer-aided Analysis of Radio Astronomy Data
Radio astronomy studies celestial objects by detecting their radio frequency emissions, enabling observation of phenomena invisible at other wavelengths. Next-generation telescopes generate unprecedented data volumes that challenge traditional analytical approaches. Manual inspection and classical …

Optical detection and analysis of Pictor A's jet
… from the Hubble Space Telescope of the FRII radio galaxy Pictor A reveal a number of jet knot candidates which coincide with previously detected radio and x-ray knots. Previous observations in x-ray and radio bands show the entire jet to be 1.90 long, with interesting variability, but an …

Full Mueller imaging: direction dependent corrections in polarimetric radio imaging
… largest gravitationally bound structures such as galaxy clusters [1]. The magnetic fields play a vital role in the evolution of these astronomical systems. In addition to the multitude of scales, magnetic fields are present in different astronomical systems of varying strengths. The strongest …

The nucleus of Centaurus A
… A (NGC 5128) is the nearest massive elliptical galaxy, the nearest radio galaxy, and the nearest recent merger. It is the ideal laboratory to study the connection between merging, massive black holes, the source of radio jets, and merger-induced star formation in detail. Using Naos-Conica and …

A statistical approach to automated detection of multi-component radio sources
Advances in radio astronomy are allowing for deeper and wider areas of the sky to be observed than ever before. Source counts of future radio surveys are expected to number in the tens of millions. Source finding techniques are used to identify sources in a radio image, however, these techniques …

Astronomical Interferometry at Submillimetre Wavelengths
… candidate Sagittarius A* at the centre of our galaxy, and the nearby radio-galaxy Centaurus A. This is followed by a more detailed analysis of data for the evolved star VY CMa and observations of discs around young stars. Spectra of the 321 GHz H20 line from VY CMa confirm that maser …

Cluster Weather Vanes: Radio Galaxies as Indicators of Galaxy Cluster Dynamics
… of such jets with dynamical features of galaxy cluster media such as winds and shock waves, and to use the recognizable observed features as diagnostic tools when examining real radio sources in clusters to better understand the state of the environment surrounding radio galaxies (RG). We …
