Cryogenic Filters for RFI Mitigation in Radioastronomy
RFI mitigation in Radioastronomy can be achieved adopting cryogenic filters in appropriate typologies. A study has been conducted in L, C and X band with the evaluation of the filter architecture in copper, with theoretical estimation, computer simulations, prototypes realization, laboratory measurements. Such work has been preliminary to the realization of HTS samples with the purpose of a sim...
متن کاملRadioastronomy Image Synthesis on the Cell/B.E
Now that large radiotelescopes like SKA, LOFAR, or ASKAP, become available in different parts of the world, radioastronomers foresee a vast increase in the amount of data to gather, store and process. To keep the processing time bounded, parallelization and execution on (massively) parallel machines are required for the commonly-used radioastronomy software kernels. In this paper, we analyze da...
متن کاملInteractive Visualization of the Largest Radioastronomy Cubes
3D visualization is an important data analysis and knowledge discovery tool, however, interactive visualization of large 3D astronomical datasets poses a challenge for many existing data visualization packages. We present a solution to interactively visualize larger-than-memory 3D astronomical data cubes by utilizing a heterogeneous cluster of CPUs and GPUs. The system partitions the data volum...
متن کاملA C-band broadband ortho-mode transducer for radioastronomy polarimetry
BACKGROUND We describe the design, the construction and performance of a narrow band ortho-mode transducer, currently used in the 5 GHz polarimetric receiver of the Galactic Emission Mapping project. RESULTS The ortho-mode transducer was designed to achieve a high degree of transmission within the 400 MHz of the GEM band around the 5 GHz (4.8-5.2 GHz). It is composed of a circular-to-square w...
متن کاملThe Current Status of RFI Mitigation in Radioastronomy
Over the past ten years the reviews of this topic have been increasingly positive, since a variety of techniques have been shown to be viable. In a number of cases the work has advanced to the point of successful field trials. However, the take-up has been modest. Few observatories offer on-line, real-time rfi mitigation. This paper provides a brief summary of the nature and status of different...
