HI Intensity Mapping (HIIM) as a probe of cosmological large-scale structures (LSS) is considered promising and has been test with cross-correlation with optical galaxy survey using Green Bank Telescope (GBT) and Parkes Telescope. MeerKAT and SKA have the potential to achieve largest and deepest HIIM survey in the near future. However, HIIM is also most challenging due to the bright foreground...
Our ability to capture and store data is increasing, so is the information we are capturing. With the petabytes of data being captured and to be captured in the future with SKA, analysing this data and extracting information from them in the traditional way will not suffice. It is inevitable, to use machine learning to understand the underlying information captured in the data. These...
The Very Large Array (VLA) and Very Long Baseline Array (VLBA) have been operated by the National Radio Astronomy Observatory for several decades now. Both instruments comprise distributed operations at some level, requiring coordination across sites, departments, divisions, and groups. We illustrate the complexity of a distributed operational model using the example of Science Operations,...
LOFAR combines signals from 51 phased array antenna stations distributed in The Netherlands and across Europe up to a maximum baseline of about 2000 kilometers. It covers the largely unexplored low-frequency range from 10-240~MHz and provides several unique observing capabilities. Every second, tens of gigabytes of data flow through a massive ICT infrastructure from the stations to the...
