In this talk we present an update of the HPC Bluebild algorithm developed at EPFL, BIPP. We give a short overview of the algorithm and present some new science use cases that are being examined in the group.
The growth of radio astronomy data rates challenges current data processing techniques. With the Square Kilometer Array (SKA) expected to produce exabytes of data every year, many more radio sources can be expected to be discovered at higher redshift and better resolution. Due to storage difficulties, analysis of this data will need to be done without manual manipulation of visibilities. An...
Radio Frequency Interference (RFI) is a growing problem in radio astronomy. As of October 2024, more than 13,000 satellites are orbiting Earth, with the number steadily increasing due to the deployment of large-scale satellite constellations such as Starlink. Methods to address RFI are therefore essential. In novel work we have successfully performed trajectory based RFI subtraction on real...
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) radio interferometer array aims to observe neutral hydrogen (HI) through intensity mapping (IM) in the redshift range of 0.775-2.55. It is currently being built at the South African Radio Astronomy Observatory (SARAO) Square Kilometer Array (SKA) site in South Africa. HI IM makes it possible to tomographically probe large,...
