Description
To date, image plane transients found in LOFAR observations are found weeks to months after the observation took place. This significantly hinders obtaining multi-wavelength follow-up observations that are vital in determining the progenitor of the transient and characterising its properties. Instead, we want to be able to find the brightest transient sources, particularly the long period Galactic transients, in near real-time. In the coming 2 years, LOFAR is undergoing a significant upgrade and will also have the data streamed in real-time to the EuroFlash cluster (PI: Jason Hessels). This project tests, develops and implements a very fast imaging strategy on the EuroFlash cluster that bypasses the very time consuming calibration steps. This involves producing difference images and developing an automated strategy to deal with discerning detections and false positives. Using existing observations of the LOFAR long period Galactic source ILT J1101+5521 (de Ruiter 2024) and other LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) data, this project shows the potential of this new method.
