MARS: A Lightweight Morphology-Aware RFI Segmentation Network for Mask-Guided Mitigation in Radio Astronomy
Zhaocheng Gong, Jack White, Jayanta Roy +1
Next-generation radio telescopes generate filterbank data at rates that make storing all observations for later offline mitigation impractical. Mitigation must therefore operate in…
FIP-TOI: Fast Imaging Pipeline for Pulsar Localisation with a Transient-Oriented Radio Astronomical Imager
X. Li, K. Adamek, M. Giles +3
Rapid localisation of radio transients requires imaging pipelines that combine low latency, high sensitivity, and accurate transient positioning. Fast Imaging Pipeline (FIP) define…
Globular Clusters GMRT Pulsar Search (GCGPS) I: Survey description, discovery and timing of the first pulsar in NGC 6093 (M80)
Jyotirmoy Das, Jayanta Roy, Paulo C. C. Freire +6
This paper describes the new Globular Clusters GMRT Pulsar Search (GCGPS) survey. This survey aims to find MSPs in the globular clusters (GCs) of the Milky Way using uGMRT. The obs…
Distribution of the Högbom CLEAN Algorithm Using Tiled Images with Feedback
Daniel Wright, Karel Adámek, Wesley Armour
Data sizes for next generation radio telescopes, such as the Square Kilometre Array (SKA), are far above that of their predecessors. The CLEAN algorithm was originally developed by…
Lowering In-Memory Footprint of Antenna Beams via Polynomial Approximation
Ali Taqi, Karel Adámek, Quentin Gueuning +3
With the emergence of new radio telescopes promising larger fields of view at lower observation frequencies (e.g., SKA), addressing direction-dependent effects (DDE) (e.g., directi…
