Deep learning approach for identification of HII regions during reionization in 21-cm observations -- III. image recovery
Michele Bianco, Sambit. K. Giri, Rohit Sharma +7
The low-frequency component of the upcoming Square Kilometre Array Observatory (SKA-Low) will be sensitive enough to construct 3D tomographic images of the 21-cm signal distributio…
Primary Beam Chromaticity in HIRAX: I. Characterization from Simulations and Power Spectrum Implications
Ajith Sampath, Devin Crichton, Kavilan Moodley +15
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is an upcoming radio interferometric telescope designed to constrain dark energy through the 21cm intensity mapping…
BIPP: An efficient HPC implementation of the Bluebild algorithm for radio astronomy
Emma Tolley, Simon Frasch, Etienne Orliac +6
The Bluebild algorithm is a new technique for image synthesis in radio astronomy which decomposes the sky into distinct energy levels using functional principal component analysis.…
Radio Halo Detection in MWA Data using Deep Neural Networks and Generative Data Augmentation
Ashutosh K. Mishra, Emma Tolley, Shreyam Parth Krishna +1
Detecting diffuse radio emission, such as from halos, in galaxy clusters is crucial for understanding large-scale structure formation in the universe. Traditional methods, which re…
