Accelerating radio astronomy imaging with RICK: a step towards SKA-Mid and SKA-Low
Giovanni Lacopo, Emanuele De Rubeis, Claudio Gheller +2
The data volumes generated by modern radio interferometers, such as the SKA precursors, present significant computational challenges for imaging pipelines. Addressing the need for…
Estimating Flux Densities of Diffuse Cosmological Radio Sources Exploiting Vision Transformers
Nicoletta Sanvitale, Claudio Gheller, Franco Vazza +3
We present TUNA, a Vision-Transformer based network adapted from segmentation to flux regression for faint, diffuse radio emission. Trained on LOFAR-like mock observations derived…
Mapping Diffuse Radio Sources Using TUNA: A Transformer-Based Deep Learning Approach
Nicoletta Sanvitale, Claudio Gheller, Franco Vazza +6
Vision Transformers are used via a customized TransUNet architecture, which is a hybrid model combining Transformers into a U-Net backbone, to achieve precise, automated, and fast…
Green computing toward SKA era with RICK
Giovanni Lacopo, Claudio Gheller, Emanuele De Rubeis +5
Square Kilometer Array is expected to generate hundreds of petabytes of data per year, two orders of magnitude more than current radio interferometers. Data processing at this scal…
Accelerating radio astronomy imaging with RICK
Emanuele De Rubeis, Giovanni Lacopo, Claudio Gheller +2
This paper presents an implementation of radio astronomy imaging algorithms on modern High Performance Computing (HPC) infrastructures, exploiting distributed memory parallelism an…
Radio U-Net: a convolutional neural network to detect diffuse radio sources in galaxy clusters and beyond
Chiara Stuardi, Claudio Gheller, Franco Vazza +1
The forthcoming generation of radio telescope arrays promises significant advancements in sensitivity and resolution, enabling the identification and characterization of many new f…
VisIVOWeb: A WWW Environment for Large-Scale Astrophysical Visualization
A. Costa, U. Becciani, P. Massimino +5
This article presents a newly developed Web portal called VisIVOWeb that aims to provide the astrophysical community with powerful visualization tools for large-scale data sets in…
Splotch: Visualizing Cosmological Simulations
K. Dolag, M. Reinecke, C. Gheller +1
We present a light and fast, public available, ray-tracer {\tt Splotch} software tool which supports the effective visualization of cosmological simulations data. We describe the a…
