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.…
Deep Learning Based Detection of Cosmological Diffuse Radio Sources
Claudio Gheller, Franco Vazza, Annalisa Bonafede
In this paper we introduce a reliable, fully automated and fast algorithm to detect extended extragalactic radio sources (cluster of galaxies, filaments) in existing and forthcomin…
Interactive 3D Visualization for Theoretical Virtual Observatories
Tim Dykes, Amr Hassan, Claudio Gheller +2
Virtual Observatories (VOs) are online hubs of scientific knowledge. They encompass a collection of platforms dedicated to the storage and dissemination of astronomical data, from…
DIAPHANE: a Portable Radiation Transport Library for Astrophysical Applications
Darren S. Reed, Tim Dykes, Ruben Cabezon +2
One of the most computationally demanding aspects of the hydrodynamical modelling of Astrophysical phenomena is the transport of energy by radiation or relativistic particles. Phys…
Numerical cosmology on the GPU with Enzo and Ramses
Claudio Gheller, Peng Wang, Franco Vazza +1
A number of scientific numerical codes can currently exploit GPUs with remarkable performance. In astrophysics, Enzo and Ramses are prime examples of such applications. The two cod…
GPU Accelerated Particle Visualization with Splotch
Marzia Rivi, Claudio Gheller, Tim Dykes +2
Splotch is a rendering algorithm for exploration and visual discovery in particle-based datasets coming from astronomical observations or numerical simulations. The strengths of th…
