Towards a Mini-App for Smoothed Particle Hydrodynamics at Exascale
Danilo Guerrera, Rubén M. Cabezón, Jean-Guillaume Piccinali +5
The smoothed particle hydrodynamics (SPH) technique is a purely Lagrangian method, used in numerical simulations of fluids in astrophysics and computational fluid dynamics, among m…
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…
Probing the origin of extragalactic magnetic fields with Fast Radio Bursts
F. Vazza, M. Brüggen, P. M. Hinz +3
The joint analysis of the Dispersion and Faraday Rotation Measure from distant, polarised Fast Radio Bursts may be used to put constraints on the origin and distribution of extraga…
Observations of a nearby filament of galaxy clusters with the Sardinia Radio Telescope
V. Vacca, M. Murgia, F. Govoni +29
We report the detection of diffuse radio emission which might be connected to a large-scale filament of the cosmic web covering a 8deg x 8deg area in the sky, likely associated wit…
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…
Microhartree Precision in Density-Functional-Theory Calculations
Andris Gulans, Anton Kozhevnikov, Claudia Draxl
To address ultimate precision in density-functional-theory calculations we employ the full-potential linearized augmented planewave + local-orbital (LAPW+lo) method and justify its…
