Dianoga simulations of galaxy clusters and groups: Properties of the baryonic components
Stefano Borgani, Alice Damiano, Elena Rasia +12
We introduce the Dianoga set of cosmological simulations of galaxy clusters and groups, specifically aimed at studying the impact of the implementation of AGN feedback and star for…
OpenGadget3 GPU solver tests
A. Ragagnin, G. S. Karademir, F. Groth +6
We present an in-depth evaluation of the scalability and accuracy of the GPU porting of the N-body code for hydrodynamic cosmological simulations \og. While technical details of ou…
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…
Accelerating cosmological simulations on GPUs: a step towards sustainability and green-awareness
Giovanni Lacopo, Marius Daniel Lepinzan, David Goz +7
The increasing complexity and scale of cosmological N-body simulations, driven by astronomical surveys like Euclid, call for a paradigm shift towards more sustainable and energy-ef…
EuroHPC SPACE CoE: Redesigning Scalable Parallel Astrophysical Codes for Exascale
Nitin Shukla, Alessandro Romeo, Caterina Caravita +36
High Performance Computing (HPC) based simulations are crucial in Astrophysics and Cosmology (A&C), helping scientists investigate and understand complex astrophysical phenomena. T…
High [OI] emission lines: ColdSIM simulations and ALMA observations
Massimiliano Parente, Manuela Bischetti, Umberto Maio +8
Neutral-oxygen [OI] far-infrared emission lines at m and m are powerful probes of the physical conditions in the interstellar medium, although they have not been fully…
