Simulation view of galaxy clusters with low X-ray surface brightness
Antonio Ragagnin, Stefano Andreon, Emanuella Puddu
X-ray selected samples are known to miss galaxy clusters that are gas poor and have a low surface brightness. This is different for the optically selected samples such as the X-ray…
Velocity dispersion of the brightest cluster galaxies in cosmological simulations
I. Marini, S. Borgani, A. Saro +7
Using the DIANOGA hydrodynamical zoom-in simulation set of galaxy clusters, we analyze the dynamics traced by stars belonging to the Brightest Cluster Galaxies (BCGs) and their sur…
Thermodynamic evolution of the galaxy cluster IDCS J1426.5+3508
S. Andreon, C. Romero, F. Castagna +8
We present resolved thermodynamic profiles out to 500 kpc, about , of the galaxy cluster IDCS J1426.5+3508 with 40 kpc resolution. Thanks to the combination of Su…
The DIANOGA simulations of galaxy clusters: characterizing star formation in proto-clusters
L. Bassini, E. Rasia, S. Borgani +11
We studied the star formation rate (SFR) in cosmological hydrodynamical simulations of galaxy (proto-)clusters in the redshift range , comparing them to recent observational…
Performance and energy footprint assessment of FPGAs and GPUs on HPC systems using Astrophysics application
David Goz, Georgios Ieronymakis, Vassilis Papaefstathiou +7
New challenges in Astronomy and Astrophysics (AA) are urging the need for a large number of exceptionally computationally intensive simulations. "Exascale" (and beyond) computation…
Gadget3 on GPUs with OpenACC
Antonio Ragagnin, Klaus Dolag, Mathias Wagner +5
We present preliminary results of a GPU porting of all main Gadget3 modules (gravity computation, SPH density computation, SPH hydrodynamic force, and thermal conduction) using Ope…
