Chandra centres for COSMOS X-ray galaxy groups: Differences in stellar properties between central dominant and offset brightest group galaxies
Ghassem Gozaliasl, Alexis Finoguenov, Masayuki Tanaka +24
We present the results of a search for galaxy clusters and groups in the square degree of the COSMOS field using all available X-ray observations from the XMM-Newton and Ch…
Exploiting the Space Filling Curve Ordering of Particles in the Neighbour Search of Gadget3
Antonio Ragagnin, Nikola Tchipev, Michael Bader +2
Gadget3 is nowadays one of the most frequently used high performing parallel codes for cosmological hydrodynamical simulations. Recent analyses have shown t\ hat the Neighbour Sear…
Dependency of halo concentration on mass, redshift and fossilness in Magneticum hydrodynamic simulations
Antonio Ragagnin, Klaus Dolag, Lauro Moscardini +2
We study the dependency of the concentration on mass and redshift using three large N-body cosmological hydrodynamic simulations carried out by the Magneticum project. We constrain…
Gone after one orbit: How cluster environments quench galaxies
Marcel Lotz, Rhea-Silvia Remus, Klaus Dolag +2
The effect of galactic orbits on a galaxy's internal evolution within a galaxy cluster environment has been the focus of heated debate in recent years. To understand this connectio…
Athena X-IFU synthetic observations of galaxy clusters to probe the chemical enrichment of the Universe
E. Cucchetti, E. Pointecouteau, P. Peille +14
Answers to the metal production of the Universe can be found in galaxy clusters, notably within their Intra-Cluster Medium (ICM). The X-ray Integral Field Unit (X-IFU) on board the…
The Three Hundred project: a large catalogue of theoretically modelled galaxy clusters for cosmological and astrophysical applications
Weiguang Cui, Alexander Knebe, Gustavo Yepes +34
We introduce the THE THREE HUNDRED project, an endeavour to model 324 large galaxy clusters with full-physics hydrodynamical re-simulations. Here we present the data set and study…
