Average X-ray properties of galaxy groups. From Milky Way-like halos to massive clusters
P. Popesso, I. Marini, K. Dolag +20
This study examines the average X-ray properties of massive halos at z< 0.2, covering the largest halo mass range to date, from Milky Way-like halos to massive clusters. The analys…
The hot gas mass fraction in halos. From Milky Way-like groups to massive clusters
P. Popesso, A. Biviano, I. Marini +21
By using eROSITA data in the eFEDS area, we provide a measure of the hot gas fraction vs. halo mass relation over the largest halo mass range, from Milky Way-sized halos to massive…
The perils of stacking optically selected groups in eROSITA data. The Magneticum perspective
P. Popesso, I. Marini, K. Dolag +23
Hydrodynamical simulation predictions are often compared with observational data without fully accounting for systematics and biases specific to observational techniques. Using the…
On the redshift evolution of the baryon and gas fraction in simulated groups and clusters of galaxies
M. Angelinelli, S. Ettori, K. Dolag +2
We study the redshift evolution of the baryon budget in a large set of galaxy clusters from the {\it Magneticum} suite of SPH cosmological simulations. At high redshifts, we obtain…
The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase
Didier Barret, Vincent Albouys, Jan-Willem den Herder +296
The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile ob…
Mapping "out-of-the-box" the properties of the baryons in massive halos
M. Angelinelli, S. Ettori, K. Dolag +2
We study the distributions of the baryons in massive halos () in the suite of Smoothed Particle Hydrodynamical cosmological simula…
Magnetogenesis and the Cosmic Web: a joint challenge for radio observations and numerical simulations
Franco Vazza, Nicola Locatelli, Kamlesh Rajpurohit +16
The detection of the radio signal from filaments in the cosmic web is crucial to distinguish possible magnetogenesis scenarios. We review the status of the different attempts to de…
Properties of clumps and filaments around galaxy clusters
M. Angelinelli, S. Ettori, F. Vazza +1
We report on the possibility of studying the proprieties of cosmic diffuse baryons by studying self-gravitating clumps and filaments connected to galaxy clusters. While filaments a…
Turbulent pressure support and hydrostatic mass-bias in the intracluster medium
M. Angelinelli, F. Vazza, C. Giocoli +5
The degree of turbulent pressure support by residual gas motions in galaxy clusters is not well known. Mass modelling of combined X-ray and Sunyaev Zel'dovich observations provides…
Detecting shocked intergalactic gas with X-ray and radio observations
F. Vazza, S. Ettori, M. Roncarelli +3
Detecting the thermal and non-thermal emission from the shocked cosmic gas surrounding large-scale structures represents a challenge for observations, as well as a unique window in…
The turbulent pressure support in galaxy clusters revisited
F. Vazza, M. Angelinelli, T. W. Jones +4
Due to their late formation in cosmic history, clusters of galaxies are not fully in hydrostatic equilibrium and the gravitational pull of their mass at a given radius is expected…
