Matter power spectra in dynamical-Dark Energy cosmologies
C. Fedeli, K. Dolag, L. Moscardini
(abridged) We used a suite of numerical cosmological simulations in order to investigate the effect of gas cooling and star formation on the large scale matter distribution. The si…
Observing the clustering properties of galaxy clusters in dynamical dark-energy cosmologies
C. Fedeli, L. Moscardini, M. Bartelmann
We study the clustering properties of galaxy clusters expected to be observed by various forthcoming surveys both in the X-ray and sub-mm regimes by the thermal Sunyaev-Zel'dovich…
Asymmetric Gravitational Lenses in TeVeS and Application to the Bullet Cluster
M. Feix, C. Fedeli, M. Bartelmann
Aims: We explore the lensing properties of asymmetric matter density distributions in Bekenstein's Tensor-Vector-Scalar theory (TeVeS). Methods: Using an iterative Fourier-based so…
Next Generation Cosmology: Constraints from the Euclid Galaxy Cluster Survey
B. Sartoris, A. Biviano, C. Fedeli +10
We study the characteristics of the galaxy cluster samples expected from the European Space Agency's Euclid satellite and forecast constraints on cosmological parameters describing…
Comparison of an X-ray selected sample of massive lensing clusters with the MareNostrum Universe LCDM simulation
M. Meneghetti, C. Fedeli, A. Zitrin +5
A long-standing problem of strong lensing by galaxy clusters regards the observed high rate of giant gravitational arcs as compared to the predictions in the framework of the "stan…
On the abundance of gravitational arcs produced by submillimeter galaxies at radio and submm wavelengths
C. Fedeli, A. Berciano Alba
We predict the abundance of giant gravitational arcs produced by submillimeter galaxies (SMGs) lensed by foreground galaxy clusters, both at radio and submm wavelengths. The galaxy…
