Constraining f(R) theories with Type Ia Supernovae and Gamma Ray Bursts
Vincenzo F. Cardone, Antonaldo Diaferio, Stefano Camera
Fourth - order gravity theories have received much interest in recent years thanks to their ability to provide an accelerated cosmic expansion in a matter only universe. In these t…
Measuring the mass profile of galaxy clusters beyond their virial radius
Antonaldo Diaferio
Traditional estimators of the mass of galaxy clusters assume that the cluster components (galaxies, intracluster medium, and dark matter) are in dynamical equilibrium. Two addition…
Modelling the broad-band spectra of X-ray emitting GPS galaxies
L. Ostorero, R. Moderski, L. Stawarz +5
The study of the broad-band emission of GHz-Peaked-Spectrum (GPS) radio galaxies is a powerful tool to investigate the physical processes taking place in the central, kpc-sized reg…
X-ray clusters of galaxies in conformal gravity
Antonaldo Diaferio, Luisa Ostorero
We run adiabatic N-body/hydrodynamical simulations of isolated self-gravitating gas clouds to test whether conformal gravity, an alternative theory to General Relativity, is able t…
WMAP5 and the Cluster Mass Function
Kenneth Rines, Antonaldo Diaferio, Priyamvada Natarajan
The recently revised cosmological constraints from the Five-Year WMAP data ameliorate previous tension between cosmological constraints from the microwave background and from clust…
The evidence for unusual gravity from the large-scale structure of the Universe
A. Diaferio
Under the assumption that General Relativity (GR) correctly describes the phenomenology of our Universe, astronomical observations provide compelling evidence that (1) the dynamics…
