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…
Infall Regions and Scaling Relations of X-ray Selected Groups
Kenneth Rines, Antonaldo Diaferio
We use the Fifth Data Release of the Sloan Digital Sky Survey to study X-ray-selected galaxy groups and compare their properties to clusters. We search for infall patterns around t…
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…
How the Scalar Field of Unified Dark Matter Models Can Cluster
Daniele Bertacca, Nicola Bartolo, Antonaldo Diaferio +1
We use scalar-field Lagrangians with a non-canonical kinetic term to obtain unified dark matter models where both the dark matter and the dark energy, the latter mimicking a cosmol…
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…
