Identification of galaxy cluster substructures with the Caustic method
Heng Yu, Ana Laura Serra, Antonaldo Diaferio +1
We investigate the power of the caustic technique for identifying substructures of galaxy clusters from optical redshift data alone. The caustic technique is designed to estimate t…
Disentangling dark sector models using weak lensing statistics
Carlo Giocoli, R. Benton Metcalf, Marco Baldi +3
We perform multi-plane ray-tracing using the GLAMER gravitational lensing code within high-resolution light-cones extracted from the CoDECS simulations: a suite of cosmological run…
The mass accretion rate of galaxy clusters: a measurable quantity
Cristiano De Boni, Ana Laura Serra, Antonaldo Diaferio +2
We explore the possibility of measuring the mass accretion rate (MAR) of galaxy clusters from their mass profiles beyond the virial radius . We derive the accretion rate f…
