Observational Evidence of Velocity Anisotropy Assembly Bias in Galaxy Clusters
Facundo Rodriguez, Andrea Biviano, Ravi K. Sheth +2
Cosmological simulations show that halo clustering depends on secondary internal properties beyond mass, an effect known as assembly bias. In particular, numerical models have show…
Linking X-ray emission to galaxy populations in GAMA groups
Selene Levis, Hernán Muriel, Valeria Coenda +3
We study how the presence of a detectable hot intragroup medium affects galaxy colour and star-formation properties, and how these trends depend on dynamical stage within the group…
Exploring the dark sector through galaxy dynamics in clusters
Andrea Biviano, Lorenzo Pizzuti, Antonaldo Diaferio
Galaxy clusters are among the most powerful laboratories to probe fundamental physics, from the formation of cosmic structures to the nature of dark matter, dark energy, and gravit…
CLASH-VLT: The Fifth Force in Chameleon Gravity from Joint Lensing and Kinematics Cluster Mass Profiles
Lorenzo Pizzuti, Federico Rivano, Keiichi Umetsu +1
We present a high-precision joint gravitational-lensing and kinematic analysis of nine massive galaxy clusters from the CLASH and CLASH-VLT surveys to test chameleon screening grav…
The search for galaxy cluster members with deep learning of panchromatic HST imaging and extensive spectroscopy
G. Angora, P. Rosati, M. Brescia +9
The next generation of data-intensive surveys are bound to produce a vast amount of data, which can be dealt with using machine-learning methods to explore possible correlations wi…
Clusters of Galaxies: Structure and Dynamics in the Last 8 Gyr
A. Biviano
Clusters of galaxies, being dark matter dominated, have long been and still are the ideal cosmological targets to study the nature of dark matter. Constraints on the nature of dark…
