Are there cool-core clusters at high-redshift? Chandra results and prospects with WFXT
Joana S. Santos, Paolo Tozzi, Piero Rosati
In this contribution we trace the evolution of cool-core clusters out to z~1.3 using high-resolution Chandra data of three representative cluster samples spanning different redshif…
Proceedings of the "Wide Field X-ray Telescope" workshop
Piero Rosati, Stefano Borgani, Roberto Gilli +2
We list here the contents of the Proceedings of the "Wide Field X-ray Telescope" conference held in Bologna, Italy on 25-26 Nov 2009. The conference highlighted the scientific pote…
Wide Field X-ray Telescope: Mission Overview
P. Rosati, S. Borgani, R. Gilli +9
The Wide Field X-Ray Telescope (WFXT) is a medium-class mission designed to be 2-orders-of-magnitude more sensitive than any previous or planned X-ray mission for large area survey…
Astrophysics and cosmology with galaxy clusters: the WFXT perspective
S. Borgani, P. Rosati, B. Sartoris +2
We discuss the central role played by the X-ray study of hot baryons within galaxy clusters to reconstruct the assembly of cosmic structures and to trace the past history of star f…
Simulating the WFXT sky
P. Tozzi, J. Santos, H. Yu +9
We investigate the scientific impact of the Wide Field X-ray Telescope mission. We present simulated images and spectra of X-ray sources as observed from the three surveys planned…
The Hubble Space Telescope Cluster Supernova Survey: II. The Type Ia Supernova Rate in High-Redshift Galaxy Clusters
K. Barbary, G. Aldering, R. Amanullah +40
We report a measurement of the Type Ia supernova (SN Ia) rate in galaxy clusters at 0.9 < z < 1.45 from the Hubble Space Telescope (HST) Cluster Supernova Survey. This is the first…
