Galaxy clusters in the CFHTLS. First matched filter candidate catalogue of the Deep fields
L. F. Olsen, C. Benoist, A. Cappi +6
We apply a matched-filter cluster detection algorithm to the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) i-band data for the Deep-1, Deep-2, Deep-3 and Deep-4 fields cove…
Studies of an array of PbF2 Cherenkov crystals with large-area SiPM readout
A. T. Fienberg, L. P. Alonzi, A. Anastasi +30
The electromagnetic calorimeter for the new muon (g-2) experiment at Fermilab will consist of arrays of PbF2 Cherenkov crystals read out by large-area silicon photo-multiplier (SiP…
Observations of extended radio emission in clusters
C. Ferrari, F. Govoni, S. Schindler +2
We review observations of extended regions of radio emission in clusters; these include diffuse emission in `relics', and the large central regions commonly referred to as `halos'.…
Discovery of the correspondence between intra-cluster radio emission and a high pressure region detected through the Sunyaev-Zel'dovich effect
C. Ferrari, H. T. Intema, E. Orrù +9
We analyzed new 237 MHz and 614 MHz GMRT data of the most X-ray luminous galaxy cluster, RX J1347-1145. Our radio results are compared with the MUSTANG 90 GHz Sunyaev-Zel'dovich ef…
Sub-structure and merger detection in resolved NIKA Sunyaev-Zel'dovich images of distant clusters
R. Adam, O. Hahn, F. Ruppin +48
Sub-structures in the hot gas of galaxy clusters are related to their formation history and to the astrophysical processes at play in the intracluster medium (ICM). The thermal Sun…
A2163: Merger events in the hottest Abell galaxy cluster II. Subcluster accretion with galaxy-gas separation
H. Bourdin, M. Arnaud, P. Mazzotta +7
Located at z = 0.203, A2163 is a rich galaxy cluster with an intra-cluster medium (ICM) that exhibits extraordinary properties, including an exceptionally high X-ray luminosity, av…
