Abstract
Galaxy clusters and surrounding medium, can be studied using X-ray bremsstrahlung emission and Sunyaev Zel'dovich (SZ) effect. Both astrophysical probes, sample the same environment with different parameters dependance. The SZ effect is relatively more sensitive in low density environments and thus is useful to study the filamentary structures of the cosmic web. In addition, observations of the matter distribution require high angular resolution in order to be able to map the matter distribution within and around galaxy clusters. MISTRAL is a camera working at 90GHz which, once coupled to the Sardinia Radio Telescope (SRT), can reach 12 '' angular resolution over 4' field of view (f.o.v.). The forecasted sensitivity drives to a Noise Equivalent Flux Density of similar or equal to 10- 15 mJy root s and the mapping speed is MS = 380'(2) mJy(-2) h(-1). MISTRAL was recently installed at the focus of the SRT and soon will take its first photons.| File | Dimensione | Formato | |
