High-resolution SZ imaging of clusters of galaxies with the NIKA2 camera at the IRAM 30-m telescope

Understand

The development of precision cosmology with clusters of galaxies requires high-angular resolution Sunyaev-Zel'dovich (SZ) observations.

• As for now, arcmin resolution SZ observations (e.g.
• SPT, ACT and Planck) only allowed detailed studies of the intra cluster medium for low redshift clusters (z<0.2).
• With both a wide field of view (6.5 arcmin) and a high angular resolution (17.7 and 11.2 arcsec at 150 and 260 GHz), the NIKA2 camera installed at the IRAM 30-m telescope (Pico Veleta, Spain), will bring valuable information in the field of SZ imaging of clusters of galaxies.
