Mapping the intracluster medium temperature in the era of NIKA2 and
  MUSTANG-2
  We present preliminary results from an on-going program that aims at mapping
the intracluster medium (ICM) temperature of high redshift galaxy clusters from
the MaDCoWS sample using a joint analysis of shallow X-ray data obtained by
$Chandra$ and high angular resolution Sunyaev-Zel'dovich (SZ) observations
realized with the NIKA2 and MUSTANG-2 cameras. We also present preliminary
results from an on-going Open Time program within the NIKA2 collaboration that
aims at mapping the ICM temperature of a galaxy cluster at $z=0.45$ from the
resolved detection of the relativistic corrections to the SZ spectrum. These
studies demonstrate how high angular resolution SZ observations will play a
major role in the coming decade to push the investigation of ICM dynamics and
non-gravitational processes to high redshift before the next generation X-ray
observatories come into play.
