Our bonanza week of talks was finished up of Friday afternoon with Kavilan Moodley giving us a brief overview of the recent measurement of the kinematic Sunyaev-Zel’dovch effect using a combination of ACT and BOSS data, described in 1203.4219.
Kavilan first explained that the kSZ effect arises from the effect of the peculiar velocities of galaxies on the temperature of CMB photons. He then went through some of the difficulties associated with extracting a measurement given all the other effects on the measured CMB temperature and reviewed the particular statistic used by the collaboration.
The measurement of kSZ effect is at the cutting edge of observational cosmology, and offers great possibilities for rich data in the future. Thanks very much to Kavilan for giving us an overview of the paper practically hot off the presses!
