Atacama Cosmology Telescope: Combined kinematic and thermal Sunyaev-Zel’dovich measurements from BOSS CMASS and LOWZ halos

The imprint left on the cosmic microwave background (CMB) from CMB photons scattering off high-energy electrons in galaxies and clusters is known as the Sunyaev-Zel'dovich (SZ) effect and is the subject of these two papers from the Atacama Cosmology Telescope (ACT). ACT measurements combined with those of Planck and BOSS are shown to provide a rich picture of the electron gas thermodynamics of the galactic and cluster medium. This can be used to test and improve cosmological simulations relevant for upcoming experiments.
