The thermal and kinematic Sunyaev-Zel'dovich effects (tSZ, kSZ) probe thethermodynamic properties of the circumgalactic and intracluster medium (CGM andICM) of galaxies, groups, and clusters, since they are proportional,respectively, to the integrated electron pressure and momentum along theline-of-sight. We present constraints on the gas thermodynamics of CMASSgalaxies in the Baryon Oscillation Spectroscopic Survey (BOSS) using newmeasurements of the kSZ and tSZ signals obtained in a companion paper.Combining kSZ and tSZ measurements, we measure within our model the amplitudeof energy injection $\epsilon M_\star c^2$, where $M_\star$ is the stellarmass, to be $\epsilon=(40\pm9)\times10^{-6}$, and the amplitude of thenon-thermal pressure profile to be $\alpha_{\rm Nth}<0.2$ (2$\sigma$),indicating that less than 20% of the total pressure within the virial radius isdue to a non-thermal component. We estimate the effects of including baryons inthe modeling of weak-lensing galaxy cross-correlation measurements using thebest-fit density profile from the kSZ measurement. Our estimate reduces thedifference between the original theoretical model and the weak-lensing galaxycross-correlation measurements in arXiv:1611.08606 by half but does not fullyreconcile it. Comparing the tSZ measurements to cosmological simulations, wefind that simulations underestimate the CGM pressure at large radii while theyfare better in comparison with the kSZ measurements. This suggests that theenergy injected via feedback models in the simulations that we compared againstdoes not sufficiently heat the gas at these radii. We do not find significantdisagreement at smaller radii. These measurements provide novel tests ofcurrent and future simulations. This work demonstrates the power of joint, highsignal-to-noise kSZ and tSZ observations, upon which future cross-correlationstudies will improve.
