We use combined South Pole Telescope (SPT)+Planck temperature maps to analyzethe circumgalactic medium (CGM) encompassing 138,235 massive, quiescent 0.5$\leq$ z $\leq$ 1.5 galaxies selected from data from the Dark Energy Survey(DES) and Wide-Field Infrared Survey Explorer (WISE). Images centered on thesegalaxies were cut from the 1.85 arcmin resolution maps with frequency bands at95, 150, and 220 GHz. The images were stacked, filtered, and fit with agray-body dust model to isolate the thermal Sunyaev-Zel'dovich (tSZ) signal,which is proportional to the total energy contained in the CGM of the galaxies.We separate these $M_{\star} = 10^{10.9} M_\odot$ - $10^{12} M_\odot$ galaxiesinto 0.1 dex stellar mass bins, detecting tSZ per bin up to $5.6\sigma$ and atotal signal-to-noise ratio of $10.1\sigma$. We also detect dust with anoverall signal-to-noise ratio of $9.8\sigma$, which overwhelms the tSZ at150GHz more than in other lower-redshift studies. We correct for the $0.16$ dexuncertainty in the stellar mass measurements by parameter fitting for anunconvolved power-law energy-mass relation, $E_{\rm therm} = E_{\rm therm,peak}\left(M_\star/M_{\star,{\rm peak}} \right)^\alpha$, with the peak stellar massdistribution of our selected galaxies defined as $M_{\star,{\rm peak}}= 2.3\times 10^{11} M_\odot$. This yields an $E_{\rm therm,peak}=5.98_{-1.00}^{+1.02} \times 10^{60}$ erg and $\alpha=3.77_{-0.74}^{+0.60}$.These are consistent with $z \approx 0$ observations and within the limits ofmoderate models of active galactic nuclei (AGN) feedback. We also compute theradial profile of our full sample, which is similar to that recently measuredat lower-redshift by Schaan et al. (2021).
