Thermal Sunyaev–Zel’dovich Effect in the Circumgalactic Medium. I. Detection, and a Surprising Pattern in Self-similarity and Baryon Sufficiency

We report on the measurement of the thermal Sunyaev–Zel’dovich (tSZ) effect in the circumgalactic medium (CGM) of 641,923 galaxies with M _⋆ = 10 ^9.8–11.3 M _⊙ at z < 0.5, pushing the exploration of the tSZ effect to lower-mass galaxies compared to those in previous studies. We cross-correlate the...
