Title: Gas contents in the low-z Universe
Description: We used both the thermal and kinetc Sunyaev-Zel'dovich effect (tSZE and kSZE, respectively) to estimate SZE flux from gas in halos, as well as to estimate the thermal energy of IGM gas in regions of different total matter density. As observational data, we used the Planck CMB temperature map, all-sky group catalog of Lim et al. 2017b, and reconstruction of the large-scale structure such as density field, tidal field, and velocity field based on the group catalog. As for the method, we employed the matched filter (MF) technique to maximize the detection. In particular, we did the MF simultaneously for all groups to take into account projections of nearby halos, which is predicted to be significant. Indeed, we show, using SZE lightcone maps constructed from simulations, that only the simultaneous MF can successfully recover the true SZE flux from the simulations, while the traditional MF and aperture photometry over-estimate the flux. Comparing simulations of different feedback models including EAGLE, Illustris, and IllustrisTNG, we also show that our results about IGM gas can constrain galaxy models.
