Abstract (from CDS):

The galaxy cluster Zwicky 3146 is a sloshing cool core cluster at z = 0.291 that in X-ray imaging does not appear to exhibit significant pressure substructure in the intracluster medium (ICM). The published M500 values range between 3.88–0.58+0.62 to (22.50 ± 7.58) x 1014 M, where ICM-based estimates with reported errors <20% suggest that we should expect to find a mass between 6.53–0.44+0.44×1014M (from Planck, with an 8.4σ detection) and 8.52–1.47+1.77×1014M (from ACT, with a 14σ detection). We investigate the ability to estimate the mass of Zwicky 3146 via the Sunyaev-Zel'dovich (SZ) effect with data taken at 90 GHz by MUSTANG-2 to a noise level better than 15 µK at the center and a cluster detection of 61σ. We derive a pressure profile from our SZ data, which is in excellent agreement with that derived from X-ray data. From our SZ-derived pressure profiles, we infer M500 and M2500 via three methods-Y-M scaling relations, the virial theorem, and hydrostatic equilibrium (HE)-where we employ X-ray constraints from XMM-Newton on the electron density profile when assuming HE. Depending on the model and estimation method, our M500 estimates range from 6.13 ± 0.69 to (10.6 ± 2.0) x 1014 M, where our estimate from HE is 7.69–1.98+2.19 (±27% stat)–0.59+0.63 (±7.9% sys, calibration) x 1014 M. Our fiducial mass, derived from a Y-M relation is 8.06–0.61+0.67 (±7.9% stat)–0.42+0.45 (±5.4% sys, Y-M)–0.54+0.58 (±6.9% sys, cal.) x 1014 M.
