We present analysis of a 100 ks Chandra observation of galaxy cluster MACS 1423. At a redshift of 0.54, this is the most distant massive cooling-flow cluster known. We derive azimuthally averaged, deprojected temperature, metallicity and density profiles, and find a gas mass fraction in agreement with previous work by Allen et al. (2004). The Navarro, Frenk and White (NFW) model provides an acceptable fit to the mass profile; a generalized NFW model was also explored, but did not provide a better fit. A singular isothermal sphere mass model is strongly ruled out. We also present two-dimensional maps of projected temperature, entropy and pressure which, beyond the innermost core, do not indicate any significant deviations from spherically symmetric equilibrium. Finally, we compare the mass profile derived from the X-ray data with independent weak lensing results determined from deep, multi-color Subaru SuprimeCam imaging. This work was supported by the U.S. Department of Energy under contract number DE-AC02-76SF00515.
