“…These multi-wavelength observations indicate that RX J1347.5−1145 is a massive (>10 15 M ) cluster at redshift z = 0.4510 which has recently undergone a merger with a smaller object. The cluster's SZ signal has been measured using single-dish (Pointecouteau et al 1999;Komatsu et al 2001;Kitayama et al 2004;Mason et al 2010;Korngut et al 2011) and interferometric (Carlstrom et al 2002;Bonamente et al 2008Bonamente et al , 2011 imaging instruments, and its spectrum near the thermal SZ null has also been characterized (Zemcov et al 2012). The higher angular resolution measurements have revealed a compact region of very hot (∼20 keV) gas to the southeast of the X-ray emission peak, while the low-resolution data indicate a lower-amplitude arcminute-scale SZ signal than suggested by a spherical fit to the X-ray data.…”

We demonstrate the Sunyaev-Zel'dovich (SZ) effect imaging capabilities of the Combined Array for Research in Millimeter-wave Astronomy (CARMA) by presenting an SZ map of the galaxy cluster RX J1347.5−1145. By combining data from multiple CARMA bands and configurations, we are able to capture the structure of this cluster over a wide range of angular scales, from its bulk properties to its core morphology. We find that roughly 9% of this cluster's thermal energy is associated with sub-arcminute-scale structure imparted by a merger, illustrating the value of high-resolution SZ measurements for pursuing cluster astrophysics and for understanding the scatter in SZ scaling relations. We also find that the cluster's SZ signal is lower in amplitude than suggested by a spherically symmetric model derived from X-ray data, consistent with compression along the line of sight relative to the plane of the sky. Finally, we discuss the impact of upgrades currently in progress that will further enhance CARMA's power as an SZ imaging instrument.

“…Given that this relation, and the underlying pressure profile, are key ingredients for the use of on-going or future SZ cluster surveys for cosmology, and provide invaluable information on the physics of the intra-cluster medium (ICM), it is important to calibrate these quantities from observations. In recent years, SZ observational capability has made spectacular progress, from the first spatially resolved (single-dish) observations of individual objects (Pointecouteau et al 1999(Pointecouteau et al , 2001Komatsu et al 1999Komatsu et al , 2001) to the first discovery of new clusters with a blind SZ survey (Staniszewski et al 2009). Spatially resolved SZE observations directly probe the mass A&A 517, A92 (2010) weighted temperature along the line of sight.…”

We investigate the regularity of cluster pressure profiles with REXCESS, a representative sample of 33 local (z < 0.2) clusters drawn from the REFLEX catalogue and observed with XMM-Newton. The sample spans a mass range of 10 14 M < M 500 < 10 15 M , where M 500 is the mass corresponding to a density contrast of 500. We derive an average profile from observations scaled by mass and redshift according to the standard self-similar model, and find that the dispersion about the mean is remarkably low, at less than 30 per cent beyond 0.2 R 500 , but increases towards the center. Deviations about the mean are related to both the mass and the thermo-dynamical state of the cluster. Morphologically disturbed systems have systematically shallower profiles while cooling core systems are more concentrated. The scaled profiles exhibit a residual mass dependence with a slope of ∼0.12, consistent with that expected from the empirically-derived slope of the M 500 − Y X relation; however, the departure from standard scaling decreases with radius and is consistent with zero at R 500 . The scatter in the core and departure from self-similar mass scaling is smaller compared to that of the entropy profiles, showing that the pressure is the quantity least affected by dynamical history and non-gravitational physics. Comparison with scaled data from several state of the art numerical simulations shows good agreement outside the core. Combining the observational data in the radial range [0.03−1] R 500 with simulation data in the radial range [1−4] R 500 , we derive a robust measure of the universal pressure profile, that, in an analytical form, defines the physical pressure profile of clusters as a function of mass and redshift up to the cluster "boundary". Using this profile and direct spherical integration of the observed pressure profiles, we estimate the integrated Compton parameter Y and investigate its scaling with M 500 and L X , the soft band X-ray luminosity. We consider both the spherically integrated quantity, Y sph (R), proportional to the gas thermal energy, and the cylindrically integrated quantity,A , which is directly related to the Sunyaev-Zel'dovich (SZ) effect signal. From the low scatter of the observed Y sph (R 500 )−Y X relation we show that variations in pressure profile shape do not introduce extra scatter into the Y sph (R 500 )− M 500 relation as compared to that from the Y X − M 500 relation. The Y sph (R 500 )− M 500 and Y sph (R 500 )−L X relations derived from the data are in excellent agreement with those expected from the universal profile. This profile is used to derive the expected Y SZ − M 500 and Y SZ − L X relations for any aperture.

“…In a few short years, SZ observations have progressed from the first spatially resolved observations of individual objects (Pointecouteau et al 1999(Pointecouteau et al , 2001Komatsu et al 1999Komatsu et al , 2001, to the first discoveries of new objects (Staniszewski et al 2009), to large-scale survey projects for cosmology such as the Atacama Cosmology Telescope (ACT, Kosowsky 2003) and the South Pole Telescope (SPT, Carlstrom et al 2011). Indeed, first cosmological results from these surveys have started appearing (Vanderlinde et al 2010;Sehgal et al 2011).…”

We present precise Sunyaev-Zeldovich (SZ) effect measurements in the direction of 62 nearby galaxy clusters (z < 0.5) detected at high signal-tonoise in the first Planck all-sky data set. The sample spans approximately a decade in total mass, 2 × 10 14 M < M 500 < 2 × 10 15 M , where M 500 is the mass corresponding to a total density contrast of 500. Combining these high quality Planck measurements with deep XMM-Newton X-ray data, we investigate the relations between D 2 A Y 500 , the integrated Compton parameter due to the SZ effect, and the X-ray-derived gas mass M g,500 , temperature T X , luminosity L X,500 , SZ signal analogue Y X,500 = M g,500 × T X , and total mass M 500 . After correction for the effect of selection bias on the scaling relations, we find results that are in excellent agreement with both X-ray predictions and recently-published ground-based data derived from smaller samples. The present data yield an exceptionally robust, high-quality local reference, and illustrate Planck's unique capabilities for all-sky statistical studies of galaxy clusters.
