“…Similar results drawn from smaller samples of clusters spreading over a wider range of redshifts derived by SPT (Andersson et al 2011) and ACT (Marriage et al 2011) also agree with the Planck findings. It is, however, important to test the effects of clumping or assumptions of hydrostatic equilibrium by comparing to observations that are not related to the ICM.…”

Scaling Relations for Galaxy Clusters: Properties and Evolution

et al. 2013

Well-calibrated scaling relations between the observable properties and the total masses of clusters of galaxies are important for understanding the physical processes that give rise to these relations. They are also a critical ingredient for studies that aim to constrain cosmological parameters using galaxy clusters. For this reason much effort has been spent during the last decade to better understand and interpret relations of the properties of the intra-cluster medium. Improved X-ray data have expanded the mass range down to galaxy groups, whereas SZ surveys have openened a new observational window on the intracluster medium. In addition, continued progress in the performance of cosmological simulations has allowed a better understanding of the physical processes and selection effects affecting the observed scaling relations. Here we review the recent literature on various scaling relations, focussing on the latest observational measurements and the progress in our understanding of the deviations from self similarity.

“…Unfortunately, achieving sufficient sensitivity to detect low mass clusters in SZ is technologically very challenging. For instance, the current SPT, ACT, and Planck surveys are expected to be complete at all redshifts above mass thresholds of 7 × 10 14 M ⊙ , 10 15 M ⊙ , and 2 × 10 15 M ⊙ respectively (Vanderlinde et al, 2010;Marriage et al, 2011;Planck Collaboration et al, 2011a); while these limits will go down, they will not reach thresholds comparable to those of X-ray or optical cluster selection. Consequently, while these experiments are currently the best avenue to probe the z ≈ 1 massive cluster population, on a 3 − 5 year time scale the focus of cluster detection is likely to shift towards optical and X-ray.…”

“…The first three successful cluster SZ surveys -using the South Pole Telescope (SPT), the Atacama Cosmology Telescope (ACT), and the Planck satellite -are all currently ongoing. All three projects have released SZ-selected cluster samples (Vanderlinde et al, 2010;Marriage et al, 2011;Planck Collaboration et al, 2011a;Williamson et al, 2011;Reichardt et al, 2013). These samples tend to be of very massive clusters (see Figure 27) and, in the case of ACT and SPT, extend to z ≈ 2, with the upper limit set by the lack of massive galaxy clusters above this redshift.…”

Observational probes of cosmic acceleration

et al. 2013

The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by some form of "dark energy" with exotic physical properties, or that Einstein's theory of gravity breaks down on cosmological scales. The profound implications of cosmic acceleration have inspired ambitious efforts to understand its origin, with experiments that aim to measure the history of expansion and growth of structure with percent-level precision or higher. We review in detail the four most well established methods for making such measurements: Type Ia supernovae, baryon acoustic oscillations (BAO), weak gravitational lensing, and the abundance of galaxy clusters. We pay particular attention to the systematic uncertainties in these techniques and to strategies for controlling them at the level needed to exploit "Stage IV" dark energy facilities such as BigBOSS, LSST, Euclid, and WFIRST. We briefly review a number of other approaches including redshift-space distortions, the Alcock-Paczynski effect, and direct measurements of the Hubble constant H 0 . We present extensive forecasts for constraints on the dark energy equation of state and parameterized deviations from General Relativity, achievable with Stage III and Stage IV experimental programs that incorporate supernovae, BAO, weak lensing, and cosmic microwave background data. We also show the level of precision required for clusters or other methods to provide constraints competitive with those of these fiducial programs. We emphasize the value of a balanced program that employs several of the most powerful methods in combination, both to cross-check systematic uncertainties and to take advantage of complementary information. Surveys to probe cosmic acceleration produce data sets that support a wide range of scientific investigations, and they continue the longstanding astronomical tradition of mapping the universe in ever greater detail over ever larger scales.

“…For this, data from optical and X-ray cluster surveys are currently used to constrain cosmological parameters. Recently, however, a new window of information regarding galaxy cluster physics has opened with the release of cluster surveys (e.g., Staniszewski et al 2009;Marriage et al 2011;Williamson et al 2011;Planck Collaboration VIII 2011;Reichardt et al 2013) that make use of the SZ effect, which is a signature that does not diminish with luminosity distance because it is nearly independent of redshift. In fact, thermal SZ signal is a tracer of the total thermal energy of the hot (∼10 7 K) intracluster gas, therefore it is correlated to the mass of the cluster.…”

Aims. The cosmic distance-duality relation, d L (z)/d A (z)(1 + z) 2 = η, where d L (z) and d A (z) are, respectively, the luminosity and the angular diameter distances and where η = 1 holds as long as the number of photons is conserved and gravity is described by a metric theory. Testing such hypotheses is, therefore, an important task for both cosmology and fundamental physics. Methods. We estimated the gas mass fraction of 91 galaxy clusters (GC) from current measurements of the GC total mass recently reported by the Atacama Cosmology Telescope collaboration. We use these data, along with type Ia supernovae observations of the Union 2.1 compilation, to test a possible deviation from the value η = 1. Results. Although they agree with the standard hypothesis, we find that this combination of both data tends to favor values of η less than 1, which might be associated with some physical processes that increase the number of photons and modifying the above relation to d L < (1 + z) 2 d A .
