“…ACT is a 6 m off-axis Gregorian telescope (Fowler et al 2007) situated at an elevation of 5190 m on Cerro Toco in the Atacama desert in northern Chile. ACT has three frequency bands centered at 148 GHz (2.0 mm), 218 GHz (1.4 mm), and 277 GHz (1.1 mm) with angular resolutions of roughly 1.…”

“…We use mm-wave data from the Atacama Cosmology Telescope (ACT; Fowler et al 2007;Swetz et al 2010) at 1380 and 2030 μm (218 and 148 GHz), collected during the 2008 observing season, and submm wave data from the Balloon-borne Large Aperture Submillimeter Telescope (BLAST; Pascale et al 2008;Devlin et al 2009) at 250, 350, and 500 μm (1200, 860, and 600 GHz), which were collected during its 11 day flight, at ∼40 km altitude, in Antarctica in 2006. We use these to measure the power from DSFGs, both Poisson and clustered.…”

We present measurements of the auto-and cross-frequency correlation power spectra of the cosmic (sub)millimeter background at 250, 350, and 500 μm (1200, 860, and 600 GHz) from observations made with the Balloonborne Large Aperture Submillimeter Telescope (BLAST); and at 1380 and 2030 μm (218 and 148 GHz) from observations made with the Atacama Cosmology Telescope (ACT). The overlapping observations cover 8.6 deg 2 in an area relatively free of Galactic dust near the south ecliptic pole. The ACT bands are sensitive to radiation from the cosmic microwave background, to the Sunyaev-Zel'dovich effect from galaxy clusters, and to emission by radio and dusty star-forming galaxies (DSFGs), while the dominant contribution to the BLAST bands is from DSFGs. We confirm and extend the BLAST analysis of clustering with an independent pipeline and also detect correlations between the ACT and BLAST maps at over 25σ significance, which we interpret as a detection of the DSFGs in the ACT maps. In addition to a Poisson component in the cross-frequency power spectra, we detect a clustered signal at 4σ , and using a model for the DSFG evolution and number counts, we successfully fit all of our spectra with a linear clustering model and a bias that depends only on redshift and not on scale. Finally, the data are compared to, and generally agree with, phenomenological models for the DSFG population. This study demonstrates the constraining power of the cross-frequency correlation technique to constrain models for the DSFGs. Similar analyses with more data will impose tight constraints on future models.

“…Several SZ surveys, including those being undertaken with the South Pole Telescope (SPT, Carlstrom et al 2011) survey, the Atacama Cosmology Telescope (ACT, Fowler et al 2007), and Planck (Tauber et al 2010), are actively ongoing and have started to provide the first SZ-selected cluster samples (e.g., Vanderlinde et al 2010;Menanteau et al 2010;Planck Collaboration 2011d). X-ray observations of SZ-detected clusters are important in many respects.…”

We present the compilation and properties of a meta-catalogue of X-ray detected clusters of galaxies, the MCXC. This very large catalogue is based on publicly available ROSAT All Sky Survey-based (NORAS, REFLEX, BCS, SGP, NEP, MACS, and CIZA) and serendipitous (160SD, 400SD, SHARC, WARPS, and EMSS) cluster catalogues. Data have been systematically homogenised to an overdensity of 500, and duplicate entries from overlaps between the survey areas of the individual input catalogues are carefully handled. The MCXC comprises 1743 clusters with virtually no duplicate entries. For each cluster the MCXC provides three identifiers, a redshift, coordinates, membership in the original catalogue, and standardised 0.1−2.4 keV band luminosity L 500 , total mass M 500 , and radius R 500 . The meta-catalogue additionally furnishes information on overlaps between the input catalogues and the luminosity ratios when measurements from different surveys are available, and gives notes on individual objects. The MCXC is available in electronic format for maximum usefulness in X-ray, SZ, and other multiwavelength studies.

“…Despite early detections of this effect (Gull & Northover 1976), it is only recently that instrumentation advances have made large-scale SZ searches feasible. There are three such ongoing surveys: one carried out with the South Pole Telescope (SPT; Carlstrom et al 2011), one with the Atacama Cosmology Telescope (ACT; Fowler et al 2007), and one using the Planck satellite (Planck Collaboration 2011a). All three surveys have published initial cluster samples (Vanderlinde et al 2010;Marriage et al 2011;Planck Collaboration 2011c), and are expected to eventually publish hundreds of SZ-selected systems out to z = 1 and beyond.…”

Sunyaev-Zeldovich (SZ) clusters surveys, such as Planck, the South Pole Telescope, and the Atacama Cosmology Telescope, will soon be publishing several hundred SZ-selected systems. The key ingredient required to transport the mass calibration from current X-ray-selected cluster samples to these SZ systems is the Y SZ -Y X scaling relation. We constrain the amplitude, slope, and scatter of the Y SZ -Y X scaling relation using SZ data from Planck and X-ray data from Chandra. We find a best-fit amplitude of ln(D 2 A Y SZ /CY X ) = −0.202 ± 0.024 at the pivot point CY X = 8 × 10 −5 Mpc 2 . This corresponds to a Y SZ /Y X ratio of 0.82 ± 0.024, in good agreement with X-ray expectations after including the effects of gas clumping. The slope of the relation is α = 0.916 ± 0.032, consistent with unity at ≈2.3σ . We are unable to detect intrinsic scatter, and find no evidence that the scaling relation depends on cluster dynamical state.
