Abstract:
We provide the first combined cosmological analysis of the South Pole
Telescope (SPT) and Planck cluster catalogs. The aim is to provide an
independent calibration for Planck scaling relations, exploiting the
cosmological constraining power of the SPT-SZ cluster catalog and its
dedicated weak lensing (WL) and X-ray follow-up observations. We build
a new version of the Planck cluster likelihood. In the νΛCDM
scenario, focusing on the mass slope and mass bias of Planck scaling
relations, we find αSZ=1.49-0.10+0.07 and
(1-b)SZ=0.69-0.14+0.07, respectively. The results for the mass
slope show a ∼4σ departure from the self-similar evolution,
αSZ∼1.8. This shift is mainly driven by the matter density
value preferred by SPT data, Ωm=0.30±0.03, lower than the
one obtained by Planck data alone, Ωm=0.37-0.06+0.02. The
mass bias constraints are consistent both with outcomes of
hydrodynamical simulations and external WL calibrations, (1-b)∼0.8,
and with results required by the Planck cosmic microwave background
cosmology, (1-b)∼0.6. From this analysis, we obtain a new catalog of
Planck cluster masses M500. We estimate the ratio between the
published Planck MSZ masses and our derived masses M500, as a
"measured mass bias", (1-b)M. We analyze the mass, redshift, and
detection noise dependence of (1-b)M, finding an increasing trend
toward high redshift and low mass. These results mimic the effect of
departure from self-similarity in cluster evolution, showing different
dependencies for the low-mass, high-mass, low-z, and high-z regimes.
Description:
In this work, we perform the first combined cosmological analysis of
the SPT-SZ (Bleem+ 2015, J/ApJS/216/27 and Bocquet+ 2019, J/ApJ/878/55)
and Planck (Planck+ 2016, J/A+A/594/A27) cluster catalogs. Both
experiments detect clusters in the millimeter wavelengths through the
thermal Sunyaev-Zeldovich (tSZ) effect.
We recall here that clusters detected through the thermal
Sunyaev-Zeldovich effect are often defined as objects with a mass
M500 contained in a sphere of radius R500, such that the cluster
mean mass overdensity inside R500 corresponds to 500 times the
critical density ρc(z). Therefore, we define the total cluster
mass as:
M500=(4π/3)R3500500ρc(z)
The South Pole Telescope (SPT) is a 10m diameter telescope located at
the geographic south pole. We consider observations of the SPT-SZ
survey (Bleem+ 2015), which detected galaxy clusters through the tSZ
effect, using observations in the 95 and 150GHz bands, in a 2500deg2
area. With a resolution and 1° field of view, SPT is able to
observe rare, high-mass clusters, from redshift z≳0.2. See Section 2.1.
The Planck satellite is a mission from the European Space Agency
(ESA), which concluded the observations in 2013. The Planck cluster
catalog (Planck+ 2016) is based on full-sky observations from the six
channels of the High Frequency Instrument (HFI), in the frequency
range 100-857GHz. See Section 2.2.
