Planck: SZ machine • Weak signal, contaminated by CMB and foregrounds • Clusters published in 2011 with S/N>6 ie S/N~1 per map ! • S/N >4.5 in 2015 release • Planck beam ~7arcmin High purity means: Detection, Validation, Confirmation 5 M. Douspis, 01/12/2015, SZ Meta-Catalogue

«manual» validation • Internal Planck checks (CC, IRPS, SSO) • Matching with existing catalogues • Search in logs and databases • Search in data (RASS, SDSS) Planck early VIII 2011 6 M. Douspis, 01/12/2015, SZ Meta-Catalogue

«Automatic» validation • For each candidate: F( ν ) = A SZ F SZ ( ν ) + A CMB F CMB ( ν ) + A IR F IR ( ν )+ A RAD F RAD ( ν ) + A CO F CO ( ν ) + N( ν ) • Use of Neural network and training sets to separate good, bad, and ugly candidates • 3 numbers / candidate Aghanim et al. 2015 7 M.

Douspis, 01/12/2015, SZ Meta-Catalogue

ex. PSZ1 catalogue PSZ1 based on [100-857]GHz 3 detection algorithms on ~84% of sky • 1227 clusters & candidates • 683 previously known • 264 new clusters • 280 candidates (class1-2-3) • z in [0-1] • M in [1~20] 10 14 M ☉ • M med ~ 3.5 10 14 M ☉ • z, z_source, z_type, z_ref, Y, M500, Qn, Pos_X, alt_name, ... • see Planck legacy archive 10 M.

South Pole Telescope & Atacama Cosmology Telescope • SPT since 2009 • ACT since 2009 • First blindly discovered SZ • 148 GHz + optical Fus cluster • 5 years observation • 95,150, 220 Ghz • 91 clusters and candidates • 747 clusters and candidates • ACT -Pol ongoing • SPT -Pol ongoing Bleem et al. 2015 Hasselfield et al. 2013 11 M. Douspis, 01/12/2015, SZ Meta-Catalogue

Why a meta-catalogue ? • Planck provides well caracterised catalogues over the full sky but limited range of redshift • SPT, ACT, AMI, Carma are lists of samples, part of the sky but higher resolution, thus higher z • Overlap and complementarity between samples • Known clusters • complementary information, ease comparison, ... • Candidates • list with usefull info for FUs Create a unique reference catalogue with homogenized quantities as MCXC ( Piffaretti et al. 2011 ) is for Xray 12 M. Douspis, 01/12/2015, SZ Meta-Catalogue

Building meta-catalogue • Compile from litterature list of clusters and candidates • Use previous associations (eg. Planck catalogues) • Make positional association between lists + checks • Chose a reference coordinates (SPT>ACT>PSZ2>PSZ1>ESZ>AMI>CARMA) • Chose a reference redshift (spec>phot, PSZ1>) • Agregate informations from all experiments • Distribute and allow for query • szcluster-db.ias.u-psud.fr (Sitools) + VO 13 M.

example of use • Scaling relation between mass estimates of different experiments (PLCK/ACT/ SPT) • Indirect measure of the compatible SZ signal seen by SPT and Planck as masses agree for the same cosmology Douspis et al. 2015 • Tcmb(z) Hurier et al. 2014, Guzzi et al. 2015 • other mass comparisons Van der linden et al. 2014, Israel et al. 2015, Ilic et al. 2015 17 M.
