1
Weak lensing mass-selected cluster catalogues Richard Massey (CalTech) with Justin Albert (CalTech), Joel Berge (Saclay), Richard Ellis (CalTech), Takashi Hamana (Tokyo), Jean-Paul Kneib (Marseille), Alexie Leauthaud (Marseille), Satoshi Miyazaki (Subaru), Alexandre Refregier (Saclay), Jason Rhodes (JPL), Nick Scoville (CalTech), James Taylor (CalTech) and the COSMOS team
2
Lensing sensitivity with redshift Number of resolved galaxies z
3
Clusters are just… patterns in a shear field
4
Patterns in a shear field
5
Mass maps from ACS data
6
Residual systematics in ACS data
7
E-mode signal B-mode signal Theory
8
Wavelet reconstruction
9
Mass vs light Nick Scoville
10
Mass vs x-rays Gunther Hasinger, Alexis Finoguenov & Nico Cappelluti
11
Tomography (3D maps) Number of resolved galaxies z
12
Tomography (3D maps)
13
Tomography (3D maps): z~0.3
14
Tomography (3D maps): z~0.5
15
Tomography (3D maps): z~0.7
16
Shear measurement from Subaru Deconvolve from the ground-based PSF using shapelets. ~25 galaxies/arcmin 2 with Subaru data, rather than ~60 galaxies/arcmin 2 using ACS Subaru shear (shapelets)
17
Subaru mass maps
19
Residual systematics in Subaru data 1% level residuals
20
FITS versions of all these maps available at: www.astro.caltech.edu/~rjm/mass_mapsConclusions Projected 2D mass maps Somewhat coarser 3D mass maps More optimally-tuned analysis around identified structures Systematics checks: E/B-mode split Systematics checks: ground vs space
