Matter power spectrum reconstruction
Listed in IVOA Registry (Virtual Observatory)
Direct measurements of the matter power spectrum, Pm (k, z), provide a powerful tool to investigate observed tensions between models of structure growth while also testing the internal consistency of cosmological probes.
Description
We analyse cosmic shear data from the final data release of the Kilo- Degree Survey (KiDS), presenting a deprojected Pm (k, z), measured in up to three redshift bins. Compared to analyses using previous KiDS releases, we find improved internal consistency in the z<~0.7 regime.
At large scales, k<~0.1h/Mp, our power spectrum reconstruction aligns with {LAMBDA}CDM predictions with a density fluctuation amplitude {sigma}_8_=0.81. Furthermore, at small scales, k=3-20h/Mpc, the average matter power spectrum is suppressed by 30%+/-10% (stat.)+/-4% (sys.) with 2.8{sigma} significance relative to a dark-matter-only model, consistent with expectations of strong baryonic feedback.
