Measuring Dark Energy Using Galaxy Surveys
WebApr 20, 2024 · Combining with the halo occupation distribution to model the galaxy-halo connection, we can compute the redshift-space power spectrum of BOSS-like galaxies in less than a CPU second, for an input model under flat ΛCDM cosmology. The matter power spectrum describes the density contrast of the universe (the difference between the local density and the mean density) as a function of scale. It is the Fourier transform of the matter correlation function. On large scales, gravity competes with cosmic expansion, and structures grow … See more Let $${\displaystyle \delta (\mathbf {x} )}$$ represent the matter overdensity, a dimensionless quantity defined as: $${\displaystyle \delta (\mathbf {x} )={\frac {\rho (\mathbf {x} )-{\bar {\rho }}}{\bar {\rho }}},}$$ See more If the autocorrelation function describes the probability of a galaxy at a distance $${\displaystyle r}$$ from another galaxy, the matter power spectrum decomposes this probability into characteristic lengths, $${\displaystyle k\approx 2\pi /L}$$, and its amplitude … See more WebAug 30, 2006 · We present a Fourier analysis of the clustering of galaxies in the combined Main galaxy and Luminous Red Galaxy (LRG) Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) sample. The aim of our analysis is to consider how well we can measure the cosmological matter density using the signature of the horizon at matter-radiation … saya the robot
