Cosmic Momentum Field and Mass Fluctuation Power Spectrum
We introduce the cosmic momentum field as a new measure of the large-scale peculiar velocity and matter fluctuation fields. The momentum field is defined as the peculiar velocity field traced and weighted by galaxies, and is equal to the velocity field in the linear regime. We show that the radial component of the momentum field can be considered as a scalar field with the power spectrum which ...
متن کاملPower Spectrum of Cosmic Momentum Field Measured from the Sfi Galaxy Sample
We have measured the cosmic momentum power spectrum from the peculiar velocities of galaxies in the SFI sample. The SFI catalog contains field spiral galaxies with radial peculiar velocities derived from the I-band Tully-Fisher relation. As a natural measure of the large-scale peculiar velocity field, we use the cosmic momentum field that is defined as the peculiar velocity field weighted by lo...
متن کاملThe local power spectrum and correlation hierarchy of the cosmic mass field
We analyze the power spectrum of a QSO's Lyα transmitted flux in the discrete wavelet transform (DWT) representation. Although the mean DWT power spectrum is consistent with its counterpart in Fourier representation, the spatial distribution of the local power varies greatly, i.e. the local DWT power spectra show remarkably spiky structures on small scales. To measure these spiky features , we ...
متن کاملCosmic string formation and the power spectrum of field configurations.
We examine the statistical properties of defects formed by the breaking of a U(1) symmetry when the Higgs field has a power spectrum P (k) ∝ kn. We find a marked dependence of the amount of infinite string on the spectral index n and empirically identify an analytic form for this quantity. We also confirm that this result is robust to changes in the definition of infinite string. It is possible...
متن کاملLong-Term Modulation of the Galactic Cosmic-Ray Fluctuation Spectrum
We study the temporal behavior of the power spectra for Galactic cosmic-ray fluctuations during the last two solar cycles. We use the 5-min data for 1980–2002 corrected for the barometric effect from two widely separated high-latitude cosmic-ray stations, Tixie Bay and Oulu. The cosmicray fluctuation spectrum is shown to be subjected to a regular long-term modulation with a period of about 11 y...
