Free Cosmic Density Bispectrum on Small Scales
Ricardo Waibel, Sara Konrad, Matthias Bartelmann
We study the asymptotic behaviour of the free, cold-dark matter density fluctuation bispectrum in the limit of small scales. From an initially Gaussian random field, we draw phase-…
Gravitational Turbulence: the Small-Scale Limit of the Cold-Dark-Matter Power Spectrum
Yonadav Barry Ginat, Michael L. Nastac, Robert J. Ewart +3
The matter power spectrum, , is one of the fundamental quantities in the study of large-scale structure in cosmology. Here, we study its small-scale asymptotic limit, and sho…
Kinetic Field Theory for Cosmic Structure Formation
Sara Konrad, Matthias Bartelmann
We apply kinetic field theory to non-linear cosmic structure formation. Kinetic field theory decomposes the cosmic density field into particles and follows their trajectories throu…
On the asymptotic behaviour of cosmic density-fluctuation power spectra of cold dark matter
Sara Konrad, Yonadav Barry Ginat, Matthias Bartelmann
We study the small-scale asymptotic behaviour of the cold dark matter density fluctuation power spectrum in the Zel'dovich approximation, without introducing an ultraviolet cut-off…
On the asymptotic behaviour of cosmic density-fluctuation power spectra
Sara Konrad, Matthias Bartelmann
We study the small-scale asymptotic behaviour of the cosmic density-fluctuation power spectrum in the Zel'dovich approximation. For doing so, we extend Laplace's method in arbitrar…
Asymptotic Expansion of Laplace-Fourier-Type Integrals
Sara Konrad, Matthias Bartelmann
We study the asymptotic behaviour of integrals of the Laplace-Fourier type with …
Kinetic field theory: Non-linear cosmic power spectra in the mean-field approximation
Matthias Bartelmann, Johannes Dombrowski, Sara Konrad +5
We use the recently developed Kinetic Field Theory (KFT) for cosmic structure formation to show how non-linear power spectra for cosmic density fluctuations can be calculated in a…
Cosmic Structure Formation with Kinetic Field Theory
Matthias Bartelmann, Elena Kozlikin, Robert Lilow +7
Kinetic Field Theory (KFT) is a statistical field theory for an ensemble of point-like classical particles in or out of equilibrium. We review its application to cosmological struc…
Analytic calculation of the non-linear cosmic density-fluctuation power spectrum in the Born approximation
Matthias Bartelmann, Felix Fabis, Sara Konrad +4
We derive a non-perturbative, closed, analytic equation for the non-linear power spectrum of cosmic density fluctuations. This result is based on our kinetic field theory (KFT) of…
Reconstructing the projected gravitational potential of galaxy clusters from galaxy kinematics
Eleonora Sarli, Sven Meyer, Massimo Meneghetti +3
We develop a method for reconstructing the two-dimensional, projected gravitational potential of galaxy clusters from observed line-of-sight velocity dispersions of cluster galaxie…
Joint reconstruction of galaxy clusters from gravitational lensing and thermal gas. II. Inversion of the thermal Sunyaev-Zel'dovich effect
Charles L. Majer, Sven Meyer, Sara Konrad +2
This paper continues a series in which we intend to show how all observables of galaxy clusters can be combined to recover the two-dimensional, projected gravitational potential of…
Joint reconstruction of galaxy clusters from gravitational lensing and thermal gas I. Outline of a non-parametric method
Sara Konrad, Charles L. Majer, Sven Meyer +2
We present a method to estimate the lensing potential from massive galaxy clusters for given observational X-ray data. The concepts developed and applied in this work can easily be…
