Neural network reconstruction of density and velocity fields from the 2MASS Redshift Survey
Robert Lilow, Punyakoti Ganeshaiah Veena, Adi Nusser
We reconstruct the 3D matter density and peculiar velocity fields in the local Universe up to a distance of 200Mpc from the Two-Micron All-Sky Redshift Survey (2MRS), u…
Baryon-photon interactions in Resummed Kinetic Field Theory
Ivan Kostyuk, Robert Lilow, Matthias Bartelmann
We explore how interactions between baryons and photons can be incorporated into Kinetic Field Theory (KFT), a description of cosmic structure formation based on classical Hamilton…
Large-scale density and velocity field reconstructions with neural networks
Punyakoti Ganeshaiah Veena, Robert Lilow, Adi Nusser
We assess a neural network (NN) method for reconstructing 3D cosmological density and velocity fields (target) from discrete and incomplete galaxy distributions (input). We employ…
A new measurement of the Hubble constant using Fast Radio Bursts
Steffen Hagstotz, Robert Reischke, Robert Lilow
Fast radio bursts (FRBs) are very short and bright transients visible over extragalactic distances. The radio pulse undergoes dispersion caused by free electrons along the line of…
Consistent equivalence principle tests with fast radio bursts
Robert Reischke, Steffen Hagstotz, Robert Lilow
Fast radio bursts (FRBs) are astrophysical transients of still debated origin. So far several hundred events have been detected, mostly at extragalactic distances, and this number…
Constrained realizations of 2MRS density and peculiar velocity fields: growth rate and local flow
Robert Lilow, Adi Nusser
We generate constrained realizations (CRs) of the density and peculiar velocity fields within from the final release of the Two-Micron All-Sky Redsh…
A first comparison of Kinetic Field Theory with Eulerian Standard Perturbation Theory
Elena Kozlikin, Robert Lilow, Felix Fabis +1
We present a detailed comparison of the newly developed particle-based Kinetic Field Theory framework for cosmic large-scale structure formation with the established formalism of E…
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…
Probing primordial non-Gaussianity with Fast Radio Bursts
Robert Reischke, Steffen Hagstotz, Robert Lilow
Fast radio bursts (FRBs) are astrophysical transients of currently unknown origin, and so far several events have been detected at extragalactic distances. The dispersion measure (…
Resummed Kinetic Field Theory: a model of coupled baryonic and dark matter
Daniel Geiss, Ivan Kostyuk, Robert Lilow +1
We present a new analytical description of cosmic structure formation in a mixture of dark and baryonic matter, using the framework of Kinetic Field Theory (KFT) -- a statistical f…
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…
Resummed Kinetic Field Theory: Using Mesoscopic Particle Hydrodynamics to Describe Baryonic Matter in a Cosmological Framework
Daniel Geiss, Robert Lilow, Felix Fabis +1
Recently, Bartelmann et al. presented a 'Kinetic Field Theory' (KFT) formalism to tackle the difficulties of large scale structure formation. In this approach, the dynamics of a no…
Resummed Kinetic Field Theory: general formalism and linear structure growth from Newtonian particle dynamics
Robert Lilow, Felix Fabis, Elena Kozlikin +2
In earlier work, we have developed a nonequilibrium statistical field theory description of cosmic structure formation, dubbed Kinetic Field Theory (KFT), which is based on the Ham…
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…

Non-equilibrium statistical field theory for classical particles: Linear and mildly non-linear evolution of cosmological density power spectra
Matthias Bartelmann, Felix Fabis, Daniel Berg +3
We use the non-equlibrium statistical field theory for classical particles, recently developed by Mazenko and Das and Mazenko, together with the free generating functional we have…
