Evidence for a high-z ISW signal from supervoids in the distribution of eBOSS quasars
A. Kovács, R. Beck, A. Smith +3
The late-time integrated Sachs-Wolfe (ISW) imprint of super-structures is sourced by evolving large-scale potentials due to a dominant dark energy co…
The anisotropy of the power spectrum in periodic cosmological simulations
Gábor Rácz, István Szapudi, István Csabai +1
The classical gravitational force on a torus is anisotropic and always lower than Newton's law. We demonstrate the effects of periodicity in dark matter only -body simul…
A common explanation of the Hubble tension and anomalous cold spots in the CMB
András Kovács, Róbert Beck, István Szapudi +3
The standard cosmological paradigm narrates a reassuring story of a universe currently dominated by an enigmatic dark energy component. Disquietingly, its universal explaining powe…
StePS: A Multi-GPU Cosmological N-body Code for Compactified Simulations
Gábor Rácz, István Szapudi, László Dobos +2
We present the multi-GPU realization of the StePS (Stereographically Projected Cosmological Simulations) algorithm with MPI-OpenMP-CUDA hybrid parallelization and nearly ideal scal…
The integrated Sachs-Wolfe effect in the AvERA cosmology
Róbert Beck, István Csabai, Gábor Rácz +1
The recent AvERA cosmological simulation of Rácz et al. (2017) has a -like expansion history and removes the tension between local and Planck (cosmic microwave backg…
Compactified Cosmological Simulations of the Infinite Universe
Gábor Rácz, István Szapudi, István Csabai +1
We present a novel -body simulation method that compactifies the infinite spatial extent of the Universe into a finite sphere with isotropic boundary conditions to follow the ev…
Concordance cosmology without dark energy
Gábor Rácz, László Dobos, Róbert Beck +2
According to the separate universe conjecture, spherically symmetric sub-regions in an isotropic universe behave like mini-universes with their own cosmological parameters. This is…
Main-Belt Asteroids in the K2 Engineering Field of View
R. Szabó, K. Sárneczky, Gy. M. Szabó +6
Unlike NASA's original Kepler Discovery Mission, the renewed K2 Mission will stare at the plane of the Ecliptic, observing each field for approximately 75 days. This will bring new…
