STEPSIC: Initial condition generator for stereographic cosmological simulations
Balázs Pál, Gábor Rácz, István Csabai +1
Conventional cosmological initial condition generators are designed exclusively for fully periodic cubic domains and cannot produce the non-periodic, observer-centric configuration…

Denoising medium resolution stellar spectra with U-Net convolutional neural networks
Balázs Pál, László Dobos
We investigated the use of a U-Net convolutional neural network for denoising simulated medium-resolution spectroscopic observations of stars. Simulated spectra were generated unde…

Simulating Rotating Newtonian Universes
Balázs Pál, Tze Goh, Gábor Rácz +1
We present the results of a novel type of numerical simulation that realizes a rotating Universe with a shear-free, rigid body rotation inspired by a Gödel-like metric. We run cos…
