Expanding stellar associations as Galactic accelerometers
Till Sawala, Núria Miret Roig
The gravitational potential of the Milky Way is fundamental for understanding the evolution of our Galaxy and the nature of dark matter. We introduce a new method to constrain the…

The local galaxy distribution does not violate the cosmological principle
Till Sawala
The cosmological principle, which states that the Universe is statistically homogeneous and isotropic on sufficiently large scales, is a foundational assumption of the standard cos…

Cylindrical cosmological simulations with StePS
Gábor Rácz, Viola H. Varga, Balázs Pál +3
The global topology of the Universe can affect long-range gravitational forces via boundary conditions. Detailed studies of non-trivial topologies require simulations that natively…
