Hierarchical clustering and the BAO signature
Wojciech A. Hellwing, Roman Juszkiewicz, Rien van de Weygaert +1
In this contribution we present the preliminary results regarding the non-linear BAO signal in higher-order statistics of the cosmic density field. We use ensembles of N-body simul…
Professor "Nonlinear": Obituary and memoir for Roman Juszkiewicz (1952-2012)
Wojciech A. Hellwing
On 28th and 29th of January 2013 we held an international meeting in Zielona Góra (Poland) honouring the first anniversary of premature passing away^(1) of Professor Roman Juszkiew…
Dark Matter Gravitational Clustering With a Long-Range Scalar Interaction
Wojciech A. Hellwing, Roman Juszkiewicz
We explore the possibility of improving the CDM model at megaparsec scales by introducing a scalar interaction which increases the mutual gravitational attraction of dark matter…
How to simulate the Universe in a box? Testing modified gravity with a N-body simulation code
Wojciech A. Hellwing
In this paper we present preliminary results from cosmological simulations of modified gravity in the dark matter sector. Our results show improvements over standard cold dark matt…
