Excess of high- galaxies as a test for bumpy power spectrum of density perturbations
M. V. Tkachev, S. V. Pilipenko, E. V. Mikheeva +1
Modified matter power spectra with approximately Gaussian bump on sub-Mpc scales can be a result of a complex inflation. We consider five spectra with different Gaussian amplitudes…
Simulating the LOcal Web (SLOW): I. Anomalies in the local density field
Klaus Dolag, Jenny G. Sorce, Sergey Pilipenko +5
Context: Several observations of the local Universe (LU) point towards the existence of very prominent structures. The presence of massive galaxy clusters and local super clusters…
The evolution of a primordial binary black hole due to interaction with cold dark matter and the formation rate of gravitational wave events
Sergey Pilipenko, Maxim Tkachev, Pavel Ivanov
In this Paper we consider a problem of formation and evolution of orbital parameters of a binary primordial black hole (PBH) due to gravitational interaction with clustering cold d…
Dark Matter Simulations with Primordial Black Holes in the Early Universe
Maxim Tkachev, Sergey Pilipenko, Gustavo Yepes
Primordial Black Holes (PBH) with masses of order have been proposed as a possible explanation of the gravitational waves emission events recently discovered by the…
A Model of the Cosmic Infrared Background Produced by Distant Galaxies
S. V. Pilipenko, M. V. Tkachev, A. A. Ermash +3
The extragalactic background radiation produced by distant galaxies emitting in the far infrared limits the sensitivity of telescopes operating in this range due to confusion. We h…
Pushing down the low-mass halo concentration frontier with the Lomonosov cosmological simulations
Sergey V. Pilipenko, Miguel A. Sánchez-Conde, Francisco Prada +1
We introduce the Lomonosov suite of high-resolution N-body cosmological simulations covering a full box of size 32 Mpc with low-mass resolution particles ( $h…
