TL;DR: The Extended Baryon Oscillation Spectroscopic Survey (eBOSS) as discussed by the authors uses four different tracers to measure the distance-redshift relation with baryon acoustic oscillations (BAO).

TL;DR: In this article, the authors used a high-resolution cosmological hydro/N-body simulation with star formation and compared the measured merger timescales with theoretical predictions based on the Chandrasekhar formula.

TL;DR: In this article, a controlled set of high-resolution cosmological simulations to quantify the effect of baryons on weak-lensing signal at scales corresponding to multipole moments 100 < l < 10,000 was used.

TL;DR: In this article, the authors compare two algorithms for finding cosmic filaments and sheets, a task which is far less well established than the identification of dark matter halos or voids, and find that both the spin and major axes of filament halos with masses 1013 h − 1 M ☉ are preferentially aligned with the direction of the filaments.

TL;DR: In this article, the Hamiltonian Markov Chain Monte Carlo (HMC) algorithm combined with Particle-mesh (PM) dynamics is applied to cosmological simulations, and the reconstructed linear density fields are then evolved to the present day with N-body simulations.
