Density-dependent clustering – I. Pullingback the curtains on motions of the BAO peak (2018)
Journal Article

The most common statistic used to analyse large-scale structure surveys is the correlation function, or power spectrum. Here, we show how ‘slicing’ the correlation function on local density brings sensitivity to interesting non-Gaussian features in t... Read More about Density-dependent clustering – I.

The cosmic spiderweb: equivalence of cosmic, architectural and origami tessellations (2018)
Journal Article
Neyrinck, M. C., Hidding, J., Konstantatou, M., & van de Weygaert, R. (2018). The cosmic spiderweb: equivalence of cosmic, architectural and origami tessellations. Royal Society Open Science, 5(4), Article 171582. https://doi.org/10.1098/rsos.171582

For over 20 years, the term ‘cosmic web’ has guided our understanding of the large-scale arrangement of matter in the cosmos, accurately evoking the concept of a network of galaxies linked by filaments. But the physical correspondence between the cos... Read More about The cosmic spiderweb: equivalence of cosmic, architectural and origami tessellations.

Scalable streaming tools for analyzing N-body simulations: Finding halos and investigating excursion sets in one pass (2018)
Journal Article
Ivkin, N., Liu, Z., Yang, L., Kumar, S., Lemson, G., Neyrinck, M., …Budavari, T. (2018). Scalable streaming tools for analyzing N-body simulations: Finding halos and investigating excursion sets in one pass. Astronomy and computing, 23, 166-179. https://doi.org/10.1016/j.ascom.2018.04.003

Cosmological NN-body simulations play a vital role in studying models for the evolution of the Universe. To compare to observations and make a scientific inference, statistic analysis on large simulation datasets, e.g., finding halos, obtaining multi...

The Effect of Corner Modes in the Initial Conditions of Cosmological Simulations (2017)
Journal Article

In view of future high-precision large-scale structure surveys, it is important to quantify the percent and subpercent level effects in cosmological N-body simulations from which theoretical predictions are drawn. One such effect involves deciding wh... Read More about The Effect of Corner Modes in the Initial Conditions of Cosmological Simulations.

The lensing and temperature imprints of voids on the cosmic microwave background (2016)
Journal Article
Cai, Y., Neyrinck, M., Mao, Q., Peacock, J. A., Szapudi, I., & Berlind, A. A. (2017). The lensing and temperature imprints of voids on the cosmic microwave background. Monthly Notices of the Royal Astronomical Society, 466(3), 3364-3375. https://doi.org/10.1093/mnras/stw3299

We have searched for the signature of cosmic voids in the cosmic microwave background (CMB), in both the Planck temperature and lensing-convergence maps; voids should give decrements in both. We use ZOBOV voids from the Data Release 12 Sloan Digital... Read More about The lensing and temperature imprints of voids on the cosmic microwave background.
