Learning Cosmology from Nearest Neighbour Statistics
Atrideb Chatterjee, Arka Banerjee, Francisco Villaescusa-Navarro +1
Extracting cosmological parameters from galaxy/halo catalogues with sub-percent level accuracy is an important aspect of modern cosmology, especially in view of ongoing and upcomin…
Geometric Interpretations of the -Nearest Neighbour Distributions
Kwanit Gangopadhyay, Arka Banerjee, Tom Abel
The -Nearest Neighbour Cumulative Distribution Functions are measures of clustering for discrete datasets that are fast and efficient to compute. They are significantly more inf…
A Parameter-Masked Mock Data Challenge for Beyond-Two-Point Galaxy Clustering Statistics
2pt Collaboration, Elisabeth Krause, Yosuke Kobayashi +23
The last few years have seen the emergence of a wide array of novel techniques for analyzing high-precision data from upcoming galaxy surveys, which aim to extend the statistical a…
Robust cosmological inference from non-linear scales with k-th nearest neighbor statistics
Sihan Yuan, Tom Abel, Risa H. Wechsler
We present the methodology for deriving accurate and reliable cosmological constraints from non-linear scales (<50Mpc/h) with k-th nearest neighbor (kNN) statistics. We detail our…
Small-scale signatures of primordial non-Gaussianity in k-Nearest Neighbour cumulative distribution functions
William R. Coulton, Tom Abel, Arka Banerjee
Searches for primordial non-Gaussianity in cosmological perturbations are a key means of revealing novel primordial physics. However, robustly extracting signatures of primordial n…
The Properties of Cosmic Velocity Fields
Oliver Hahn, Raul E. Angulo, Tom Abel
Understanding the velocity field is very important for modern cosmology: it gives insights to structure formation in general, and also its properties are crucial ingredients in mod…
The Warm DM halo mass function below the cut-off scale
Raul E. Angulo, Oliver Hahn, Tom Abel
Warm Dark Matter (WDM) cosmologies are a viable alternative to the Cold Dark Matter (CDM) scenario. Unfortunately, an accurate scrutiny of the WDM predictions with N-body simulatio…
How closely do baryons follow dark matter on large scales?
Raul E. Angulo, Oliver Hahn, Tom Abel
We investigate the large-scale clustering and gravitational interaction of baryons and dark matter (DM) over cosmic time using a set of collisionless N-body simulations. Both compo…
