Detection of spatial clustering in the 1000 richest SDSS DR8 redMaPPer clusters with Nearest Neighbor distributions
Yunchong Wang, Arka Banerjee, Tom Abel +1
Distances to the -nearest-neighbor (NN) data points from volume-filling query points are a sensitive probe of spatial clustering. Here we present the first application of …
The Effects of Dark Matter and Baryonic Physics on the Milky Way Subhalo Population in the Presence of the Large Magellanic Cloud
Ethan O. Nadler, Arka Banerjee, Susmita Adhikari +2
Given recent developments in our understanding of the Large Magellanic Cloud's (LMC) impact on the Milky Way's (MW) dark matter subhalo population, we compare the signatures of dar…
Beware of Fake s: The Effect of Massive Neutrinos on the Nonlinear Evolution of Cosmic Structure
Adrian E. Bayer, Arka Banerjee, Uros Seljak
Massive neutrinos suppress the growth of cosmic structure on small, non-linear, scales. It is thus often proposed that using statistics beyond the power spectrum can tighten constr…
Modeling Nearest Neighbor distributions of biased tracers using Hybrid Effective Field Theory
Arka Banerjee, Nickolas Kokron, Tom Abel
We investigate the application of Hybrid Effective Field Theory (HEFT) -- which combines a Lagrangian bias expansion with subsequent particle dynamics from -body simulations --…
The Signatures of Self-Interacting Dark Matter and Subhalo Disruption on Cluster Substructure
Joy Bhattacharyya, Susmita Adhikari, Arka Banerjee +4
The abundance, distribution and inner structure of satellites of galaxy clusters can be sensitive probes of the properties of dark matter. We run 30 cosmological zoom-in simulation…
Clustering in Massive Neutrino Cosmologies via Eulerian Perturbation Theory
Alejandro Aviles, Arka Banerjee, Gustavo Niz +1
We introduce an Eulerian Perturbation Theory to study the clustering of tracers for cosmologies in the presence of massive neutrinos. Our approach is based on mapping recently-obta…
