A Lagrangian Perturbation Theory in the presence of massive neutrinos
Alejandro Aviles, Arka Banerjee
We develop a Lagrangian Perturbation Theory (LPT) framework to study the clustering of cold dark matter (CDM) in cosmologies with massive neutrinos. We follow the trajectories of C…
A fast particle-mesh simulation of non-linear cosmological structure formation with massive neutrinos
Adrian E. Bayer, Arka Banerjee, Yu Feng
Quasi-N-body simulations, such as FastPM, provide a fast way to simulate cosmological structure formation, but have yet to adequately include the effects of massive neutrinos. We p…
Nearest Neighbor distributions: new statistical measures for cosmological clustering
Arka Banerjee, Tom Abel
The use of summary statistics beyond the two-point correlation function to analyze the non-Gaussian clustering on small scales is an active field of research in cosmology. In this…
Investigating the use of field solvers for simulating classical systems
Andrew Eberhardt, Arka Banerjee, Michael Kopp +1
We explore the use of field solvers as approximations of classical Vlasov-Poisson systems. This correspondence is investigated in both electrostatic and gravitational contexts. We…
A Cross-Correlation Study of High-energy Neutrinos and Tracers of Large-Scale Structure
Ke Fang, Arka Banerjee, Eric Charles +1
The origin of the bulk of the astrophysical neutrinos detected by the IceCube Observatory remains a mystery. Previous source-finding analyses compare the directions of IceCube even…
Signatures of Velocity-Dependent Dark Matter Self-Interactions in Milky Way-mass Halos
Ethan O. Nadler, Arka Banerjee, Susmita Adhikari +2
We explore the impact of elastic, anisotropic, velocity-dependent dark matter (DM) self-interactions on the host halo and subhalos of Milky Way (MW)--mass systems. We consider a ge…
