On -body simulations of globular cluster stream
Nilanjan Banik, Jo Bovy
Stellar tidal streams are sensitive tracers of the properties of the gravitational potential in which they orbit and detailed observations of their density structure can be used to…
Towards constraining warm dark matter with stellar streams through neural simulation-based inference
Joeri Hermans, Nilanjan Banik, Christoph Weniger +2
A statistical analysis of the observed perturbations in the density of stellar streams can in principle set stringent contraints on the mass function of dark matter subhaloes, whic…
Effects of baryonic and dark matter substructure on the Pal 5 stream
Nilanjan Banik, Jo Bovy
Gravitational encounters between small-scale dark matter substructure and cold stellar streams in the Milky Way halo lead to density perturbations in the latter, making streams an…
The Formation of Supermassive Black Holes from Population III.1 Seeds. I. Cosmic Formation Histories and Clustering Properties
Nilanjan Banik, Jonathan C. Tan, Pierluigi Monaco
We calculate cosmic distributions in space and time of the formation sites of the first, "Pop III.1" stars, exploring a model in which these are the progenitors of all supermassive…
Galactoseismology and the Local Density of Dark Matter
Nilanjan Banik, Lawrence M. Widrow, Scott Dodelson
We model vertical breathing mode perturbations in the Milky Way's stellar disc and study their effects on estimates of the local dark matter density, surface density, and vertical…
Axions and the Galactic Angular Momentum Distribution
N. Banik, P. Sikivie
We analyze the behavior of axion dark matter before it falls into a galactic gravitational potential well. The axions thermalize sufficiently fast by gravitational self-interaction…
