Evolution of Neutron Star Environment in the Galactic Halo : Implications for Dark Matter Accretion
Payaswinee Arvikar, Aseem Paranjape, Saee Dhawalikar
Neutron stars (NS) are one of the indirect detection probes for dark matter (DM). The presence of DM is known to affect the observable properties of NS. Theoretical calculations fo…
Cosmic Velocity Flows: from Theory to Observations
Saee Dhawalikar
The Large-Scale Structure (LSS) of the Universe forms a complex network of nodes, filaments, sheets, and voids known as the Cosmic Web. As current and upcoming galaxy surveys incre…
Sahyadri: A simulation suite for the cosmology dependence of the Cosmic Web
Saee Dhawalikar, Shadab Alam, Aseem Paranjape +1
The paper presents Sahyadri, a high‑resolution cosmological N‑body simulation suite that varies key cosmological parameters to enable precise studies of the low‑redshift Universe a…
Stabilizing simulation-based cosmological Fisher forecasts: a case study using the Voronoi volume function
Saee Dhawalikar, Aseem Paranjape, Shadab Alam
Forecasting cosmological constraints from halo-based statistics often suffers from instability in derivative estimates, especially when the number of simulations is limited. This i…
