Cosmological N-Body Simulation Suite
Sahyadri
High-resolution N-body simulations for precision studies of the
low-redshift Universe. Designed for next-generation spectroscopic
surveys including DESI BGS and 4MOST.
Cosmic Web in Motion
Live volume renders of the Sahyadri density field — the full box, a single filament, and a zoom onto one collapsing halo.
HR
Ultra-High Resolution
~25× better mass resolution than AbacusSummit, >100× better than Quijote. Resolves halos down to 3.2 × 10⁹ h⁻¹ M☉.
NG
Designed for DESI & 4MOST
Resolves ~40% more DESI BGS galaxies at z < 0.15 than existing suites — approximately 1.6 million additional galaxies.
6P
Precision Cosmology
Six cosmological parameter variations with seed-matched ICs for clean derivatives, Fisher matrix analyses, and emulator construction.
3×
Efficient Data Products
Custom 3× compressed snapshots, halo catalogs, power spectra, mass functions, and pre-computed summary statistics.
B2
Beyond Two-Point
Ideal for Voronoi Volume Functions, kNN-CDFs, Minkowski functionals, and other higher-order statistics on non-linear scales.
DR
Public Data Release
Comprehensive data products with documentation, analysis examples, and learning resources for students and researchers.
