Brahmanda — Large-Scale Structure Physics

ब्रह्माण्ड (Sanskrit: the cosmic egg, the universe)

Galactic structure, cosmic web topology, dark matter halos, and cosmological structure formation. Part of the AGNOS science stack.

Modules

• morphology — Galaxy classification (Hubble types), Sersic profiles, Faber-Jackson and Tully-Fisher scaling relations
• halo — Dark matter halos: NFW density profiles, virial relations, concentration-mass relations, enclosed mass and circular velocity
• cosmic_web — Cosmic web topology: filament/void/sheet/node classification via tidal tensor eigenvalues, density contrast, two-point correlation
• power_spectrum — Matter power spectrum: Eisenstein-Hu transfer function, primordial power, linear growth factor, σ(R) mass fluctuations
