  • Toward efficient effective-one-body models for generic, nonplanar orbits 
    Gamba, Rossella; Chiaramello, Danilo; NEOGI, SAYAN (American Physical Society, 2024-07)
    Complete waveform models able to account for arbitrary nonplanar orbits represent a holy grail in current gravitational-wave astronomy. Here, we take a step toward this direction and present a simple yet efficient prescription ...
  • Generalized gravity theories 
    NEOGI, SAYAN (2025-05)
    This thesis explores the existence of higher-derivative theories beyond the Lanczos-Lovelock models of gravity which are ghost-free in arbitrary backgrounds by having a second-order equation of motion (which we shall refer ...
