: A Differentiable -based Code for Radiative Transfer in Curved Spacetimes
Pedro Naethe Motta, Ben S. Prather, Alejandro Cárdenas-Avendaño
Recent imaging of supermassive black holes by the Event Horizon Telescope (EHT) has relied on exhaustive parameter-space searches, matching observations to large, precomputed libra…
Estimating High-Order Time Derivatives of Kerr Orbital Functionals
Lennox S. Keeble, Alejandro Cárdenas-Avendaño
Functions of bound Kerr geodesic motion play a central role in many calculations in relativistic astrophysics, ranging from gravitational-wave generation to self-force and radiatio…
Cumulative effect of orbital resonances in extreme-mass-ratio inspirals
Edoardo Levati, Alejandro Cárdenas-Avendaño, Kyriakos Destounis +1
Orbital resonances in extreme-mass-ratio inspirals (EMRIs) have been proven to be a key feature for accurate gravitational-wave template modeling. Decades of research have led to s…
Inferring Black Hole Spin from Interferometric Measurements of the First Photon Ring: A Geometric Approach
Lennox S. Keeble, Alejandro Cárdenas-Avendaño, Daniel C. M. Palumbo
Accurately inferring black hole spin is crucial for understanding black hole dynamics and their astrophysical environments. In this work, we outline a geometric method for spin est…
