The Structure in the Structure Function of Black Hole Light Curves
Daniel C. M. Palumbo, Alejandro Cárdenas-Avendaño, Lena Murchikova
Of the two black holes, M87 and Sgr~A, for which event-horizon-scale imaging is currently achievable, only Sgr~A at our Galactic Center exhibits sub-hour varia…
Bayesian Evidence for Inspiraling Hotspot Motion in the Galactic Center
Pablo Ruales, Maciek Wielgus, Delilah E. A. Gates +1
During flaring episodes, polarimetric observations of the Galactic Center black hole Sagittarius A* (Sgr A*) reveal evolving, loop-like trajectories in the Stokes Q-U plane, the so…
A Four-Dimensional Gaussian Random Field Generator for Modeling Spatiotemporal Variability in Astrophysical Sources
Alejandro Cárdenas-Avendaño, Diego Rubiera-Garcia, Frederic H. Vincent
Semi-analytic models of black-hole movies require both an emitting flow prescription and a time-dependent source variability. Existing prescriptions are often limited to either equ…
Light Propagation Prescriptions for Black Hole Movies
Daniel Rojas-Paternina, Alejandro Cárdenas-Avendaño
The spatiotemporal content of a black-hole movie is set jointly by source variability and by the distribution of light-travel times across the image. In the slow-light prescription…
Sensitivities of Black Hole Images from GRMHD Simulations
Pedro Naethe Motta, Mário Raia Neto, Cora Prather +1
The advent of high-fidelity imaging of supermassive black holes calls for efficient and robust data-analysis methods. In this work, we use , a differentiable, $\te…
Polarization Signatures of Inspiraling Hotspots around Kerr Black Holes
Pablo Ruales, Delilah E. A. Gates, Alejandro Cárdenas-Avendaño
Polarimetric interferometry is a powerful tool for probing both black hole accretion physics and the background spacetime. Current models aimed at explaining the observed multiwave…
Multidisciplinary Science in the Multimessenger Era
Eric Burns, Christopher L. Fryer, Ivan Agullo +82
Astrophysical observations of the cosmos allow us to probe extreme physics and answer foundational questions on our universe. Modern astronomy is increasingly operating under a hol…
