Signatures of Black Hole Spin in Horizon-Scale Polarimetry
George N. Wong, Daniel C. M. Palumbo, Zachary Gelles +1
The paper investigates how the spin of a black hole influences polarized emission observed at event‑horizon scales with VLBI, separating effects due to photon propagation in Kerr s…
Black Hole Polarimetry: Universal Polarization of Synchrotron Radiation at the Horizon
Andrew Chael, Alexandru Lupsasca, George N. Wong +2
Polarized images of a black hole encode the direction of electromagnetic energy flow near its event horizon. Measuring polarization from near-horizon emission can help determine wh…
Locating the missing large-scale emission in the jet of M87* with short EHT baselines
Boris Georgiev, Paul Tiede, Sebastiano D. von Fellenberg +280
In Very-Long Baseline Interferometric arrays, nearly co-located stations probe the largest scales and typically cannot resolve the observed source. In the absence of large-scale st…
Black Hole Polarimetry II: The Connection Between Spin and Polarization
George N. Wong, Andrew Chael, Alexandru Lupsasca +1
We study synchrotron polarization in spatially resolved horizon-scale images, such as those produced by the Event Horizon Telescope (EHT). In both general relativistic magnetohydro…
Black hole mimickers: from theory to observation
Cosimo Bambi, Ramy Brustein, Vitor Cardoso +16
The black hole paradigm, while remarkably successful, raises fundamental questions-both classical and quantum-about the nature of spacetime, horizons, and singularities. Black hole…
Photon Ring Interferometric Signatures Beyond The Universal Regime
He Jia, Eliot Quataert, Alexandru Lupsasca +1
We calculate the interferometric signatures of black hole photon rings beyond the universal regime by perturbatively including the effects of finite ring width. Our approach first…
