Observational Constraints on Horizonless Compact Objects from Thermal Emission in AGNs

Ekin Oran, Avery Broderick, Kiana Salehi

The Swift Burst Alert Telescope Active Galactic Nuclei Spectroscopic Survey (BASS DR2) provides one of the largest and most complete samples of bright, local (z < 0.1) active galac…

Measuring the Shape of Kerr Black Holes at the Photon Orbit

Kiana Salehi, Avery Broderick

The bright ring-like structures observed in the images of M87* and SgrA* captured by the Event Horizon Telescope strongly support the validity of general relativity. Lensed images…

Influence of Observer Inclination and Spacetime Structure on Photon Ring Observables

Kiana Salehi, Rahul Kumar Walia, Dominic Chang +1

Recent observations of the near-horizon regions of BHs, particularly the images captured by the Event Horizon Telescope (EHT) collaboration, have greatly advanced our understanding…

Spacetime Measurements with the Photon Ring

Rahul Kumar Walia, Prashant Kocherlakota, Dominic O. Chang +1

We explore the universal symmetries of the black hole photon ring in a wide range of non-Kerr spacetimes, including the Kerr-Newman, Kerr-Sen, Kerr-Bardeen, and Kerr-Hayward metric…

Cosmic Censorship in Sgr A* and M87*: Observationally Excluding Naked Singularities

Avery E. Broderick, Kiana Salehi

The imaging of Sagittarius A* (Sgr A*) and the supermassive black hole at the center of Messier 87 (M87*) by the Event Horizon Telescope constrains the location and nature of emiss…

Photon Rings and Shadow Size for General Integrable Spacetimes

Kiana Salehi, Avery Broderick, Boris Georgiev

There are now multiple direct probes of the region near black hole horizons, including direct imaging with the Event Horizon Telescope (EHT). As a result, it is now of considerable…
