Polarized Equatorial Emission around Kerr Black Holes with Synchronized Scalar Hair. I. Direct images
Valentin O. Deliyski, Galin N. Gyulchev, Daniela D. Doneva +2
We investigate the polarization properties of the direct images of a geometrically and optically thin accretion disk around fully self-consistent models of rotating Kerr black hole…
Images of the Thin Accretion Disk Around Kerr Black Holes coupled to time periodic scalar fields
Galin N. Gyulchev, Daniela D. Doneva, Valentin O. Deliyski +2
We investigate the orbital structure and observable appearance of rotating Kerr black holes endowed with synchronized scalar hair described by two time-periodic scalar fields with…
Observing naked singularities by the present and next-generation Event Horizon Telescope
Valentin Deliyski, Galin Gyulchev, Petya Nedkova +1
We consider the observational signatures of reflective naked singularities as seen by the current and next-generation Event Horizon Telescope (EHT). The reflective naked singularit…
Polarized image of equatorial emission in horizonless spacetimes: naked singularities
Valentin Deliyski, Galin Gyulchev, Petya Nedkova +1
We study the linear polarization from the accretion disk around weakly and strongly naked Janis-Newman-Winicour singularities. We consider an analytical toy model of thin magnetize…
