SMBH shadows: gravity fingerprints revealed by spectral line background radiation
Konstantinos Kostaros, Padelis Papadopoulos, Wing-Fai Thi +1
SMBHs at the centers of galaxies, illuminated by their accretion disks, can reveal valuable information on BH spacetimes via their shadows, which can be used for strong-gravity tes…
An Einstein ring fingerprint around SMBHs illuminated by BLR spectral lines
Konstantinos Kostaros, George Pappas, Padelis Papadopoulos +1
The continuum emission from the hot and ionized inner regions of a supermassive black hole (SMBH) accretion disk that is strongly lensed by the light-ring (i.e., the unstable photo…
The neutral gas phase nearest to supermassive black holes
Wing-Fai Thi, Padelis Papadopoulos
Broad Line Regions (BLRs) are known to contain gravitationally-bound gas within r~(few) 10^2-10^3 Schwarszchild radii (Rs) near supermassive black holes (SMBHs) in Active Galactic…
Fractal signatures of non-Kerr spacetimes in the shadow of light-ring bifurcations
Konstantinos Kostaros, Padelis Papadopoulos, George Pappas
Light-ring bifurcations that can occur for prolate non-Kerr compact objects can leave an indelible signature on SMBH shadows as a fractal sequence of eyebrow-like formations. These…
