Polarimetry imprints of exotic compact objects: relativistic fluid spheres and gravastars
Hanna Liis Tamm, Nicolas Aimar, João Luís Rosa
Recent observations of polarimetric parameters of active galactic nuclei motivate the study of polarization in the spacetime of exotic compact objects which can mimic the features…
Sagittarius A* near-infrared flares polarization as a probe of space-time I: Non-rotating exotic compact objects
Nicolas Aimar, João Luís Rosa, Hanna Liis Tamm +1
The center of our galaxy hosts Sagittarius~A*, a supermassive compact object of solar masses, usually associated with a black hole. Nevertheless, black holes…
Polarimetry imprints of exotic compact objects: solitonic boson stars
João Luís Rosa, Nicolas Aimar, Hanna Liis Tamm
In this work we analyze the polarization observational properties of solitonic boson stars orbited by spherical hot-spots emitting synchrotron radiation from a thermal distribution…
Observational properties of hot-spots orbiting relativistic fluid spheres
Hanna Liis Tamm, João Luís Rosa
In this work we analyze the observational properties of relativistic fluid spheres when orbited by isotropically emitting sources, known as hot spots. We consider fluid star config…
