Broadened Lensing Rings of Compact Boson Stars: Enhanced Imprint of Accretion Flow in Images and Visibilities
Xiangyu Wang, Xinyu Wang, Minyong Guo +1
In this work, we systematically study the gravitational lensing properties and observational signatures of compact boson stars. Unlike black holes, the photon effective potential o…
Bayesian Analysis of Massive Boson Star Models for Sagittarius A* Using Near-Infrared Astrometry Data
Xiangyu Wang, Tian-chi Ma, Minyong Guo +1
Assuming that the compact source at the Galactic center, Sagittarius A*, is a massive boson star, we fit the near-infrared flare astrometry data. We consider 12 discrete boson star…
Testing solitonic boson star interpretations of Sagittarius A* with near-infrared flare astrometry
Xiangyu Wang, Zhenyu Zhang, Hai-Qing Zhang +2
We use GRAVITY near-infrared (NIR) flare astrometry to test whether Sagittarius A* could be a solitonic boson star. We consider five spherically symmetric solitonic boson-star mode…
Is a photon ring invariably a closed structure?
Xiangyu Wang, Xiaobao Wang, Hai-Qing Zhang +1
In this study, we investigate the image of a rotating compact object (CO) illuminated by a geometrically thin, optically thin disk on the equatorial plane. As the radius of the CO'…
How different are shadows of compact objects with and without horizons?
Xiangyu Wang, Yehui Hou, Minyong Guo
In this work, we theoretically assume that a compact object (CO) can have a dark surface so that the CO is simplified to have no emissions and reflections. Considering that the rad…
