One possible explanation for the Balmer and Lyman line shifts in quasars
Dangbo Liu, Jianrong Shi, Junhan You
Internal line shifts in quasars spectra have played a more prominent role in our understanding of quasar structure and dynamics. The observed different redshift among broad hydroge…
X-ray spectropolarimetric signature of a warped disk around a stellar-mass black hole
Yifan Cheng, Dan Liu, Sourabh Nampalliwar +1
Black holes in X-ray binaries are often assumed to be rotating perpendicular to the plane of the accretion disk and parallel to the orbital plane of the binary. While the Bardeen-P…
X-ray spectropolarimetric measurements of the Kerr metric
Dan Liu, Zilong Li, Yifan Cheng +1
It is thought that the spacetime geometry around black hole candidates is described by the Kerr solution, but an observational confirmation is still missing. Today, the continuum-f…
Testing a class of non-Kerr metrics with hot spots orbiting SgrA
Dan Liu, Zilong Li, Cosimo Bambi
SgrA, the supermassive black hole candidate at the Galactic Center, exhibits flares in the X-ray, NIR, and sub-mm bands that may be interpreted within a hot spot model. Light c…
A two-component jet model for the tidal disruption event Swift J164449.3+573451
Dangbo Liu, Asaf Pe'er, Abraham Loeb
We analyze both the early and late time radio and X-ray data of the tidal disruption event Swift J1644+57. The data at early times ( days) necessitates separation of th…
