Chromatic Microlensing Time Delays
Kai Liao
Due to the finite size of the disk and the temperature fluctuations producing the variability, microlensing changes the actual time delays between images of strongly lensed AGN on…
Impact of Microlensing on Observational Strategies for Gravitational Time Delay Measurements
Kai Liao
Microlensing not only brings extra magnification lightcurves on top of the intrinsic ones but also shifts them in time domain, making the actual time-delays between images of stron…
Constraints on compact dark matter with fast radio burst observations
Kai Liao, S. -B. Zhang, Zhengxiang Li +1
Fast Radio Bursts (FRBs) are bright radio transients with millisecond duration at cosmological distances. Since compact dark matter/objects (COs) could act as lenses and cause spli…
Multiple measurements of quasars acing as standard probes: exploring the cosmic distance duality relation at higher redshift
Xiaogang Zheng, Kai Liao, Marek Biesiada +3
General relativity reproduces main current cosmological observations, assuming the validity of cosmic distance duality relation (CDDR) at all scales and epochs. However, CDDR is po…
Black hole mass function and its evolution -- the first prediction for the Einstein Telescope
Xuheng Ding, Kai Liao, Marek Biesiada +1
The knowledge about the black hole mass function (BHMF) and its evolution would help to understand the origin of the BHs and how BH binaries formed at different stages of the histo…
Determining Model-independent and Consistency Tests
Kai Liao, Arman Shafieloo, Ryan E. Keeley +1
We determine the Hubble constant precisely ( uncertainty) in a manner independent of cosmological model through Gaussian process regression, using strong lensing and s…
