Searching for gravitationally lensed gamma-ray bursts with their afterglows
Sheng-Nan Chen, Xu-Dong Wen, He Gao +8
Gamma-ray bursts (GRBs) at high redshifts are expected to be gravitationally lensed by objects of different mass scales. Besides a single recent claim, no lensed GRB has been detec…
Identifying lensed quasars and measuring their time-delays from unresolved light curves
Satadru Bag, Arman Shafieloo, Kai Liao +1
Identifying multiply imaged quasars is challenging due to their low density in the sky and the limited angular resolution of wide field surveys. We show that multiply imaged quasar…
Finding quadruply imaged quasars with machine learning. I. Methods
A. Akhazhanov, A. More, A. Amini +68
Strongly lensed quadruply imaged quasars (quads) are extraordinary objects. They are very rare in the sky -- only a few tens are known to date -- and yet they provide unique inform…
Search for lensing signatures from the latest fast radio burst observations and constraints on the abundance of primordial black holes
Huan Zhou, Zhengxiang Li, Kai Liao +5
The possibility that primordial black holes (PBHs) form a part of dark matter has been considered for a long time but poorly constrained over a wide mass range. Fast radio bursts (…
Event rate predictions of strongly lensed gravitational waves with detector networks and more realistic templates
Lilan Yang, Shichao Wu, Kai Liao +5
Strong lensing of gravitational waves (GWs) is attracting growing attention of the community. The event rates of lensed GWs by galaxies were predicted in numerous papers, which use…
Improved time-delay lens modelling and inference with transient sources
Xuheng Ding, Kai Liao, Simon Birrer +3
Strongly lensed explosive transients such as supernovae, gamma-ray bursts, fast radio bursts, and gravitational waves are very promising tools to determine the Hubble constant ($H_…
