We present a free-form model of SMACS0723, the first cluster observed with JWST. This model does not make any strong assumptions on the distribution of mass (mostly made up of dark matter) in the cluster and we use it to study the possible correlatio...

In late 2014, four images of supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149 galaxy-cluster field. Following the images' discovery, the SN was predicted to reapp... Read More about The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements.

On the gravitational lensing interpretation of three gravitational wave detections in the mass gap by LIGO and Virgo (2023)
Journal Article

On the gravitational lensing interpretation of three gravitational wave detections in the mass gap by LIGO and Virgo. Monthly Notices of the Royal Astronomical Society, 521(3), 3421-3430. https://doi.org/10.1093/mnras/stad673

We search for gravitational wave (GW) events from LIGO-Virgo’s third run that may have been affected by gravitational lensing. Gravitational lensing delays the arrival of GWs, and alters their amplitude – thus biasing the inferred progenitor masses....
