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…
The Hubble constant from strongly lensed supernovae with standardizable magnifications
Simon Birrer, Suhail Dhawan, Anowar J. Shajib
The dominant uncertainty in the current measurement of the Hubble constant () with strong gravitational lensing time delays is attributed to uncertainties in the mass profiles…
lenstronomy II: A gravitational lensing software ecosystem
Simon Birrer, Anowar J. Shajib, Daniel Gilman +18
lenstronomy is an Astropy-affiliated Python package for gravitational lensing simulations and analyses. lenstronomy was introduced by Birrer and Amara (2018) and is based on the li…
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_…
