Modeling lens potentials with continuous neural fields in galaxy-scale strong lenses
Luca Biggio, Georgios Vernardos, Aymeric Galan +1
Strong gravitational lensing is a unique observational tool for studying the dark and luminous mass distribution both within and between galaxies. Given the presence of substructur…
Using wavelets to capture deviations from smoothness in galaxy-scale strong lenses
Aymeric Galan, Georgios Vernardos, Austin Peel +2
Modeling the mass distribution of galaxy-scale strong gravitational lenses is a task of increasing difficulty. The high-resolution and depth of imaging data now available render si…
Gravitationally lensed quasars in Gaia -- IV. 150 new lenses, quasar pairs, and projected quasars
C. Lemon, T. Anguita, M. Auger +8
We report the spectroscopic follow-up of 175 lensed quasar candidates selected using Gaia Data Release 2 observations following Lemon et al. 2019. Systems include 86 confirmed lens…
Lightweight HI source finding for next generation radio surveys
Emma Tolley, Damien Korber, Aymeric Galan +5
Future deep HI surveys will be essential for understanding the nature of galaxies and the content of the Universe. However, the large volume of these data will require distributed…
TDCOSMO. IX. Systematic comparison between lens modelling software programs: time delay prediction for WGD 2038-4008
A. J. Shajib, K. C. Wong, S. Birrer +15
The importance of alternative methods for measuring the Hubble constant, such as time-delay cosmography, is highlighted by the recent Hubble tension. It is paramount to thoroughly…
