Microlensing of strongly lensed quasars
G. Vernardos, D. Sluse, D. Pooley +9
Strong gravitational lensing of quasars has the potential to unlock the poorly understood physics of these fascinating objects, as well as serve as a probe of the lensing mass dist…
NANCY: Next-generation All-sky Near-infrared Community surveY
Jiwon Jesse Han, Arjun Dey, Adrian M. Price-Whelan +206
The Nancy Grace Roman Space Telescope is capable of delivering an unprecedented all-sky, high-spatial resolution, multi-epoch infrared map to the astronomical community. This oppor…
Strong gravitational lensing by AGNs as a probe of the quasar-host relations in the distant Universe
Martin Millon, Frédéric Courbin, Aymeric Galan +4
The tight correlations found between masses of supermassive black holes (SMBHs) and the luminosities, total stellar masses, and velocity dispersions of their host galaxies are ofte…
STARRED: a two-channel deconvolution method with Starlet regularization
Kevin Michalewicz, Martin Millon, Frédéric Dux +1
The spatial resolution of astronomical images is limited by atmospheric turbulence and diffraction in the telescope optics, resulting in blurred images. This makes it difficult to…
The Magnificent Five Images of Supernova Refsdal: Time Delay and Magnification Measurements
Patrick L. Kelly, Steven Rodney, Tommaso Treu +28
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…
Constraints on the Hubble constant from Supernova Refsdal's reappearance
Patrick L. Kelly, Steven Rodney, Tommaso Treu +27
The gravitationally lensed Supernova Refsdal appeared in multiple images, produced through gravitational lensing by a massive foreground galaxy cluster. After the supernova appeare…
Probing compact dark matter objects with microlensing in gravitationally lensed quasars
Petra Awad, James H. H. Chan, Martin Millon +2
The microlensing signal in the light curves of gravitationally lensed quasars can shed light on the dark matter (DM) composition in their lensing galaxies. Here, we investigate a s…
Peculiar velocity effects on the Hubble constant from time-delay cosmography
Charles Dalang, Martin Millon, Tessa Baker
Two major challenges of contemporary cosmology are the Hubble tension and the cosmic dipole tension. At the crossroad of these, we investigate the impact of peculiar velocities on…
The impact of human expert visual inspection on the discovery of strong gravitational lenses
Karina Rojas, Thomas E. Collett, Daniel Ballard +53
We investigate the ability of human 'expert' classifiers to identify strong gravitational lens candidates in Dark Energy Survey like imaging. We recruited a total of 55 people that…
