Projected Cosmological Constraints from Strongly Lensed Supernovae with the Roman Space Telescope
J. D. R. Pierel, S. Rodney, G. Vernardos +3
One of the primary mission objectives for the Roman Space Telescope is to investigate the nature of dark energy with a variety of methods. Observations of Type Ia supernovae (SNIa)…
Survey of Gravitationally lensed Objects in HSC Imaging (SuGOHI) -- VII. Discovery and Confirmation of Three Strongly Lensed Quasars
Anton T. Jaelani, Cristian E. Rusu, Issha Kayo +13
We present spectroscopic confirmation of three new two-image gravitationally lensed quasars, compiled from existing strong lens and X-ray catalogs. Images of HSC J091843.2702200…
TDCOSMO II: 6 new time delays in lensed quasars from high-cadence monitoring at the MPIA 2.2m telescope
M. Millon, F. Courbin, V. Bonvin +25
We present six new time-delay measurements obtained from -band monitoring data acquired at the Max Planck Institute for Astrophysics (MPIA) 2.2 m telescope at La Silla observa…
A Quasar Microlensing Light Curve Generator for LSST
Favio Neira, Timo Anguita, Georgios Vernardos
We present a tool to generate mock quasar microlensing light curves and sample them according to any observing strategy. An updated treatment of the fixed and random velocity compo…
STRIDES: Spectroscopic and photometric characterization of the environment and effects of mass along the line of sight to the gravitational lenses DES J0408-5354 and WGD 2038-4008
E. J. Buckley-Geer, H. Lin, C. Rusu +65
In time-delay cosmography, three of the key ingredients are 1) determining the velocity dispersion of the lensing galaxy, 2) identifying galaxies and groups along the line of sight…
