Lens Modeling and Cosmological Inference from an Impure Sample of Galaxy-Galaxy Strong Lenses
Philip Holloway, Aprajita Verma, Philip J. Marshall +7
The start of the Legacy Survey of Space and Time marks a new era for strong lensing science, where the number of strong lenses identified is expected to increase to $\mathcal{O}(10…
ALPACA I: Controlling source and PSF systematics in JWST time-delay cosmography with differentiable lens modeling
Hrvoje Krizic, Martin Millon, Aymeric Galan +2
Time-delay cosmography provides an independent probe of the Hubble constant (), but exploiting the high-resolution imaging of the James Webb Space Telescope (JWST) requires st…
Strong Lensing Tomography: Double and pseudo multi-source plane strong gravitational lensing to constrain dark energy
Paras Sharma, Simon Birrer, Narayan Khadka +12
Tomographic measurements of gravitational lensing with different lens and source redshift distributions contain crucial information about the universe's relative expansion rate, an…
SLSim: a strong lensing population simulation package
Narayan Khadka, Simon Birrer, Henry Best +45
Gravitational lensing offers unique insights into cosmology by bending light around massive objects. Strong gravitational lensing, in particular, produces magnified and often multi…
Opportunities in AI/ML for the Rubin LSST Dark Energy Science Collaboration
LSST Dark Energy Science Collaboration, Eric Aubourg, Camille Avestruz +63
The Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will produce unprecedented volumes of heterogeneous astronomical data (images, catalogs, and alerts) that cha…
Investigating the Dark Energy Constraint from Strongly Lensed AGN at LSST-Scale
Sydney Erickson, Martin Millon, Padmavathi Venkatraman +12
Strongly lensed Active Galactic Nuclei (AGN) with an observable time delay can be used to constrain the expansion history of the Universe through time-delay cosmography (TDC). As t…
Lens Model Accuracy in the Expected LSST Lensed AGN Sample
Padmavathi Venkatraman, Sydney Erickson, Phil Marshall +13
Strong gravitational lensing of active galactic nuclei (AGN) enables measurements of cosmological parameters through time-delay cosmography (TDC). With data from the upcoming LSST…
A Data-Driven Prism: Multi-View Source Separation with Diffusion Model Priors
Sebastian Wagner-Carena, Aizhan Akhmetzhanova, Sydney Erickson
A common challenge in the natural sciences is to disentangle distinct, unknown sources from observations. Examples of this source separation task include deblending galaxies in a c…
Correcting for Selection Biases in the Determination of the Hubble Constant from Time-Delay Cosmography
Tian Li, Thomas E. Collett, Philip J. Marshall +4
The time delay between multiple images of strongly lensed quasars has been used to infer the Hubble constant. The primary systematic uncertainty for time-delay cosmography is the m…
Lens Modeling of STRIDES Strongly Lensed Quasars using Neural Posterior Estimation
Sydney Erickson, Sebastian Wagner-Carena, Phil Marshall +9
Strongly lensed quasars can be used to constrain cosmological parameters through time-delay cosmography. Models of the lens masses are a necessary component of this analysis. To en…
Time-Delay Cosmography: Measuring the Hubble Constant and other cosmological parameters with strong gravitational lensing
S. Birrer, M. Millon, D. Sluse +5
Multiply lensed sources experience a relative time delay in the arrival of photons. This effect can be used to measure absolute distances and the Hubble constant () and is kno…
