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…
Probing Physics Beyond the Standard Model through Combined Analyses of Next-Generation Type Ia Supernova, CMB, and BAO Surveys
Srinivasan Raghunathan, Ayan Mitra, Nikolina Å arÄeviÄ +11
Observations of Type Ia supernovae (\sne), which probe the late Universe, together with baryon acoustic oscillations (BAO) and the cosmic microwave background (CMB), which probe th…
Toward testing gravity with LSST using
C. D. Leonard, S. Alam, R. Mandelbaum +4
is a summary statistic that combines cosmological observables to achieve a test of gravity that is relatively model-independent. Here, we consider the power of a measurement…
Halo Occupation Distribution estimation performance for LSST data
P. Cataldi, V. Cristiani, F. Rodriguez +4
Upcoming imaging surveys, such as the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), will enable high signal-to-noise measurements of galaxy clustering. The halo…
A halo model approach for mock catalogs of time-variable strong gravitational lenses
Katsuya T. Abe, Masamune Oguri, Simon Birrer +5
Time delays in both galaxy- and cluster-scale strong gravitational lenses have recently attracted a lot of attention in the context of the Hubble tension. Future wide-field cadence…
