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…

Testing Lens Models of PLCK G165.7+67.0 Using Lensed SN H0pe

Aadya Agrawal, J. D. R. Pierel, Gautham Narayan +9

Supernova H0pe is a multiply-imaged Type Ia supernova (SN~Ia) and the second lensed SN to yield a measurement of the Hubble constant by the time-delay cosmography method, finding $…

Cosmology with supernova Encore in the strong lensing cluster MACS J0138-2155: Time delays & Hubble constant measurement

J. D. R. Pierel, E. E. Hayes, M. Millon +26

Multiply-imaged supernovae (SNe) provide a novel means of constraining the Hubble constant (). Such measurements require a combination of precise models of the lensing mass di…

Testing for Intrinsic Type Ia Supernova Luminosity Evolution at z>2 with JWST

J. D. R. Pierel, D. A. Coulter, M. R. Siebert +38

The James Webb Space Telescope} (JWST) is opening new frontiers of transient discovery and follow-up at high-redshift. Here we present the discovery of a spectroscopically confirme…

Lensed Type Ia Supernova "Encore" at z=2: The First Instance of Two Multiply-Imaged Supernovae in the Same Host Galaxy

J. D. R. Pierel, A. B. Newman, S. Dhawan +60

A bright (=24 mag), supernova (SN) candidate was discovered in JWST/NIRCam imaging acquired on 2023 November 17. The SN is quintuply-imaged as a result o…
