A new H_0 measurement with supernovae Requiem and Encore using Gravity.jl
We present a strong-lensing analysis of the galaxy cluster MACS J0138.0-2155 (z_ =0.336), the first known cluster lens discovered to host two distinct multiply imaged type Ia supernovae (SNe): SN Requiem and SN Encore. Both transients are located in the massive, multiply imaged red galaxy MRG-M0138 at z_ =1.949. The pr...
