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 (H0​). Such measurements require a combination of precise models of the lensing mass di…

Cosmology with supernova Encore in the strong lensing cluster MACS J0138-2155: Lens model comparison and H0 measurement

S. H. Suyu, A. Acebron, C. Grillo +28

MACS J0138-2155 is the only known cluster to strongly lens two supernovae (SNe), Requiem and Encore, from the same host galaxy at z=1.949. We present seven independent mass models…

Ground-based parallax confirmed by Spitzer: binary microlensing event MOA-2015-BLG-020

Tianshu Wang, Wei Zhu, Shude Mao +83

We present the analysis of the binary gravitational microlensing event MOA-2015-BLG-020. The event has a fairly long timescale (about 63 days) and thus the light curve deviates sig…
