Supernova 2025wny: High-angular resolution Keck/NIRC2 observations and preliminary lens modeling

Christopher J. Storfer, Kenneth C. Wong, Ana Acebron +10

Multiply imaged, gravitationally lensed supernovae are rare but powerful tools for providing independent measurements on cosmological parameters. Supernova (SN) 2025wny ("SN Winny"…

Strong Lensing Model and Dust Extinction Maps of the Host Galaxy of Type Ia Supernova H0pe

A. Galan, S. Schuldt, G. B. Caminha +11

Strong gravitational lensing by massive galaxy clusters offers rare opportunities to observe multiple images of distant () Type Ia supernovae (SNe) and to resolve the…

Cluster-lensed supernova yields from the Vera C. Rubin Observatory and Nancy Grace Roman Space Telescope

M. Bronikowski, T. Petrushevska, J. D. R. Pierel +5

Through gravitational lensing, galaxy clusters can magnify supernovae (SNe) and create multiple images of the same SN. This enables measurements of cosmological parameters, which w…

A new quasar strongly-lensed candidate by the galaxy cluster WHJ0400-27 with a image-separation

L. Bazzanini, G. Angora, M. Scialpi +14

Time-delay cosmography (TDC) using multiply-lensed quasars (QSOs) by galaxies has recently emerged as an independent and competitive tool to measure the value of the Hubble constan…

Enhanced strong-lensing model of MACS~J0138.02155 based on new JWST and VLT/MUSE observations

Ana Acebron, Pietro Bergamini, Piero Rosati +10

We present a new parametric strong lensing analysis of the galaxy cluster MACS J0138.0-2155 at z = 0.336, the first known to show two multiply-imaged supernova (SN) siblings, SN Re…

Cosmology with Supernova Encore in the lensing cluster MACS J01382155 -- Spectroscopy with MUSE

G. Granata, G. B. Caminha, S. Ertl +9

We present a spectroscopic analysis of MACS J01382155, at , the first galaxy cluster hosting two strongly-lensed supernovae (SNe), Requiem and Encore, providing us with…
