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"…
A boost in the precision of cluster-mass models: Exploiting the extended surface brightness of the lensed supernova Refsdal host galaxy
S. Schuldt, C. Grillo, A. Acebron +4
Combining deep Hubble Space Telescope (HST) images and extensive data from the Multi-Unit Spectroscopic Explorer, we present new mass models of the cluster MACS J1149.5+2223, stron…
Non-spherical BUFFALOs: a weak lensing view of the Frontier Field clusters and associated systematics
A. Niemiec, A. Acebron, B. Beauchesne +15
Galaxy clusters are tracers of the large scale structures of the Universe, making the time evolution of their mass function dependent on key cosmological parameters, such as the co…
