Narrowing down the Hubble constant value by exploiting the extended surface brightness of the supernova Refsdal host galaxy
S. Schuldt, C. Grillo, S. H. Suyu +7
We present the first inference of the Hubble constant and matter density parameter from a strongly lensed supernova by exploiting the mass model of a galaxy cluster enhanced by an…
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…
GPU-Accelerated Gravitational Lensing & Dynamical (GLaD) Modeling for Cosmology and Galaxies
Han Wang, Sherry H. Suyu, Aymeric Galan +4
Time-delay distance measurements from strongly lensed quasars provide a robust, independent method for determining the Hubble constant (). This approach cross-checks est…
Cosmology with supernova Encore in the strong lensing cluster MACS J01382155: photometry, cluster members, and lens mass model
S. Ertl, S. H. Suyu, S. Schuldt +23
The strongly lensed Supernova (SN) Encore at a redshift of , discovered behind the galaxy cluster MACS J01382155 at , provides a rare opportunity for time-de…
HOLISMOKES -- X. Comparison between neural network and semi-automated traditional modeling of strong lenses
S. Schuldt, S. H. Suyu, R. Canameras +4
Modeling of strongly gravitationally lensed galaxies is often required in order to use them as astrophysical or cosmological probes. With current and upcoming wide-field imaging su…
On the accuracy of time-delay cosmography in the Frontier Fields Cluster MACS J1149.5+2223 with supernova Refsdal
C. Grillo, P. Rosati, S. H. Suyu +3
We study possible systematic effects on the values of the cosmological parameters measured through strong lensing analyses of the HFF galaxy cluster MACS J1149.5+2223. We use the o…
