Kinematic Mapping of Giant Arcs: A New Method to Locate Lensing Critical Curves

Ruwen Zhou, Liang Dai, Lingyuan Ji +4

The vicinity of lensing critical curves features highly magnified portions of lensed galaxies. Accurate knowledge of the location and shape of the critical curve will be useful for…

VENUS: Strong-lensing model of MACS J1931.8-2635 -- revealing the farthest multiply imaged supernova

Joseph F. V. Allingham, Adi Zitrin, Vasily Kokorev +42

We present a parametric strong-lensing model for the galaxy cluster MACS J1931.8-2635 (), accompanying the detection of the spectroscopically confirmed SN Eos at $z = 5…

Testing Lens Models of PLCK G165.7+67.0 Using Lensed SN H0pe

Aadya Agrawal, J. D. R. Pierel, Gautham Narayan +9

Supernova H0pe is a multiply-imaged Type Ia supernova (SN~Ia) and the second lensed SN to yield a measurement of the Hubble constant by the time-delay cosmography method, finding $…

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…

A spectroscopically confirmed, strongly lensed, metal-poor Type II supernova at z = 5.13

David A. Coulter, Conor Larison, Justin D. R. Pierel +88

Observing supernovae (SNe) in the early Universe (z > 3) provides a window into how both galaxies and individual stars have evolved over cosmic time, yet a detailed study of high-r…
