SN Ares: A Strongly Lensed Type IIb Supernova at with a Predicted 70-Year Time Delay
Conor Larison, Justin D. R. Pierel, Matthew Siebert +69
We present the discovery of supernova (SN) Ares, a strongly lensed supernova at in a massive, triply imaged host galaxy behind the MACS J0308.9+2645 ga…
Can Blue UV-Bright Galaxies Drive Reionization at Cosmic Dawn? An Galaxy with at
Yunjing Wu, Sijia Cai, Yongda Zhu +28
We revisit EBG-1, a gravitationally lensed galaxy at , using newly obtained deep (14 hr) JWST/NIRSpec G235M () spectroscopy. EBG-1 is one of the bluest gala…
SN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3
Seiji Fujimoto, Conor Larison, Justin D. R. Pierel +64
We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at behind the galaxy cluster RXC J0018.5+162…
The Subversive Role of Excessive External Shear in Concealing Lensing Anomalies
Amruth Alfred, Shashpal Singh, Rommulus Francis Lewis +5
To best reproduce observed multiply-lensed lensed images, lens models usually incorporate shear attributed to objects unrelated to the lensing galaxy (i.e., external shear): whethe…
Little red dots as a cosmological probe: constraining with quasi-periodic pulsations
Zijian Zhang, Kohei Inayoshi, Masamune Oguri +4
The James Webb Space Telescope (JWST) has uncovered a population of ``little red dots'' (LRDs) at , potentially representing early supermassive black holes embedded in…
SN 2022riv in RX J2129: Discovery, Spectroscopic Classification, and Microlensing of a Strongly Lensed Type Ia Supernova from JWST and HST Observations
Birendra Dhanasingham, Patrick L. Kelly, Wenlei Chen +27
The multiply imaged SN 2022riv was discovered through a search of galaxy cluster fields as part of a Hubble Space Telescope (HST) SNAP program to find highly magnified stars. The s…
SLSim: a strong lensing population simulation package
Narayan Khadka, Simon Birrer, Henry Best +45
Gravitational lensing offers unique insights into cosmology by bending light around massive objects. Strong gravitational lensing, in particular, produces magnified and often multi…
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…
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…
VENUS: Two Faint Little Red Dots Separated by Hidden in a Single Lensed Galaxy at
Hiroto Yanagisawa, Masami Ouchi, Miriam Golubchik +47
We report the identification of a pair of faint little red dots (LRDs), dubbed Red Eyes, in a strongly-lensed galaxy at behind the PLCKG004.5-10.5 cluster, identified from…
