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…
Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy
Gregor Rihtaršič, Maruša Bradač, Guillaume Desprez +23
We present an updated gravitational lens model of the Bullet cluster (1E 0657-56) by combining JWST NIRCam imaging and NIRSpec spectroscopy. Although previous lens models relied on…
Strong Lensing by Galaxy Clusters
Priyamvada Natarajan, Liliya L. Williams, Marusa Bradac +4
Galaxy clusters as gravitational lenses play a unique role in astrophysics and cosmology: they permit mapping the dark matter distribution on a range of scales; they reveal the pro…
RELICS: A Very Large () Cluster Lens -- RXC J0032.1+1808
Ana Acebron, Adi Zitrin, Dan Coe +38
Extensive surveys with the \textit{Hubble Space Telescope} (HST) over the past decade, targeting some of the most massive clusters in the sky, have uncovered dozens of galaxy-clust…
Unveiling the Phase Transition of the Universe During the Reionization Epoch with Lyman-alpha
Steven L. Finkelstein, Marusa Bradac, Caitlin Casey +15
The epoch of reionization (6 < z < 10) marks the period in our universe when the first large galaxies grew to fruition, and began to affect the universe around them. Massive stars,…
Inferences on the Timeline of Reionization at z~8 From the KMOS Lens-Amplified Spectroscopic Survey
Charlotte A. Mason, Adriano Fontana, Tommaso Treu +12
Detections and non-detections of Lyman alpha (Ly) emission from galaxies ( Gyr after the Big Bang) can be used to measure the timeline of cosmic reionization. Of key i…
