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…
A sub-100 pc view at z~5 of a Multiply-Imaged Massive Quiescent Galaxy
Richard Pan, Danilo Marchesini, Joseph F. V. Allingham +34
Recent James Webb Space Telescope spectroscopic surveys reveal an abundance of rapidly assembled early galaxies in the first billion years. Cosmological simulations struggle to rep…
VENUS: an ultra-faint galaxy hosting the metal-poor type II supernova at Witnessing the initial metal enrichment with extremely frequent core-collapse supernovae?
Yoshihisa Asada, Seiji Fujimoto, Joseph F. V. Allingham +50
We present the first characterization of the host galaxy of a recently discovered type IIP SN at (SN Eos). SN Eos and its host galaxy are gravitationally lensed and multip…
Other red dots: A possible GLIMPSE of normal AGB stars at Cosmic Noon through extreme lensing
Lukas J. Furtak, Adi Zitrin, Erik Zackrisson +18
We report the discovery of four extremely faint () red point sources in recent ultra-deep JWST/NIRCam images of the strong lensing galaxy cluster Abell…
Two Exciting High-redshift Galaxy Candidates Turn Out to Be Two Exciting Ultra-cool Brown Dwarfs
Maruša Bradač, Chris Willott, Yoshihisa Asada +37
From the onset of observations of JWST we have discovered unexpectedly luminous galaxies at redshifts and as high as . With their discovery, the question immediately f…
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…
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…
