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…
The Cosmic Evolution Early Release Science Survey (CEERS)
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +96
We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hour Director's Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates e…
LensWatch. II. Improved Photometry and Time-delay Constraints on the Strongly Lensed Type Ia Supernova 2022qmx ("SN Zwicky") with HST Template Observations
Conor Larison, Justin D. R. Pierel, Max J. B. Newman +34
Strongly lensed supernovae (SNe) are a rare class of transient that can offer tight cosmological constraints that are complementary to methods from other astronomical events. We pr…
Spectroscopic analysis of the strongly lensed SN~Encore: Constraints on cosmic evolution of Type Ia supernovae
S. Dhawan, J. D. R. Pierel, M. Gu +16
Strong gravitational lensing magnifies the light from a background source, allowing us to study these sources in detail. Here, we study the spectra of a lensed Type Ia s…
Lensed Type Ia Supernova "Encore" at z=2: The First Instance of Two Multiply-Imaged Supernovae in the Same Host Galaxy
J. D. R. Pierel, A. B. Newman, S. Dhawan +60
A bright (=24 mag), supernova (SN) candidate was discovered in JWST/NIRCam imaging acquired on 2023 November 17. The SN is quintuply-imaged as a result o…
JWST Spectroscopy of SN H0pe: Classification and Time Delays of a Triply-imaged Type Ia Supernova at z = 1.78
Wenlei Chen, Patrick L. Kelly, Brenda L. Frye +19
SN H0pe is a triply imaged supernova (SN) at redshift discovered using the James Webb Space Telescope (JWST). In order to classify the SN spectroscopically and measure the…
JWST Photometric Time-Delay and Magnification Measurements for the Triply-Imaged Type Ia "Supernova H0pe" at z = 1.78
J. D. R. Pierel, B. L. Frye, M. Pascale +60
Supernova (SN) H0pe is a gravitationally lensed, triply-imaged, Type Ia SN (SN Ia) discovered in James Webb Space Telescope imaging of the PLCK G165.7+67.0 cluster of galaxies. Wel…
The Foundation Supernova Survey: Motivation, Design, Implementation, and First Data Release
Ryan J. Foley, Daniel Scolnic, Armin Rest +25
The Foundation Supernova Survey aims to provide a large, high-fidelity, homogeneous, and precisely-calibrated low-redshift Type Ia supernova (SN Ia) sample for cosmology. The calib…
Deja Vu All Over Again: The Reappearance of Supernova Refsdal
P. L. Kelly, S. A. Rodney, T. Treu +21
In Hubble Space Telescope (HST) imaging taken on 10 November 2014, four images of supernova (SN) "Refsdal" (redshift z=1.49) appeared in an Einstein-cross--like configuration (imag…
ASASSN-15lh: A Highly Super-Luminous Supernova
Subo Dong, B. J. Shappee, J. L. Prieto +27
We report the discovery of ASASSN-15lh (SN 2015L), which we interpret as the most luminous supernova yet found. At redshift z = 0.2326, ASASSN-15lh reached an absolute magnitude of…
