The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
JWST MIRI flight performance: The Medium-Resolution Spectrometer
Ioannis Argyriou, Alistair Glasse, David R. Law +22
The Medium-Resolution Spectrometer (MRS) provides one of the four operating modes of the Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST). The MRS is a…
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…
Serendipitous detection of the dusty Type IIL SN 1980K with JWST/MIRI
Szanna ZsÃros, Tamás Szalai, Ilse De Looze +39
We present mid-infrared (mid-IR) imaging of the Type IIL supernova (SN) 1980K with the James Webb Space Telescope (JWST) more than 40 yr post-explosion. SN 1980K, located in the ne…
The JADES Transient Survey II: Volumetric Supernova Rates out to z~5
Christa DeCoursey, Christian Vassallo, Louis-Gregory Strolger +27
The paper uses JWST/NIRCam observations from the JADES Transient Survey to measure the first volumetric rates of core‑collapse and Type Ia supernovae at redshifts 2–5, employing ph…
The First Photometric Evidence of a Transient/Variable Source at z>5 with JWST
Christa DeCoursey, Eiichi Egami, Fengwu Sun +27
The James Webb Space Telescope (JWST) discovered 79 transients out to 4.8 through the JADES Transient Survey (JTS), but the JTS did not find any 5 transients. Here,…
Properties of high-redshift Type II supernovae discovered by the JADES transient survey
Takashi J. Moriya, David A. Coulter, Christa DeCoursey +23
In this work we estimate the explosion and progenitor properties of six Type II supernovae (SNe) at 0.675 <= z <= 3.61 discovered by the James Webb Space Telescope (JWST) Advanced…
Very Late-Time JWST and Keck Spectra of the Oxygen-Rich Supernova 1995N
Geoffrey C. Clayton, R. Wesson, Ori D. Fox +43
We present new {\it JWST}/MIRI MRS and Keck spectra of SN 1995N obtained in 2022--2023, more than 10,000 days after the supernova (SN) explosion. These spectra are among the latest…
JWST/MIRI detects the dusty SN1993J about 30 years after explosion
Tamás Szalai, Szanna ZsÃros, Jacob Jencson +37
Core-collapse supernovae (CCSNe) have long been considered to contribute significantly to the cosmic dust budget. New dust cools quickly and is therefore detectable at mid-infrared…
The JWST Discovery of the Triply-imaged Type Ia "Supernova H0pe" and Observations of the Galaxy Cluster PLCK G165.7+67.0
Brenda L. Frye, Massimo Pascale, Justin Pierel +39
A Type Ia supernova (SN) at was discovered in James Webb Space Telescope Near Infrared Camera imaging of the galaxy cluster PLCK G165.7+67.0 (G165; ). The SN is…
JWST MIRI flight performance: Detector Effects and Data Reduction Algorithms
Jane Morrison, Daniel Dicken, Ioannis Argyriou +21
The detectors in the Mid-Infrared Instrument (MIRI) of the James Webb Space Telescope (JWST) are arsenic-21 doped silicon impurity band conduction (Si:As IBC) devices and are direc…
The Science Performance of JWST as Characterized in Commissioning
Jane Rigby, Marshall Perrin, Michael McElwain +623
This paper characterizes the actual science performance of the James Webb Space Telescope (JWST), as determined from the six month commissioning period. We summarize the performanc…
JWST/MIRI Observations of Newly Formed Dust in the Cold, Dense Shell of the Type IIn SN 2005ip
Melissa Shahbandeh, Ori D. Fox, Tea Temim +42
Dust from core-collapse supernovae (CCSNe), specifically Type IIP SNe, has been suggested to be a significant source of the dust observed in high-redshift galaxies. CCSNe eject lar…
JWST Spectra Indicate a Large Mass of Postshock Dust Formed by SN 2010jl
Nathan Smith, Melissa Shahbandeh, Ori D. Fox +22
The paper reports JWST mid‑infrared spectra of the Type IIn supernova SN 2010jl 13 years after explosion, revealing a large (~0.2 M☉) mass of warm dust formed in the post‑shock reg…
