Discovery and Analysis of a Type II Supernova Candidate at z = 3.19 from JWST's COSMOS-Web Survey
Valeria Aparicio, David O. Jones, Willem B. Hoogendam +21
The launch of the James Webb Space Telescope (JWST) has enabled the discovery of a small but increasing sample of high-redshift core-collapse supernovae (CC SNe), which provide new…
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 case for super-Eddington accretion in JWST broad-line AGN during the first billion years
Erini Lambrides, Rebecca Larson, Kristen Garofali +23
A multitude of JWST studies reveal a surprising over-abundance of over-massive accreting super-massive black holes (SMBHs) -- leading to a deepening tension between theory and obse…
A broad-line quasar with unexplained extreme velocity offsets: post-shock outflow?
V. Rusakov, C. L. Steinhardt, M. Schramm +4
The quasar SDSS 0956+5128 exhibits three distinct velocity components with large offsets in emission: the systemic velocity of [O II], [O III] and [Ne III] narrow lines have redshi…
