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 unusual planetary nebula nucleus in the Galactic open cluster M37 and six further hot white dwarf candidates
Klaus Werner, Nicole Reindl, Roberto Raddi +6
Planetary nebulae in Galactic open star clusters are rare objects; only three are known to date. They are of particular interest because their distance can be determined with high…
Revisiting the Mass Step: Environmental Dependence of Type Ia Supernovae in Low-Metallicity Host Galaxies
Estefania Padilla Gonzalez, A. Joshi Bhavin, Louis G. Strolger +14
Despite the tremendous impact of Type Ia supernovae (SNe Ia) on the field of cosmology, their underlying physics are still poorly understood. Studies have found an intriguing corre…
A Long Period Stellar-Mass Black Hole Binary in Centauri
Matthew Whitaker, Evan Kerr, Anil Seth +16
Modern simulations of stellar dynamics in globular clusters peg a dominant role for stellar-mass black holes, but direct evidence for black holes in clusters remains limited. We pr…
Expanding the High-z Supernova Frontier: "Wide-Area" JWST Discoveries from the First Two Years of COSMOS-Web
Ori D. Fox, Armin Rest, Justin D. R. Pierel +48
Transient astronomy in the early Universe (z > 2) remains largely unexplored, lying beyond the rest-frame optical spectroscopic reach of most current observatories. Yet this regime…
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…
