A Significant Dust Reservoir Uncovered with JWST in the Type Ic SN 1983V More Than 40 Years Post-Explosion
Sophia S. Kressy, Thomas Moore, Ori D. Fox +26
Searching for late-time emission from supernovae (SNe) is an active field. Infrared (IR) wavelengths are sensitive to thermal emission from dust, which can be used to probe SN cont…

Presaging Doppler beaming discoveries of double white dwarfs during the Rubin LSST era
Gautham Adamane Pallathadka, Yossef Zenati, Nadia L. Zakamska +2
Double white dwarfs (DWDs) are by far the most common compact binaries in the Milky Way, are important low-frequency gravitational-wave sources, and in some cases merge to become T…
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 Structure of Poloidal Fields Embedded in Thin Disks
Yossef Zenati, Ethan T. Vishniac, Amir Jafari
Many accreting systems are modeled as geometrically thin disks. Simulations of accretion disks cannot be extended to this regime, although local models can address the behavior of…
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…
SN 2025ogs: A Spectroscopically-Normal Type Ia Supernova at z = 2 as a Benchmark for Redshift Evolution

The Nancy Grace Roman Space Telescope will provide a revolutionary measurement of the Universe's expansion kinematics, driven by dark matter and dark energy, out to .…
SN 2019vxm: A Shocking Coincidence between Fermi and TESS
Zachary G. Lane, Ryan Ridden-Harper, Sofia Rest +37
Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in T…
Neutrino diagnostics of hadron-quark phase transition in Neutron Stars
Yossef Zenati, Conrado Albertus Torres, Joseph Silk +1
We investigate neutrino signatures of a hadron-quark phase transition (HQPT) in neutron stars (NS) leading to quark star (QS) formation. We use representative hadronic and quark eq…
