New Arabic Records From Cairo on Supernovae 1181 and 1006

Astronomische Nachrichten, Volume 346, Issue 9, November 2025.
ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

A New Monte Carlo Method for Time-Dependent Neutrino Radiation Transport [PDF]

, 2012
Monte Carlo approaches to radiation transport have several attractive properties compared to deterministic methods. These include simplicity of implementation, high accuracy, and good parallel scaling.

SN 2020bio: A Double-peaked, H-poor Type IIb Supernova with Evidence of Circumstellar Interaction

The Astrophysical Journal, 2023
We present photometric and spectroscopic observations of SN 2020bio, a double-peaked Type IIb supernova (SN) discovered within a day of explosion, primarily obtained by Las Cumbres Observatory and Swift.

First Detection of [SI] in Near‐IR JWST Observations of Io in Eclipse, and Comparison With SO Emissions, Evolving Volcanic Eruptions, and Prior UV HST‐STIS [SI] Emissions

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract We observed Io with the James Webb Space Telescope (JWST) NIRSpec/Integral Field Unit (1.0–5.3 μm, R∼2700 $R\sim 2700$) in August 2023 while the satellite was in eclipse. Thermal emission from Kanehekili Fluctus is consistent with the cooling of lava flows after a vigorous eruption in November 2022.

Using Nebular Near-infrared Spectroscopy to Measure Asymmetric Chemical Distributions in 2003fg-like Thermonuclear Supernovae

The Astrophysical Journal
We present an analysis of three near-infrared (NIR; 1.0–2.4 μ m) spectra of the SN 2003fg–like/“super-Chandrasekhar” Type Ia supernovae (SNe Ia) SN 2009dc, SN 2020hvf, and SN 2022pul at respective phases of +372, +296, and +294 days relative to the epoch

Spectropolarimetry of Core-Collapse Supernovae [PDF]

, 2004
We briefly review the young field of spectropolarimetry of core-collapse supernovae (SNe). Spectropolarimetry provides the only direct known probe of early-time supernova (SN) geometry.

Explosive nucleosynthesis in core-collapse supernovae

, 2010
The specific mechanism and astrophysical site for the production of half of the elements heavier than iron via rapid neutron capture (r-process) remains to be found.

The Innermost Ejecta of Core Collapse Supernovae [PDF]

, 2004
We ensure successful explosions (of otherwise non-explosive models) by enhancing the neutrino luminosity via reducing the neutrino scattering cross sections or by increasing the heating efficiency via enhancing the neutrino absorption cross sections in ...

The Progenitor of the S147 Supernova Remnant

The Astrophysical Journal
The supernova remnant (SNR) S147 contains the pulsar PSR J0538+2817 and a likely unbound binary companion, HD 37424. It is the only good Galactic candidate for a binary unbound by a core-collapse supernova.

A Flight Back to Ground: Jung’s Recalcitrant Fourth as Rape into Consciousness. Symbolic Rape and Literal Rape in Persephone’s Myth

Journal of Analytical Psychology, Volume 70, Issue 4, Page 616-639, September 2025.
Abstract Patricia Berry’s interpretation of the Demeter/Persephone myth, and her concept of rape into consciousness, illuminate intrapsychic dynamics. However, this symbolic lens may inadvertently distance us from the devastating nature of literal rape—a reality the Homeric Hymn encapsulates.
