Core Collapse Supernovae - 35 Years of Spectropolarimetry
, 2022 I will give a brief of overview of what spectropolarimetry has taught us about core collapse supernovae and stripped envelope supernovae, as well as highlight what I see as being the main challenges/issues that now need to be addressed to take us to the ...

Essential ingredients in core-collapse supernovae
AIP Advances, 2014 Carrying 1044 joules of kinetic energy and a rich mix of newly synthesized atomic nuclei, core-collapse supernovae are the preeminent foundries of the nuclear species which make up our solar system and ourselves.

Nuclei in core-collapse supernovae engine
Progress in Particle and Nuclear Physics, 2023 Herein, we review the nuclear equations of state (EOSs) %for core-collapse supernova simulations and the constituent nuclei of core-collapse supernovae (CCSNe) and their roles in CCSN simulations. Various nuclei such as deuterons, iron, and extremely neutron-rich nuclei compose in the central engines of CCSNe.

The Progenitor of the S147 Supernova Remnant
The Astrophysical JournalThe 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.

The Astrophysical JournalPresolar graphite grains carry the isotopic signatures of their parent stars. A significant fraction of presolar graphites show isotopic abundance anomalies relative to solar for elements such as O, Si, Mg, and Ca, which are compatible with ...

Bioethics, Volume 40, Issue 8, Page 793-807, October 2026.ABSTRACT This paper examines Israel's destruction and ‘humanitarianisation’ of Palestinian health systems, arguing that this should be understood as an instance of ‘necropolitics,’ as conceived by Achille Mbembe. We review the extensive, long‐term destruction of health systems in Palestine before 7 October 2023 and the catastrophic acceleration of that

Critical Conditions for Core-Collapse Supernovae [PDF]
Physical Review Letters, 2012 The explosion of a core-collapse supernova can be approximated by the breakdown of steady-state solutions for accretion onto a proto-neutron star (PNS). We analytically show that as the neutrino luminosity exceeds a critical value L_c, the neutrinosphere pressure exceeds the hydrostatic limit even for an optimal shock radius R.

Gravitational Radiation From Binary Systems With Time Varying Masses
Annalen der Physik, Volume 538, Issue 8, August 2026.We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

The Astrophysical JournalWe 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
