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.

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

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

Molecular Ecology, Volume 35, Issue 19, October 2026.ABSTRACT The mechanisms driving the megadiversity of parasitic wasps remain a central question in evolutionary ecology. To investigate the genomic architecture underlying host‐associated differentiation in parasitic wasps, we generated a de novo genome assembly and performed whole‐genome re‐sequencing of 17 populations of the parasitoid wasp Asecodes ...

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.

Nuclear Weak Interactions in Core-Collapse Supernovae
, 2018 Core-collapse supernovae are one of the most fascinating phenomena in astrophysics,but the explosion mechanism is not clearly understood yet because of their intricacies. One underlying problem is the uncertainty in weak interaction rates. In particular,

The Astrophysical Journal, 2023 Previous numerical simulations of double-peaked Type IIb supernova (SN IIb) light curves have demonstrated that the radius and mass of the hydrogen-rich envelope of the progenitor star can significantly influence the brightness and timescale of the early-
