Superluminous Supernovae [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractNot long ago the sample of well studied supernovae, which were gathered mostly through targeted surveys, was populated exclusively by events with absolute peak magnitudes fainter than about −20. Modern searches that select supernovae not just from massive hosts but from dwarfs as well have produced a new census with a surprising difference: a ...

Hamas's October 7 Attack: Analysis of an “Antagonistic” Crisis
Public Administration Review, EarlyView.ABSTRACT The aim of the article is to interpret the Hamas attack of October 7, 2023 in light of crisis management theories, seeking to draw from this event some general lessons about the nature of crises, their determinants, and how they are managed. More specifically, the article addresses three questions: (1) Why did Israel underestimate the warning ...

Risk Analysis, EarlyView.Abstract There are two separate conceptualizations for assessing existential risks: Planetary Boundaries (PBs) and global catastrophic risks (GCRs). While these concepts are similar in principle, their underpinning literatures tend not to engage with each other.

Red Supergiants as Supernova Progenitors
GalaxiesThe inevitable fate of massive stars in the initial mass range of ≈8–30M⊙ in the red supergiant (RSG) phase is a core-collapse supernova (SN) explosion, although some stars may collapse directly to a black hole.

Whole genome shotgun phylogenomics resolve the diving beetle tree of life
Systematic Entomology, EarlyView.A new and strongly supported phylogeny of diving beetles (Dytiscidae) is presented using the largest genomic dataset to date. Laccophilinae and Coptotominae + Lancetinae are early diverging lineages excluded from a large monophyletic clade comprising the remaining eight subfamilies. We identify seven remaining problems in the backbone of the phylogeny,

Explosive nucleosynthesis and beyond: Energy generation in supernovae from massive progenitors [PDF]
EPJ Web of ConferencesMassive stars (initial mass ≳10M⊙, where M⊙ is the mass of the Sun) end their life through violent explosions known as core-collapse supernovae, which are supposed to be among the brightest events of the universe.

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Science, 2007 Analysis of the polarization of light from supernovae can reveal the shape and distribution of matter ejected from exploding stars. Here we review the young field of Type Ia supernova spectropolarimetry and critically evaluate, and place in context, the recent work of Wang et al.

Molecular Ecology, Volume 34, Issue 15, August 2025.Abstract Natural variation can provide important insights into the genetic and environmental factors that shape social behaviour and its evolution. The sweat bee, Lasioglossum baleicum, is a socially flexible bee capable of producing both solitary and eusocial nests.
