Simple method of diagnosing fast flavor conversions of supernova neutrinos [PDF]
Physical Review D, 2018 Neutrinos emitted from a supernova may undergo flavor conversions almost immediately above the core, with possible consequences for supernova dynamics and nucleosynthesis.

Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie
Physik in unserer Zeit, EarlyView.Im Jahr 1989 hat das Wipple‐Observatorium die erste Quelle hochenergetischer Gammastrahlung entdeckt. 2002 waren dann sechs Quellen bekannt, 2024 schon mehr als 300. Und das ist immer noch lediglich die Spitze des Eisbergs in der jungen Geschichte der Gammaastronomie.

The Observer's Guide to the Gamma-Ray Burst-Supernova Connection [PDF]
, 2016 We present a detailed report of the connection between long-duration gamma-ray bursts (GRBs) and their accompanying supernovae (SNe). The discussion presented here places emphasis on how observations, and the modelling of observations, have constrained ...

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 ...

Examining Neutrino–Matter Interactions in the Cassiopeia A Supernova
The Astrophysical Journal, 2023 Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confirm observationally.

The Carnegie Supernova Project. I. Third Photometry Data Release of Low-redshift Type Ia Supernovae and Other White Dwarf Explosions [PDF]
, 2017 We present final natural-system optical (ugriBV) and near-infrared (YJH) photometry of 134 supernovae (SNe) with probable white dwarf progenitors that were observed in 2004–2009 as part of the first stage of the Carnegie Supernova Project (CSP-I).

Formation of Uranium Pinacolate from the Reductive Coupling of Acetone
Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.Uranium(III) cyclopentadienyl complexes are shown to react with acetone in a pinacol coupling, forming uranium pinacolate complexes. Single crystals obtained from the reaction are the first direct structural proof of the previously proposed metallapinacolate intermediate. 1,2‐Diols are elemental building blocks in organic synthesis.

Star Formation as Seen by Low Mass Stars
Acta Polytechnica CTU Proceedings, 2014 Using the Hubble Space Telescope (HST) we have characterised and compared the physical properties of a large sample of pre-main sequence (PMS) stars spanning a wide range of masses (0:5 - 4Mʘ), metallicities (0:1 - 1 Zʘ) and ages (0:5 - 30 Myr).
