Related Progenitor Models for Long-duration Gamma-Ray Bursts and Type Ic Superluminous Supernovae [PDF]

open access: yes, 2018
We model the late evolution and mass loss history of rapidly rotating Wolf–Rayet stars in the mass range 5 M⊙…100 M⊙). We find that quasi-chemically homogeneously evolving single stars computed with enhanced mixing retain very little or no helium and are

Observational Constraints on the Progenitors of Core-Collapse Supernovae: The Case for Missing High-Mass Stars [PDF]

open access: yesPublications Astronomical Society of Australia, 2015
Over the last 15 years, the supernova community has endeavoured to directly identify progenitor stars for core-collapse supernovae discovered in nearby galaxies.

A Possible Solution to the Mystery of the ANITA Anomalous Events

open access: yesAnnalen der Physik, Volume 538, Issue 4, April 2026.
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

Constraining High-energy Neutrino Emission from Supernovae with IceCube

open access: yesThe Astrophysical Journal Letters, 2023
Core-collapse supernovae are a promising potential high-energy neutrino source class. We test for correlation between seven years of IceCube neutrino data and a catalog containing more than 1000 core-collapse supernovae of types IIn and IIP and a sample ...

A Central Excess of Stripped-Envelope Supernovae within Disturbed Galaxies

open access: yes, 2012
This paper presents an analysis of core-collapse supernova distributions in isolated and interacting host galaxies, paying close attention to the selection effects involved in conducting host galaxy supernova studies.

Slow-Speed Supernovae from the Palomar Transient Factory: Two Channels [PDF]

open access: yes, 2014
Since the discovery of the unusual prototype SN 2002cx, the eponymous class of low-velocity, hydrogen-poor supernovae has grown to include at most another two dozen members identified from several heterogeneous surveys, in some cases ambiguously. Here we

Establishing Indium in Frustrated Lewis Pair Chemistry: From Synthesis to Catalytic Applications

open access: yesChemistryEurope, Volume 4, Issue 4, April 2026.
Not that hard: The effects of chemical hardness of the soft FLP tBu2InCH2PtBu2 and its pyridine‐adduct tBu2In(py)CH2PtBu2 were examined in adduct formation reactions toward H2, CO2, and CS2. The frustrated Lewis pair shows catalytic activity in the reduction of CO2 with pinacolborane.

Validating the CROCODILE Model Within the AGORA Galaxy Simulation Framework

open access: yesGalaxies
Numerical galaxy formation simulations are sensitive to numerical methods and sub-grid physics models, making code comparison projects essential for quantifying uncertainties.

Neutrino Emission from Supernovae [PDF]

open access: yes, 2017
Supernovae are the most powerful cosmic sources of MeV neutrinos. These elementary particles play a crucial role when the evolution of a massive star is terminated by the collapse of its core to a neutron star or a black hole and the star explodes as ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.
