Similar or Different? Configurations of Authenticity Across Museum Types

Curator: The Museum Journal, EarlyView.
ABSTRACT Authenticity is traditionally regarded as playing a crucial role in museums, science centers, and memorials. However, despite this fact, authenticity has very different meanings in different (institutional) settings. This complicates shared communications across museum practices.

Axion fragmentation

Journal of High Energy Physics, 2020
We investigate the production of axion quanta during the early universe evolution of an axion-like field rolling down a wiggly potential. We compute the growth of quantum fluctuations and their back-reaction on the homogeneous zero-mode.

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field

Meteoritics &Planetary Science, EarlyView.
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Sun heated MeV-scale dark matter and the XENON1T electron recoil excess

Journal of High Energy Physics, 2021
The XENON1T collaboration reported an excess of the low-energy electron recoil events between 1 and 7 keV. We explore the possibility to explain such an anomaly by the MeV-scale dark matter (DM) heated by the interior of the Sun due to the same DM ...

Lonergan, Decolonization and First Nations Peoples: An Apologetic from an Insider on the Outside

Modern Theology, EarlyView.
Abstract The purpose of this article is to respond critically to a research project initiated out of the Board of the Lonergan Research Institute that seeks to expose colonialist assumptions in Lonergan's thought. Some of the initiatives seek to link Lonergan with complicity in Canadian residential schools, spiritual violence, and cultural genocide ...

Van Allen Probes Observations of a Fundamental Poloidal Wave in the Plasmasphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract All past spacecraft observations of fundamental poloidal Alfvén (P1) waves attributed to ion drift resonance have been made outside the plasmasphere. In this study, we present the first spacecraft observations of a plasmaspheric P1 wave driven by that resonance.

Real scalar dark matter: relativistic treatment

Journal of High Energy Physics, 2019
A stable real scalar provides one of the simplest possibilities to account for dark matter. We consider the regime where its coupling to the Standard Model fields is negligibly small.

Maximal axion misalignment from a minimal model

Journal of High Energy Physics, 2020
The QCD axion is one of the best motivated dark matter candidates. The misalignment mechanism is well known to produce an abundance of the QCD axion consistent with dark matter for an axion decay constant of order 1012 GeV.

Cancellation mechanism of dark matter direct detection in Higgs-portal and vector-portal models

Journal of High Energy Physics, 2022
We present two alternative proofs for the cancellation mechanism in the U(1) symmetric pseudo-Nambu-Goldstone-Boson Dark Matter (pNGB DM) model. They help us to have a better understanding of the mechanism from multi-angle, and inspire us to propose some

Reconnection Onset in Overstretched Thin Current Sheets: 3‐D Kinetic Picture

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract Evolution of the magnetotail equilibrium, whose current density iso‐contours are stretched beyond the magnetic field lines due to small ion anisotropy and agyrotropic effects on the scales of the thermal ion gyroradius (the so‐called overstretched thin current sheet) is considered using 3‐D explicit particle‐in‐cell simulations.
