Cosmic abundances of SIMP dark matter
Journal of High Energy Physics, 2017 Thermal production of light dark matter with sub-GeV scale mass can be attributed to 3 → 2 self-annihilation processes. We consider the thermal average for annihilation cross sections of dark matter at 3 → 2 and general higher-order interactions.

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.

The Structure and Interpretation of Cosmology [PDF]
, 2003 The purpose of this paper is to review, clarify, and critically analyse modern mathematical cosmology. The emphasis is upon the mathematical structures involved, rather than numerical computations.

Developing World Bioethics, EarlyView.ABSTRACT Mental privacy is a growing concern as neurotechnologies and digital mental health tools collect and process sensitive brain‐related data. In South Africa, cultural and religious diversity adds complexity to protecting mental privacy, with traditional healing practices, communal decision‐making, and spiritual beliefs influencing mental health ...

How (Not) to Take ‘Secularity’ Beyond the Modern West: Reflections from Islamic Sociology [PDF]
, 2019 Debates about the usability of the concept of ‘secularity’ in academic research are not merely theoretical. Standpoints are also politically informed and arguments are sometimes emotionally charged.

Under-determination in Cosmology: an Invitation [PDF]
, 2012 I discuss how modern cosmology illustrates under-determination of theoretical hypotheses by data, in ways that are different from most philosophical discussions.

Relaxion fluctuations (self-stopping relaxion) and overview of relaxion stopping mechanisms
Journal of High Energy Physics, 2020 In implementations of the electroweak scale cosmological relaxation mechanism proposed so far, the effect of the quantum fluctuations of the homogeneous relaxion field has been ignored.

Detecting dark photons from atomic rearrangement in the galaxy
Journal of High Energy Physics, 2021 We study a new dark sector signature for an atomic process of “rearrangement” in the galaxy. In this process, a hydrogen-like atomic dark matter state together with its anti-particle can rearrange to form a highly-excited bound state.

Bolide Light Curve Systematics from 75 Recovered Meteorites
Meteoritics &Planetary Science, EarlyView.Abstract How does the energy deposition profile (light curve), deceleration, and penetration depth in Earth's atmosphere depend on asteroid composition and meteorite type? Here, we present the light curve and velocity profile of 75 bolides from camera‐documented meteorite falls.
