Polarized Emission from Gamma-Ray Burst Jets

open access: yesGalaxies, 2017
I review how polarization signals have been discussed in the research field of Gamma-Ray Bursts (GRBs). I mainly discuss two subjects in which polarimetry enables us to study the nature of relativistic jets.

Powers That Be: An Adventure in Metaphysics

open access: yesPhilosophical Investigations, EarlyView.
ABSTRACT This paper is an investigation into the increasingly popular trend amongst philosophers on the metaphysics of powers, exemplified by the statement: ‘To be real is to possess a power to affect (or to be affected by) other things’. First, I briefly trace the history of this idea (from the Eleatic dialectic of ancient times to present day quantum

Dreams, Scepticism and Idealism

open access: yesTheoria, EarlyView.
ABSTRACT On one narrative, Berkeleyan idealism arises from Cartesian theorising: Descartes's discussion of dreaming in the Meditations leads first to scepticism, and through scepticism, to Berkeley's rejection of realism. In this paper, I consider how this move from dreams to idealism is supposed to work.

A Panchromatic View of Relativistic Jets in Narrow-Line Seyfert 1 Galaxies

open access: yesGalaxies, 2016
The discovery by the Large Area Telescope on board Fermi of variable γ-ray emission from radio-loud narrow-line Seyfert 1 (NLSy1) galaxies revealed the presence of a possible third class of Active Galactic Nuclei (AGN) with relativistic jets in addition ...

A Theory of Leadership Meta‐Talk and the Talking‐Doing Gap

open access: yesJournal of Management Studies, Volume 63, Issue 6, Page 2861-2893, September 2026.
Abstract We identify managers' meta‐level talk about the positive purpose, meaning, and significance of their actions as an overlooked type of leadership behaviour and call it leadership meta‐talk. We outline why leadership meta‐talk is not necessarily truthful or deceptive, but selective and loosely coupled with leadership practice.

Inverse Compton Emission and Cooling of Relativistic Particles Accelerated at Shear Boundary Layers in Relativistic Jets

open access: yesThe Astrophysical Journal
Both observational evidence and theoretical considerations from magnetohydrodynamic simulations of jets suggest that the relativistic jets of active galactic nuclei (AGN) are radially stratified, with a fast inner spine surrounded by a slower-moving ...

Spinning the Past Forward: Recording, Archiving, and (Re‐)listening to Siberian Phonograph Cylinders From the Jesup North Pacific Expedition

open access: yesMuseum Anthropology, Volume 49, Issue 2, Fall 2026.
ABSTRACT The article examines the history of phonographic recordings from the Jesup North Pacific Expedition (1897–1902), a venture that shaped the methods of Siberian and Arctic anthropology for decades. The authors—a historical anthropologist, a curator, and an Indigenous Sakha scholar—trace how audio recordings made during the expedition have moved ...

Jets from a stellar-mass black hole are as relativistic as those from supermassive black holes

open access: yesNature Communications
Relativistic jets from supermassive black holes in active galactic nuclei are amongst the most powerful phenomena in the universe. Similar jets from stellar-mass black holes offer a chance to study the phenomena on accessible observation time scales ...
