Blue straggler formation at core collapse

open access: yes, 2016
Among the most striking feature of blue straggler stars (BSS) is the presence of multiple sequences of BSSs in the colour-magnitude diagrams (CMDs) of several globular clusters. It is often envisaged that such a multiple BSS sequence would arise due a recent core collapse of the host cluster, triggering a number of stellar collisions and binary mass ...

The perplexity of Christmas trees: ageing, errantry, and intersectional time La perplexité des arbres de Noël : vieillissement, errance et temps intersectionnel

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
What is offered by considering ageing, ethics, and intersectionality from a critical phenomenological perspective that draws upon critical race theory? Based upon an extended ethnography of African Americans raising children with illnesses and disabilities, I consider the Christmas trees that a grandmother lovingly decorated each year.

Bulbs and Biopower: Managing Produce and Price in the Age of Agri‐Logistics

open access: yesAntipode, EarlyView.
Abstract This paper deploys the material and discursive politics of storage as a lens into agrarian change in rural India. Focusing on onions (Allium cepa), a price volatile crop and a kitchen staple, it maps out the contested meanings of and motivations for storage among growers, governments, and agri‐logistics companies. Specifically, this paper asks

A unified multi‐scale method for simulating immersed bubbles

open access: yesComputer Graphics Forum, EarlyView.
Abstract We introduce a novel unified mixture‐based method for simulating underwater bubbles across a range of bubble scales. Our approach represents bubbles as a set of Lagrangian particles that are coupled with the surrounding Eulerian water volume. When bubble particles are sparsely distributed, each particle, typically smaller than the liquid grid ...
