A future for Hashima: pornography, representation and time

This article sets out to investigate the relationship between ruins, futurity, and ‘ruin porn’ - a visual mode of representation that all too often seeks to fix post-industrial ruins as mere aesthetic objects, devoid of history and/or temporality. It does so by focusing on performance, which, in this context, is understood as a processual mode of art-making that provides spectators with an experience of time. In this expanded definition of performance, as one may perhaps expect, the performativity of the object is not limited to the theatrical event alone; rather, it now inheres in sometimes uncanny durational aspects of both still and moving images. The essay proceeds in three stages. Part one provides a historical and theoretical overview of the type of performance inherent in ‘ruin porn’; part two critiques two images from Yves Marchand's and Romain Meffre's Gunkanjima (2013), a photo album that attempted to document the ruins of Hashima, an island situated 15 kilometres from Nagasaki City in the East China Sea; and part three investigates the very different aesthetic at work in Lee Hassall's film Return to Battleship Island (2013) which was made in response to AHRC- funded project, ‘The Future of Ruins: Reclaiming Abandonment and Toxicity on Hashima Island’ (2013). In this reading of Return to Battleship Island , the onus is on showing how Hassall's film, in its representation of Hashima's crumbling apartment blocks and industrial buildings, intentionally sought to contest the atemporal logic of ‘ruin porn’ by attempting to endow the viewing experience with a sense of futurity. Crucially, this does not mean that film represented the future as an object, but, on the contrary, tried to make it palpable, as something one undergoes physically in the very act of reception

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
