- We give an overview and describe the rationale, methods, and first results from NIRCam images of the JWST “Prime Extragalactic Areas for Reionization and Lensing Science” (PEARLS) project. PEARLS uses up to eight NIRCam filters to survey several prime extragalactic survey areas: two fields at the North Ecliptic Pole (NEP); seven gravitationally lensing clusters; two high redshift protoclusters; and the iconic backlit VV 191 galaxy system to map its dust attenuation. PEARLS also includes NIRISS spectra for one of the NEP fields and NIRSpec spectra of two high-redshift quasars. The main goal of PEARLS is to study the epoch of galaxy assembly, active galactic nucleus (AGN) growth, and First Light. Five fields—the JWST NEP Time-Domain Field (TDF), IRAC Dark Field, and three lensing clusters—will be observed in up to four epochs over a year. The cadence and sensitivity of the imaging data are ideally suited to find faint variable objects such as weak AGN, high-redshift supernovae, and cluster caustic transits. Both NEP fields have sightlines through our Galaxy, providing significant numbers of very faint brown dwarfs whose proper motions can be studied. Observations from the first spoke in the NEP TDF are public. This paper presents our first PEARLS observations, their NIRCam data reduction and analysis, our first object catalogs, the 0.9–4.5 μm galaxy counts and Integrated Galaxy Light. We assess the JWST sky brightness in 13 NIRCam filters, yielding our first constraints to diffuse light at 0.9–4.5 μm. PEARLS is designed to be of lasting benefit to the community.

Decolonial Gothic : Beyond the Postcolonial in Gothic Studies
- 2022

- This article theorises decolonial Gothic as a novel approach to Gothic fiction from formerly colonised regions and communities. It responds to an emerging body of Gothic production, which situates itself in a world shaped by persistently racialised distributions of social and environmental precarity, and where colonial power is thus an enduring material reality. To address such fiction, the article proposes, requires a reassessment of the hauntological frameworks through which Gothic and the (post)colonial have hitherto been brought into contact. Forged in the cultural climate of late-twentieth-century postmodernity, these hinge on the assumption of an epochal break, which renders colonial history a thing of the past; thus, they fall short of narratives that engage with active formations of colonial power. Accordingly, the article outlines an alternative approach, positioning Gothic fiction in the context of the capitalist world-system, which – into the present – is structured by colonial categories of race, heteropatriarchal categories of gender, and instrumentalising discourses of nature as plunderable resource.

Decolonising the COVID-19 pandemic : On Being in this Together

Tidskriftsartikel (refereegranskat)abstract
- At its inception, the COVID-19 pandemic was described as something inherently new, capable of crossing and erasing the economic, racial, gendered, and religious divides that stratify societies around the world. However, the ongoing pandemic is not new or egalitarian, but fuelled by, and fuelling, crises already under way on a global scale. In this article we examine on the one hand the relationship between the pandemic and still-active formations of racialised and gendered power, and on the other the pandemic's inextricability from a dispersed and uneven planetary emergency. As the environmental historian Jason W. Moore notes, this emergency disproportionately affects ‘women, people of colour and (neo)colonial populations’ (2019: 54), and the effects of COVID-19 are similarly unevenly allocated.

Haunted Technonature : Anthropocene Coloniality in Ng Yi-Sheng’s Lion City
- 2021
-
Ingår i: Haunted Nature. - Cham : Palgrave Macmillan. - 9783030818685 - 9783030818692 - 9783030818715 ; , s. 135-158
-
Bokkapitel (refereegranskat)abstract
- This chapter moves away from the established strand of literary ecocriticism in which haunted nature is situated in the Anthropocene and instead examines how Anthropocene thinking itself becomes subject to haunting in speculative fiction. To make this argument, it focuses on Ng Yi-Sheng’s collection Lion City (2018): a text that maps connections between Singapore’s colonial history and the nation’s contemporary status as a model for climate survival through geoengineering and “technonature.” This analysis proposes that rather than mobilizing the speculative to describe human effects on the biosphere (as much criticism suggests), Ng’s tales excavate legacies of environmental injustice repressed by the paradigm of anthropogenesis. In doing so, the narrative critiques Anthropocene accounts of emergency and highlights the necessity of decolonizing the narrative of crisis itself.

Introduction : The Body in Postcolonial Fiction after the Millennium

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Since the turn of the millennium, debates in postcolonial studies and world literature have repeatedly shown the realities of empire to be continuing, immediate and visceral. What has been overlooked thus far are the ways in which the bodily has re-emerged in postcolonial cultural production as a receptor to, and vocabulary for, these immanent violences. Fictions from across the global south are drawing with apparently increasing frequency on corporeal lexica in their imaginings of on-going imperial circumstances. At the same time, the new millennium has witnessed the rise, in multiple postcolonial contexts, of speculative genres - science fiction and horror pre-eminent among them - to which the body is central. Together, all of this suggests the need for renewed reflection on the poetics and functions of the bodily in contemporary fictional engagements with empire. This special issue takes up this imperative. Our interest lies with the grammars and technologies offered by the corporeal in postcolonial cultural production since the millennium, and in the possibilities and limitations of these bodily registers. Over the course of this introduction, we outline the material, narrative and theoretical contexts within which we see the body re-emerging as a site of renewed critical and literary or cinematic potential. We return to established analytical categories for the corporeal in postcolonial literary studies, and show that current fictional handlings of the body and embodiment appear resistant to interpretation via these rubrics. Taking our cue both from a materialist theoretical (re)turn that corresponds to the turn of the millennium and from aesthetic developments in literature and film of the same period, we go on to lay the groundwork for an approach to the body as this is currently emerging in contemporary postcolonial and peripheral imaginaries.
