Reading the postcolonial island in Amitav Ghosh's The Hungry Tide.

This paper argues that literature has much to contribute to the theoretical work of island studies, and not just because literary texts provide evidence of the ways islands are conceptualized in different historical and cultural contexts. To this end, it discusses Amitav Ghosh’s The Hungry Tide (2004), a novel which actively theorizes key concepts in island studies. The Hungry Tide is set in the Sundarbans, an “immense archipelago” in the Ganges delta, and tells the largely forgotten history of the forced evacuation of refugees from the island of Morichjhãpi in 1979. The liminal space of the Sundarbans, the “tide country”, is an extraordinary setting for a literary exploration of the relationship between postcolonial island geographies and identities. Ghosh’s depiction of the “watery labyrinth” (Ghosh, 2004: 72) and “storm-tossed islands” (Ghosh, 2004: 164) of the Sundarbans raises and addresses questions, which should be at the heart of the critical meta-discourse of island studies

Historical Romance, Gender and Heterosexuality: John Fowles's The French Lieutenant's Woman and A.S. Byatt's Possession

This essay is a comparative analysis of two historical romance novels: John Fowles’s The French Lieutenant’s Woman and A.S. Byatt’s Possession. While I acknowledge that some of the key storytelling priorities in Possession oppose those of The French Lieutenant’s Woman, I emphasise structural similarities in the treatments of the heroines in these two novels. My analysis of the characterisation and narrative function of Sarah Woodruff and Christabel LaMotte illustrates the novels’ common paradigmatic structure and reveals a deeper shared allegiance to heterosexual hegemony. I argue that these characters are crucial to the complex negotiation of the past which both novels offer. They enable, in Diane Elam’s words, “a re– engendering of the historical past as romance.” Sarah and Christabel’s representation as both historical and outside of history provides the conduit for the elaborate to–ing and fro–ing between the Victorian age and the late twentieth century which is central to both novels. The double aspect of these characters depends on allegorical stereotyping of women as “mystery” and “truth.

Intermediate behavior of Kerr tails

The numerical investigation of wave propagation in the asymptotic domain of Kerr spacetime has only recently been possible thanks to the construction of suitable hyperboloidal coordinates. The asymptotics revealed an apparent puzzle in the decay rates of scalar fields: the late-time rates seemed to depend on whether finite distance observers are in the strong field domain or far away from the rotating black hole, an apparent phenomenon dubbed "splitting". We discuss far-field "splitting" in the full field and near-horizon "splitting" in certain projected modes using horizon-penetrating, hyperboloidal coordinates. For either case we propose an explanation to the cause of the "splitting" behavior, and we determine uniquely decay rates that previous studies found to be ambiguous or immeasurable. The far-field "splitting" is explained by competition between projected modes. The near-horizon "splitting" is due to excitation of lower multipole modes that back excite the multipole mode for which "splitting" is observed. In both cases "splitting" is an intermediate effect, such that asymptotically in time strong field rates are valid at all finite distances. At any finite time, however, there are three domains with different decay rates whose boundaries move outwards during evolution. We then propose a formula for the decay rate of tails that takes into account the inter--mode excitation effect that we study.Comment: 16 page

The H₃⁺ ionosphere of Uranus: decades-long cooling and local-time morphology

The upper atmosphere of Uranus has been observed to be slowly cooling between 1993 and 2011. New analysis of near-infrared observations of emission from H₃⁺ obtained between 2012 and 2018 reveals that this cooling trend has continued, showing that the upper atmosphere has cooled for 27 years, longer than the length of a nominal season of 21 years. The new observations have offered greater spatial resolution and higher sensitivity than previous ones, enabling the characterization of the H₃⁺ intensity as a function of local time. These profiles peak between 13 and 15 h local time, later than models suggest. The NASA Infrared Telescope Facility iSHELL instrument also provides the detection of a bright H₃⁺ signal on 16 October 2016, rotating into view from the dawn sector. This feature is consistent with an auroral signal, but is the only of its kind present in this comprehensive dataset
