Playing with the autoethnographical: Performing and re-presenting the fan's voice

© 2014 SAGE Publications. My article plays with notions of performativity and representation to repudiate assumptions of one-dimensional fandom. In particular, due to its self-reflexive writing style, I argue that autoethnography can articulate and show the subject-fan voice through evocations of first-person, insider experiences. Therefore, staged vignettes are deployed to represent the fan as an assemblage of investments, intensities, and energies that anchor within but fluidly move through broader socio-cultural realities. Illuminating the materialization and salience of affect, these stagings intentionally convey varying levels of invigoration to refute common misperceptions of fandom as singular in its focus, experience, or intensity. Moreover, underpinning these renditions is a degree of playfulness, crafting autoethnography to explore both the subject and fandom as an enacted series of performances. Ultimately, as a performative writing and representational strategy, the vignettes aim to blend, blur, and elicit traces of a culturally bound and multifaceted first-person fandom

XMM-Newton observations of SNR 1987A. II. The still increasing X-ray light curve and the properties of Fe K lines

Aims. We report on the recent observations of the supernova remnant SNR 1987A in the Large Magellanic Cloud with XMM-Newton. Carefully monitoring the evolution of the X-ray light curve allows to probe the complex circumstellar medium structure observed around the supernova progenitor star. Methods. We analyse all XMM-Newton observations of SNR 1987A from January 2007 to December 2011, using data from the EPIC-pn camera. Spectra from all epochs are extracted and analysed in a homogeneous way. Using a multi-shock model to fit the spectra across the 0.2-10 keV band we measure soft and hard X-ray fluxes with high accuracy. In the hard X-ray band we examine the presence and properties of Fe K ines. Our findings are interpreted in the framework of a hydrodynamics-based model. Results. The soft X-ray flux of SNR 1987A continuously increased in the recent years. Although the light curve shows a mild flattening, there is no sudden break as reported in an earlier work, a picture echoed by a revision of the Chandra light curve. We therefore conclude that material in the equatorial ring and out-of-plane HII regions are still being swept-up. We estimate the thickness of the equatorial ring to be at least 4.5x10^16 cm (0.0146 pc). This lower limit will increase as long as the soft X-ray flux has not reached a turn-over. We detect a broad Fe K line in all spectra from 2007 to 2011. The widths and centroid energies of the lines indicate the presence of a collection of iron ionisation stages. Thermal emission from the hydrodynamic model does not reproduce the low-energy part of the line (6.4-6.5 keV), suggesting that fluorescence from neutral and/or low ionisation Fe might be present.Comment: 4 pages, 3 figures, 2 tables.
