Infrared Observations of the Helix Planetary Nebula [PDF]
We have mapped the Helix (NGC 7293) planetary nebula (PN) with the IRAC instrument on the Spitzer Space Telescope. The Helix is one of the closest bright PNs and therefore provides an opportunity to resolve the small-scale structure in the nebula.

Discovery of an OVI Emitting Nebula around the Hot White Dwarf KPD 0005+5106
A survey of diffuse interstellar sight lines observed with the Far Ultraviolet Spectroscopic Explorer has led to the serendipitous discovery of a high-ionization nebula around the hot white dwarf KPD 0005+5106.

A spatially resolved plerionic X-ray nebula around PSR B0540-69 [PDF]
We present a high resolution Chandra X-ray observation of PSR B0540-69, the Crab-like 50 msec pulsar in the Large Magellanic Cloud. We use phase-resolved imaging to decompose the extended X-ray emission, as expected of a synchrotron nebula, from the ...

Abstract Fossil fuel workers are central protagonists in achieving a “just transition” to a greener and fairer economy. This article examines workforce attitudes towards transition, redundancy, and restructuring following Petroineos’ announcement that the Grangemouth oil refinery in Scotland would close by 2025.

Housing Crisis or Immiseration? Revisiting the Housing Question under Urban Capitalism
Abstract The phrase “housing crisis” proliferates in media, politics, and scholarship, and has become the go‐to compound noun for depicting the urgency of the manifold social ills associated with widespread, deteriorating housing affordability. Instead of referring to a temporally and spatially bound event, however, the phrase now has become a ...

Inductive spikes in the Crab Nebula - a theory of gamma-ray flares
We show that the mysterious, rapidly variable emission at ~400 MeV observed from the Crab Nebula by the AGILE and Fermi experiments could be the result of a sudden drop in the mass-loading of the pulsar wind.

Business ethics, law and zemiology: The criminology of social and environmental harm
Abstract This speculative paper introduces zemiology, an extension of radical criminology which explores why many ‘crimes’ are not ‘illegal’ by focussing on the problem of ‘social harm’. Zemiology insists that we should begin with social or environmental problems, and not allow their foreclosure by the distraction of whether a particular practice is ...

Detection of Pre-Shock Dense Circumstellar Material of SN 1978K [PDF]
The supernova SN 1978K has been noted for its lack of emission lines broader than a few thousand km/s since its discovery in 1990. Modeling of the radio spectrum of the peculiar SN 1978K indicates the existence of HII absorption along the line of sight ...
