SiO Emission from the Orion Nebula [PDF]
Symposium - International Astronomical Union, 1980 SiO emission in both a strong maser transition in the first excited vibrational state and in a weaker transition in the ground vibrational state both arise from the same small region in the Kleinmann-Low Nebula in Orion. Within the errors, the source position coincides with that of the infrared source IRc2.

Rings and Jets around PSR J2021+3651: the `Dragonfly Nebula'
, 2008 We describe recent Chandra ACIS observations of the Vela-like pulsar PSR J2021+3651 and its pulsar wind nebula (PWN). This `Dragonfly Nebula' displays an axisymmetric morphology, with bright inner jets, a double-ridged inner nebula, and a ~30" polar jet.

Epileptic Disorders, EarlyView.Abstract The ILAE Neuroimaging Task Force aims to publish educational case reports that highlight basic aspects of neuroimaging in epilepsy consistent with the ILAE's educational mission. Here, we describe a case series of three neonates with focal cortical dysplasia (FCD)‐related drug‐resistant epilepsy who underwent surgical intervention. The purpose

LMC X-1: A New Spectral Analysis of the O-star in the binary and surrounding nebula [PDF]
, 2017 We provide new observations of the LMC X-1 O star and its extended nebula structure using spectroscopic data from VLT/UVES as well as H$\alpha$ imaging from the Wide Field Imager on the Max Planck Gesellschaft / European Southern Observatory 2.2m ...

Nebulae (emission / absorption)
Culture and Cosmos, 2012 My presentation consists of a collage on panel. Using colour laser copies of nebulae, the dual composition recombines torn pieces of several nebular images. Optically entangled from light colour patterns, the focus of each nebula resembles the opposing behaviour of absorption and emission nebula. The collages include false colour composite astronomical

The morphology of dust emission in Planetary Nebulae and proto-Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1997 This review covers recent results from ground based mid-infrared (mid–IR; 8–25μm) imaging of thermal dust emission. The mid–IR images of proto–PNe show evidence for axially symmetric superwinds. In young PNe, the dust appears to be well mixed with the gas in the ionized gas regions.

Emission-Line Fluxes of Northern Planetary Nebulae [PDF]
Publications of the Astronomical Society of Australia, 2015 AbstractWe present long slit spectrophotometric emission line fluxes of bright and extended (< 5 arcsec in diameter) planetary nebulae (PNe), selected from a catalogue with suitable equatorial coordinates for northern hemisphere. In total, 17 planetary nebulae have been chosen and observed in 2008–2010.

Bulbs and Biopower: Managing Produce and Price in the Age of Agri‐Logistics
Antipode, EarlyView.Abstract This paper deploys the material and discursive politics of storage as a lens into agrarian change in rural India. Focusing on onions (Allium cepa), a price volatile crop and a kitchen staple, it maps out the contested meanings of and motivations for storage among growers, governments, and agri‐logistics companies. Specifically, this paper asks
