Astronomy in a Low-Carbon Future
Christopher D. Matzner, Nicolas B. Cowan, René Doyon +12
The global climate crisis poses new risks to humanity, and with them, new challenges to the practices of professional astronomy. Avoiding the more catastrophic consequences of glob…
The Fragmenting Superbubble Associated with the HII Region W4
Jennifer L. West, Jayanne English, Magdalen Normandeau +1
New observations at high latitudes above the HII region W4 show that the structure formerly identified as a chimney candidate, an opening to the Galactic halo, is instead a superbu…
An Unusual System of HI Filaments near WR 5 and HD 17603
Lewis B. G. Knee, Bradley J. Wallace, Magdalen Normandeau
We report the discovery of a system of unusual HI filaments which appear to be associated with molecular clouds in the Perseus spiral arm of our Galaxy. We investigate the hypothes…
The W4 chimney/superbubble
Magdalen Normandeau
A conical void in the Galactic HI within the Perseus arm has been proposed to be a chimney. However, Halpha data suggest that the structure may be closed at higher latitudes and th…
The HI shell G132.6-0.7-25.3: A Supernova Remnant or an Old Wind-Blown Bubble?
Magdalen Normandeau, A. R. Taylor, P. E. Dewdney +1
Data from the Canadian Galactic Plane Survey reveal an abundance of HI shells and arcs in the disk of our galaxy. While their shape is suggestive of stellar winds or supernovae inf…
Probing the Interstellar Medium using HI absorption and emission towards the W3 HII region
Magdalen Normandeau
HI spectra towards the W3 HII complex are presented and used to probe the Galactic structure and interstellar medium conditions between us and this region. The overall shape of the…
Radio polarimetric imaging of the interstellar medium: magnetic field and diffuse ionized gas structure near the W3/W4/W5/HB3 complex
A. D. Gray, T. L. Landecker, P. E. Dewdney +3
We have used polarimetric imaging to study the magneto-ionic medium of the Galaxy, obtaining 1420 MHz images with an angular resolution of 1' over more than 40 square-degrees of sk…
Observations and Modeling of the Disk-Halo Interaction in our Galaxy
Magdalen Normandeau, Shantanu Basu
Galaxies are surrounded by large halos of hot gas which must be replenished as the gas cools. This led Norman & Ikeuchi (1989) to propose the chimney model of the interstellar medi…
