Who am I?
I did my masters and PhD at Leiden Observatory in the
Netherlands. On October 1 1999, I started as a postdoc at
Queen's University, working with
Dr. J. Irwin on the
connection between the disk and halo of galaxies. As of October 1 2001
I am a postdoc in the radio astronomy group working with
Dr. Russ Taylor in the IGPS consortium

A Majestic Gas Shell Revealed by the VLA

(U. Calgary)
This image from the VLA Galactic Plane Survey Stil et
al. (2006) AJ 132, 1158 won the 2006 NRAO/AUI image contest for the
best radio astronomy image.
The location
of the shell in our Galaxy with respect to the Sun (circle with dot in
the panel on the right). The location of the shell is marked by the
blue diamond. We believe the shell is located in the Perseus spiral
arm as shown in this image. The topmost panel shows a wide panorama
of radio emission from hot gas in the Galactic plane, while the shell
itself is made up of much cooler gas. The blue rectangle
indicates the field of view centered on the shell (lower left).
